Lawrence RE: lapack.so: no such file [ reply ]   2008-09-06 21:40 This is fixed in the 1.0.0 release, where I now check DLEXT in rbconfig. I have included a Mac binary of Linalg as well, using g77 from http://hpc.sourceforge.net/ By: Parker Morse RE: lapack.so: no such file [ reply ]   2008-03-26 19:32 The problem is that the install.rb file builds lapack.bundle and linalg.bundle rather than lapack.so and linalg.so on the Mac. I suspect this is due to a change in mkmf since this file was created, but I'm not sure. I was able to force an install by issuing `ruby install.rb make`, renaming the .bundle files to .so files (in ext/lapack and ext/linalg) and then running `sudo ruby install.rb install`.

I recently needed to install linalg after downloading the scripts on the following site: http://www.igvita.com/blog/2007/01/15/svd-recommendation-system-in-ruby/ When I tried to run the file, which required 'linalg' I get the following error: /usr/local/lib/ruby/site_ruby/1.8/lapack.rb:7:in `require': no such file to load -- lapack.so (LoadError) from /usr/local/lib/ruby/site_ruby/1.8/lapack.rb:7 from /usr/local/lib/ruby/site_ruby/1.8/linalg.rb:7:in `require' from /usr/local/lib/ruby/site_ruby/1.8/linalg.rb:7 from svd-recommender.rb:1:in `require' from svd-recommender.rb:1 I thought that I needed to install the stand-alone version of LAPACK in order to fix this. So I followed instructions on: http://www1.gly.bris.ac.uk/~wookey/MEFTLG/g77.htm I successfully installed the g77 compiler, needed to compile LAPACK 3.1.1. After successfully installing and testing LAPACK, I tried running the script and again, I get the same error. I have checked my paths and all are correct. I looked in the install logs of linalg and verified that lapack.so was in the correct directory and had the correct permissions. I am running Intel OSX 10.4.10 with ruby 1.8.5 (2006-08-25) [i686-darwin8.9.1] Any help or comments would be greatly appreciated. I'll report back to this thread if I find anything.
