Dear Pierre, I confused names - the guide was not written by Brad Chapan, but by Brian Gladman, and it is available over here:
http://gladman.plushost.co.uk/oldsite/computing/gnu_scientific_library.php however, I realized that trying to use libraries compiled with Visual Studio 2010 against minGW might not work as well as I'd like, so I just downloaded msys for minGW, and compiled the GSL with minGW using msys, and that went smoothly. After doing that, I obtained a 'normal' directory structure, and I was able to build pyGSL fine, so the installation went well. After the installation, I tried following the readme file directions and changed to the /tests directory, and ran: python run_test.py - and got the following message: C:\TEMP\pygsl-0.9.5\tests>python run_test.py Did you try to import pygsl in the build directory? Well, that does not work out of the box. If you want to do that, please use python setup.py build_ext -i to add the necessary extension module in the local pygsl/ directory! Please read the README first! Any further questions or missing information please post to [email protected]! Traceback (most recent call last): File "run_test.py", line 69, in <module> run() File "run_test.py", line 47, in run import pygsl File "C:\Python27\lib\site-packages\pygsl\__init__.py", line 57, in <module> import pygsl.init ImportError: DLL load failed: The specified module could not be found. C:\TEMP\pygsl-0.9.5\tests> I wasn't in the directory, but I tried to fix it by doing: python setup.py build_ext -i as reccomanded, then repeating the command. This runs fine with no errors/bugs, but doesn't fix the problem, I get the same error about missing DLL. Is there a PATH file that is not set or what exactly is the DLL that the program is failing to run?
