[pygsl-discuss] GSL-compilation solution (thanks for the help)

[federico v. <vag...@gm...>]

After extensive help from Pierre and Sebastian, I managed to finally import
the pyGSL in Windows.

Since I had extensive help for doing so, I'll try to post a semi-detailed
walk through in case it can be helpful for other people.

1 - Download the GSL from the GNU website.

2 - Download minGW with msys - this is important, without it, you'll have to
edit the make files.

3 - Compile the GSL with msys.  By default, msys will put all the library
files in subdirectories there - these will be c:/minGW/msys/1.0/ - I copied
the compiled files and placed them in a C:/GSL/

4 - At this point, I was able to compile pyGSL and build it, but I still
wasn't able to import it - I was getting warnings about pyGSL being unable
to find the required DLL files.

5 - To import the GSL, I followed the steps suggested by Sebastian, and
copied a few extra .DLL files that were NOT placed with the other files in
the subdirectory described in 3.

The real names of the dynamic libraries to copy in the python/pygsl
directory (after install it)  is libgsl-0.dll,  libgslcblas-0.
dll and libgcc_s_dw2-1.dll.

libgsl-0.dll and  libgslcblas-0.dll are build with MinGw, they are located
in the bin/ directory. If you juste type ./configure , make and make
installl, they are here: "C:\"MinGW\msys\1.0\local\bin
The last dll :  libgcc_s_dw2-1.dll is in the directory : "C:\"MinGW\bin

6 - After copying those files, I was able to import and run the tests in the
tests subdirectory.  A small note, a few of the tests fail, in particular:

histogram_test
linalg_test
permutation_test

I can dig deeper into those if that's helpful.  The shell didn't leave any
useful messages unfortunately.

Thanks everyone for all the help,

Federico
