 RE: Unable to install on cygwin [ reply ]

I am getting the below error -
/usr/lib/ruby/gems/1.8/gems/gsl-1.12.109/lib/rb_gsl.so: /usr/lib/ruby/gems/1.8/gems/gsl-1.12.109/lib/rb_gsl.so: undefined symbol: gsl_multimin_fminimizer_nmsimplex2rand - /usr/lib/ruby/gems/1.8/gems/gsl-1.12.109/lib/rb_gsl.so (LoadError)
Any clue what this is related to?
I had compiled from the source once, but then removed the files in site_ruby folder and installed v1.12 as a gem.
I am working on Ubuntu 9.10..

# I am not the maintainer of any pre-compiled rb-gsl packages for Linux distributions or cygwin.
It seems that the rb-gsl package you installed had been compiled with NArray extension support (NArray is a ruby extension library for N-dimension array manipulations). So check it before the rb-gsl installation, and try again.
If you compile rb-gsl by yourself from a source tree, the configuration script (setup.rb) searches NArray and sets an appropriate flag to build rb-gsl.

Hi all,
I am trying to install on ubunty-hardy, x86-64, but seem to get this error when I try to run a simple test.
/usr/lib/ruby/1.8/x86_64-linux/rb_gsl.so: /usr/lib/ruby/1.8/x86_64-linux/rb_gsl.so: undefined symbol: cNArray - /usr/lib/ruby/1.8/x86_64-linux/rb_gsl.so (LoadError)
from /usr/local/lib/site_ruby/1.8/rbgsl.rb:1
from ./rbtest.rb:2:in `require'
from ./rbtest.rb:2
I have 1) used apt-get to install Ruby/GSL 2) downloaded prebuilt ubuntu binary 3) tried to build from source 4) uninstalled everything, rebuilt from source/apt-getted GSL itself and repeated steps 1-3, but its all the same. I have also tried the "-I" option to specify location of
rb_gsl.so!
I must be doing something stupid, but any ideas would be helpful!
Thanks

Yoshiki,
I installed plotutils, but am still unable to use the graph feature:
for example the min.rb program produces the following:
finchc@C73XH1J ~/rubystuff/rb-gsl-1.9.0/samples
$ ruby min.rb
Using brent method
iter [ lower, upper] min err err(est)

Can you help with this problem?

Chris,
You can find some scripts for physical/astrophysical calculations in the samples/ directory. Some researchers extensively use Ruby/GSL in their studies, but I don't know any user groups or communities for Ruby/GSL. I believe Ruby/GSL is quite good choice for scientific computing with Ruby, enjoy easy scripting!

Yoshiki,
I changed the make utility from the MinGW version to the GNU version and it now works - great! I'm looking forward to using rb/GSL. Do you know of any science ruby groups I could contact about rb/GSL?
Regards,
Chris

Hi guys after doing ruby setup.rb config, I do ruby setup.rb setup and get the following error - I would be very grateful for your help.

I have found the answer.
The LoadError for rb_gsl.so is caused by pre-compiled gsl libraries that user installs using cygwin's setup.exe
I have removed cygwin binaries, downloaded latest gsl source (gsl-1.8) and compiled it myself under cygwin. After that, followed standard rb-gsl installation for rb-gsl-1.8.3.
Now 'require "gsl"' works under cygwin same as you would expect it under *nix. Plotutils bindings also work under cygwin X server.
Another detail: I have compiled my own ruby-1.8.4. For every library that has been compiled, the option --prefix=/usr has been used.

I did a clean install of everything once more (Infact, I reinstalled ruby, just to be sure). ruby setup.rb install does not give me any errors. All files are copied correctly,
[/usr/lib/ruby/site_ruby/1.8/i386-cygwin]$ ls -l
total 1401
-rw-r--r-- 1 Aditya Mahajan None 89060 Mar 12 14:28 libnarray.a
-rw-r--r-- 1 Aditya Mahajan None 4888 Mar 12 14:28 narray.h
-rwxr-xr-x 1 Aditya Mahajan None 122880 Mar 12 14:36 narray.so
-rw-r--r-- 1 Aditya Mahajan None 122 Mar 12 14:36 narray_config.h
-r-xr-xr-x 1 Aditya Mahajan None 1211904 Mar 12 14:40 rb_gsl.so
However, when I do require require "gsl" I still get the error
[/f/tmp/rb-gsl-1.7.0/tests]$ ruby cdf.rb
/usr/lib/ruby/site_ruby/1.8/i386-cygwin/rb_gsl.so: No such file or directory - /
usr/lib/ruby/site_ruby/1.8/i386-cygwin/rb_gsl.so (LoadError)
from /usr/lib/ruby/site_ruby/1.8/gsl.rb:2
from cdf.rb:2
The error message looks very strange to me and I do not understand it.

Unfortunately, I have no Windows box now, sorry.
But I just remembered my friend said: in Cygwin environment,
sometimes ruby setup.rb install fails and
an extension *.so does not copied correctly.
Please copy rb_gsl.so by-hand into some lib
directory, and try again. How about it?

Thanks for the pointer. I copied libnarray.a to /usr/lib/ and was able to install gsl. However, I am still not able to use it. When I do
require "gsl"
in a ruby program, I get the error
/usr/lib/ruby/site_ruby/1.8/i386-cygwin/rb_gsl.so: No such file or directory - /
usr/lib/ruby/site_ruby/1.8/i386-cygwin/rb_gsl.so (LoadError)
from /usr/lib/ruby/site_ruby/1.8/gsl.rb:2
I do not understand this error message. rb_gsl.so in present in the above path, I do not know why it can not be loaded. Any hints?

Hi,
When I try to install on cygwin, I get the following error message. As I understand, the linker can not link to narray, even though narray.h is present. How do I correct this?
Thanks
Aditya
