Subject: [fxruby-users] [ANN] FXRuby 1.4.3 Now Available
Message-ID: <33a09cd74ae3138f53b250d40ddb58a5@knology.net>

All,

FXRuby version 1.4.3 is now available for download from this page:

	http://rubyforge.org/frs/?group_id=300&release_id=3402

For a summary of the changes in this release, please see this page:

	http://www.fxruby.org/doc/changes.html

As usual, the code is provided as a Win32 installer or a binary Gem 
(both compatible with the latest One-Click Installer for Ruby 1.8.2), 
as a source gem, and as a source tarball. For instructions on compiling 
FXRuby from source, please see:

	http://www.fxruby.org/doc/build.html

And as always, the FXRuby home page is here:

	http://www.fxruby.org

Enjoy,

Lyle

When you build FXRuby, as a last step it links against some FOX library. The
fact that you're seeing the rectangle with "PNG" indicates that FXRuby is
linked against a FOX library that was built *without* PNG support.

If the imageviewer example (for regular FOX) is working, that may indicate
that you have multiple versions of FOX installed and that FXRuby is linked
against some build that didn't have PNG support enabled.

Hello,
I am a Gentoo user.
I emerged Fox 1.4.11 with all features turned on recently.
Since FXRuby 1.4.x is not on Portage, I tried to install 1.4.2 manually.

install.rb config works with no problems at all.

install.rb setup aborts with the following output:

Diego,

The compilation problem you're seeing is due to an error that was 
present in the FOX header files for FOX versions 1.4.11 and earlier. 
This bug was fixed in FOX version 1.4.12; see:

	http://www.fox-toolkit.com/news3.html

and the release information for FOX 1.4.12 appears about halfway down 
the page. I recommend that you download and install the latest version 
of FOX 1.4 (which is now up to 1.4.24 I believe) and try again.

Hope this helps,

Lyle

Hi All:

  I've got an fxruby app that creates large dialog
forms -- mostly combinations of FXLabel, and
FXTextField.  It seems that after I've displayed some
finite number of them, it crashes the app.  I've
duplicated this with a simple app that you press a
button to display a new dialog.   The demo app doesn't
have the scrolling I've added to be able to see all
the entries, but seems to demonstrate the same thing
happening -- i.e. creating a certain number causes the
app to crash (4 for my laptop (windows XP), 6 on
citrix session (windows 2000).  I'm running from the
latest one click installer for windows.

  Any clues on either what I'm doing wrong or a
workaround?  Code follows.  Thanks in advance

No crash with fox14 (that's on linux though, so there may be other
variables).

Seems to work fine for me.  I can get it to display the form in a 1024x800  
desktop with no problem.  I tested it under fox12 and fox14 on windows.   
Latest one-click installer (installed only last week).

What Lyle says is correct; I don't usually change header files after a 
stable release, but in this extreme case the header file itself was where
the bug was, so there really wasn't any choice.

FOX 1.4.24 is the latest version with all the bug fixes.

Did you try clicking the button repeatedly?  I've
tried on 2 different winxp and 1 windows 2K machine
and I crash eventually, some with more clicks and some
with less?

Hi,
	I'm an experienced programmer (mostly perl for the last 10 years) who 
is very new to Ruby. I have just installed Foxgui on my powerbook and am 
now attempting to install FXRuby.

The setup step results in some undefined symbols when building fox14.bundle.

output from the config step:

The link between the undefined symbols and the messages from the setup 
relating to png, jpg and tiff libraries has not escaped me however I do 
not know exactly what it means.

libtiff, libjpeg and libtpng are all installed in /sw/lib

I'm using the Apple XCode compiler and the X distribution that comes 
with Tiger.

Clearly I'm missing something.  Any help appreciated.

It sounds as though the FOX library (which you built earlier) was 
compiled without JPEG, GIF and PNG support.

Am I correct to assume that since you have libjpeg and friends 
installed in /sw/lib, that you're using Fink? If so, it should be that 
the include files for those libraries are present in /sw/include. Check 
to see if, for example, there's a /sw/include/jpeglib.h.

If those include files are there, it's probably just that you didn't 
configure the FOX built to look in the /sw/include directory for 
include files. If it doesn't know to look there, it's not going to find 
jpeglib.h (and friends) and so it's going to assume that you don't have 
those libraries installed. To configure FOX to look there (in addition 
to the directories that it searches by default), try:

	cd fox-1.4.x
	setenv CPPFLAGS -I/sw/include
	setenv LDFLAGS "-L/sw/lib -L/usr/X11R6/lib"
	./configure

Watch the messages generated by "configure" for stuff relating to GIF, 
PNG and JPEG, and make sure that it's finding those libraries. Then 
you'll type:

	make

to recompile FOX, this time with support for those libraries. You 
shouldn't need to re-compile FXRuby when it's done, just re-link it and 
it should be fine.

Hope this helps,

Lyle

Indeed, you are right.  The idea with stubbing out if no image support
is available is to allow programs to continue to compile [and function!].

I've looked things over and we have this problem in three different
places:- for JPEG, PNG and TIFF support.  The other image types are
OK as they are always compiled in [no external libraries are required].

I've fixed these and one other minor problem and dropped the fixed sources
at:

	ftp://fox-toolkit.org/pub/fox-1.4.25.tar.gz


Hopefully, that takes care of the problem!

Thanks to Lyle I now have everything compiling and installing without 
obvious errors.  For the archive (if there is one) the problem was that 
fink does not have dev versions (i.e. packages that includes the 
compiler header files) of the many of the libraries.  What I did in the 
end was to get the source of the packages from their respective homes 
and install them from scratch.

This should have fixed the problem but for reasons completely beyond me 
the new version of libjepg caused the build of some of the fox libraries 
to die with errors relating to the table of contents and suggestions 
that I should run ranlib on the library to rebuild the toc.  Running 
ranlib did not fix the problem (surprise ;).  So I then reinstalled 
libjpeg from fink over the version I build from source leaving the the 
headers files in place.

This allowed fox to build and install without obvious errors.  Now 
FXRuby setup died with an error saying it could not locate one 
libtiff.3.dymn (or something like that)  I looked at the files in 
/sw/lib and put a link in for this file pointing to the library which 
had the full version number in its name.

Now everything appears to load and install nicely.

However (you guessed it ;) when I try and run the examples I get:

rful011 at bluebottle FXRuby-1.4.3]$examples/browser.rb
/sw/lib/ruby/site_ruby/1.8/powerpc-darwin/fox14.bundle: [BUG] Bus Error
ruby 1.8.1 (2003-12-25) [powerpc-darwin]

Abort trap


Confession time:
I did not disable GL in building fox as per instructions (reasoning: the 
instruction appeared to be quite old -- I know tiger supports GL so I 
decided to suck and see).

I also came across stuff on the web suggesting that the apple supplied 
ruby was misconfigured and that one had to fiddle with  rbconfig.rb.  I 
have not done this (on the grounds that one should not fix things until 
you are sure they are broken ;)

So are the bus errors consistent with either of these potential issues 
or should I be looking elsewhere.

When I get his going I volunteer to update the instructions for building 
  stuff on a tiger using apples Xcode and fink.

Cheers, Russell

Very curious. I got all of the packages in question from fink and 
managed to get the needed header files. I am still running Mac OS 10.3 
(haven't upgraded to Tiger) and so I don't know if they've changed 
things for the newer fink distributions.

Yes, OpenGL should work fine. Where did you find a suggestion to build 
FOX without OpenGL support? We need to get that advice out of 
circulation.

Yes, I have also heard this about the Ruby included with Tiger. The 
patch that's out there fixing a problem related to building C 
extensions (like FXRuby) and so I imagine it's worth investigating 
that.

That would be great. I still haven't upgraded to Tiger and don't get a 
lot of feedback from Mac OS X users.

Here's my experience with Tiger (Mac OS X 10.4.3) on a couple of  
PowerBooks. My skill with C begins and ends with "./configure; make;  
sudo make install" so ....

Fox 1.4.x compiles as-is from source from the command line if you  
have the Apple developer tools installed. The example programs work  
as they should -- if you remember to start your X server first.

On OS X 10.4.2, FXRuby (source or gem) wouldn't compile for me  
without the fixrbconfig gem. I am not sure if this is still necessary  
with 10.4.3, but I suspect so.

With the "fix," FXRuby compiles, but any attempt to use it dies with:
Module() error
Symbol not found in flat namespace
__ZN2FX10fxcheckJPGERNS_8FXStreamE

The DarwinPorts FXRuby port _does_ work, but it's at version 1.2. I  
made my own local port, changed all the "1.2"'s to "1.4"'s, and that  
worked, too.

So, what's different in DarwinPorts? Obviously, the link error points  
toward a missing JPEG library, and the only dependencies listed in  
the Portfile are libtiff, libpng, libjpeg, and libX11 for Fox. And  
"otool -L libFOX-1.4.0.dylib" shows the images libs as the only  
difference between working builds.

Long story short, I copied my DarwinPorts versions of libtiff,  
libpng, libjpeg
into /usr/lib on another PowerBook that does not have DarwinPorts nor  
Fink; recompiled Fox and FXRuby from source; and it worked.

I would bet that if OS X users download and compile the "Image  
Formats" libs on the Fox Download page first, we would be able to  
compile and run FXRuby, but I haven't put that to the test.

Hope that helps,
Scott

Hi Scott,
	Thanks for describing your experience and apologies for taking so long
to get back to you.  This is a back burner project for me and now that
it's weekend I've got some time to have another go.

I too ran into the image lib problems and 'solved' them by installing
from source the libraries from source. I then ran into issues with
libjpeg refusing to load and ended up copying the version from Fink back
over the one I installed from source (after checking that they were
built from the same version).  I still don't know what was going on here.

I tried rebuilding the libjpeg with the version from the fox
distribution site but, so far as I can tell it was identical to the one
I installed.

I have a horrible feeling that something got left from one of my aborted
install attempts and is now poisoning everything I try.  My next
strategy will be to go through /usr/local/ and /sw and remove all files
created since I started play with fox and starting again from scratch.

I'm also going to uninstall the image libs from fink.

fingers firmly crossed:)

Russell

OK, I just got hello world up on the screen!  It only took about 20 hours :)

It turns out that the install is reasonably straight forward so long as
you don't first shoot yourself in both feet by having two Ruby installs
on your machine ;)

When I starter paying with ruby I had not realised that tiger installed
ruby and so I had installed it from fink and by the time I came to play
with FXRuby I had forgotten this.  Once I  used dselect to remove the
fink version of Ruby thing started working much better.  This also
explained why I was able to compile extensions without running the the
fix program.

There are still issues with the graphics libraries and these can be very
confusing and difficult to diagnose.  The problem being that fox and
builds quite happily without them but things come unstuck with FXRuby
because it assumes they are in the links are in fox.bundle so you either
get an error running install.rb setup or when you run any fxruby app
(depending on the exact circumstance).

It would be helpful if the fxruby config step could check for the
existence of the routines in foxlib and give plain English statement of
the problem.

One other complication is that not only do you need the libraries you
also need the include files to build foxlib properly.  Fink does not
have dev versions of any of the libraries (i.e. the fink packages do
*not* include the header files).  It is therefore best to install all
the image libraries from source.  There are convenient links to the
necessary tar balls on the fox download page -- I also installed zlib
and bz2.

The last piece of the puzzle is that (for reasons unknown and possibly
specific to my setup) the libjpeg.a file that I installed had something
screwed with its table of contents and I had to run ranlib to fix this.

So I ended up taking much longer than I should have to do what is really
 quite a straight forward job. One other thing that tripped me up was
that I ended up with some libraries installed in /usr/local and some in
/sw (why oh why does fink install stuff in /sw??  NO I really don't want
to know ;)  my powerbook is now covered in bloody footprints ;)  My
excuse is that this is the first time I have tried to install any
substantial software from source under Mac OS. Oh yes, I'm also getting
old and stupid :)

So how does one go about installing fox/fxruby on MacOS 10.4?

1/ Install Apple Xcode tools (if not already installed) and copy the
tarballs for fox and fxruby to somewhere convenient.

2/ You also need to download and run the fix script so that the Apple
supplied ruby can build extensions.

sudo gem install fixrbconfig
sudo fixrbconfig

3/ check the prerequisite libraries (png, tiff and jpeg) *and* include
files in both /usr/local and /sw  (libraries in lib/ and include in
include/  -- files in lib/ have lib prepended to the name e.g. libpng).

If any are missing then rebuild that package from source (links on the
the fox download page).  All packages install in /usr/local by default
so if you have installed the from fink but are missing the include files
the use dselect to uninstall them first.

I had to run ranlib on libjpeg.a:

sudo ranlib /usr/local/lib/libjpeg.a

now you should be able to install fox and fxruby following the usual
instructions.

The key to a successful install is to have the graphic libraries all
present and correct *before* you start installing fox.

Lyle:  Please feel free to use this material to update the fxruby
install web pages.

One last note:  When I did my final build of fox.bundle (which I did by
descending into ext/fox, removing fox.bundle and running make) I got a
whole bunch of duplicate symbol warning for various tiff routines which
ld found in both libtiff and libfox.  I'm not sure what that was about
but the fox.bundle that resulted seems to work just fine.

Cheers, Russell

Thanks for the detailed write-up. I think you are right that previous  
broken installs can "pollute" your current install, even when you  
have everything right.

HI All:

  I installed the 1.4.3 gem on windows XP, and I get a
crash after presenting it 6 times.  Any ideas here? 
I'm gonna have to start to look at porting the whole
app to another window toolkit real soon now,  since I
need to generate more than 5 large forms.

  THanks in advance.

  Forrest

I forget, did someone suggest GC.disable? Doing that before open the
forms would help diagnose the problem: if it doesn't crash any more,
there's probably a dangling pointer somewhere in fxruby. The
intermittent behavior of the problem does suggest a memory bug...

Hi Joel:

  I put in a GC.disable.  Now after 4 clicks, the
forms stop appearing.  No crash, just no forms. 
Before, I'd get 4 forms with 4 clicks, click 5 gave no
form, click 6 crashed it.  

  So it looks like some problem in fxruby

Forrest,

Sorry for the delay in responding to this. I have been traveling some
(especially last week) and haven't been able to get to a Windows box to take
a look. I can reproduce the problem after five or six displays of the
dialog. I have filed a bug report about this and will try to get it
corrected ASAP.

As a side note, what kind of application is this that is going to require
the user to fill in on the order of 1800 text fields in a dialog box? I am
concerned that even after I correct the bug that's causing it to crash, that
you're going to have a unusable application on your hands.

  It ultimately to populate parameters for a
substantial simulation model.  THere are various
"sites" which have subsystems that need modeling. 
Only one of these subsystems has the huge number of
parameters which produced this problem.  FOr the most
part, these parameters are already in place, and
they're just tweaking the values.  I have a copy
function that allows them to copy the sets across
sites.

What about using a FXTable? Not as pretty, but 1800 text fields ain't 
exactly pretty either...

  Hmm, I could consider this, what I basically do is
traverse these arbitrarily nested data structures and
map  it into titles, entries, and sub buttons to open
up sub structures all on the fly (the data structure
definititions are ever evolving).  That being said, I
don't off the bat have a good idea of how to map that
to a table instead of just opening frames, and
plopping entries into them, and have it look somewhat
reasonable.  I'm open to ideas though.

Subject: [fxruby-users] Can't add text to FXCanvas
Message-ID: <20051201035949.48354.qmail@web51609.mail.yahoo.com>

I have a ruby program that uses a FXCanvas, and I have attached a FXDCWindow 
to control it. It lets me draw lines, rectangles and ellipses, but not text. 
If I attempt to draw text, I get the following error

This application has requested the Runtime to terminate it in an
unusual way.
Please contact the application's support team for more information.
>Exit code: 3

I also get this error if I try to set the font of the FXCanvas or the 
FXDCWindow.

I have a short sample program that shows this problem. Thanks for any help.
