Your advice helped me to install the Math::GSL 0.22, but I found that in order to use the math functions that I need for Math::GSL 0.22, I have to use gsl v 1.13, which I haven't installed yet. I tried using cgywin to build the gsl v1.13 sourcecode, but it seems to have trouble with my gcc compiler.

The config.log file says the following:

 configure:3388: $? = 0

Any suggestions?

The current version is 1.14 - best to grab it.

With Cygwin, I think you'll need to use *their* gcc compiler, and then cross-compile for Windows (otherwise you'll end up with a gsl library that can be used only with Cygwin). I think the error you see is because you're using MinGW's gcc with Cygwin - the config.log would probably contain a diagnostic that pinpoints the specific problem.

I use the msys shell with MinGW, but if you want to build using Cygwin, try:

./configure --disable-static --enable-shared --host=i686-pc-mingw32 --build=i686-pc-cygwin CXX="g++ -mno-cygwin" CC="gcc -mno-cygwin" host_alias=i686-pc-mingw32 --prefix=/cygdrive/c/wherever && make && make install

and that should build it for native Win32.
Because it's a cross-compilation, I don't think there's any way of running 'make check'. Also, I think there might be some redundancy in the configure options I've provided - but that incantation has worked fine for me on the occasions that I've tried it. (Haven't tried it with gsl, but.)
See how that goes. (/msg me when you reply, otherwise I might miss it.)

Btw, I have now built Math::GSL-0.22 ppm packages - which you can install with:

(Update: The following command has been corrected ... was originally incorrect.)
ppm install http://www.sisyphusion.tk/ppm/Math-GSL.ppd

That should also install the gsl dll that's needed (via a post-install script that should launch automatically as part of the 'ppm install' process).

Cheers,
Rob

Update: I'm a bit out of date with Cygwin. On my Cygwin-1.7.7, I need to install gcc-3.4.4 (via Cygwin's setup.exe) and run:

./configure --disable-static --enable-shared --host=i686-pc-mingw32 --build=i686-pc-cygwin CXX="g++-3 -mno-cygwin" CC="gcc-3 -mno-cygwin" host_alias=i686-pc-mingw32 --prefix=/cygdrive/c/wherever && make && make install

This is actually being run as I write ... (update: and ran fine).
My Cygwin-1.7.7 uses gcc-4.3.4 by default, which doesn't accommodate cross-compilation.

With Cygwin-1.5.x (which already uses gcc-3.x.x), the original incantation should work fine.

I checked for your ppm package, but the link is down on your website. Could you put it back up?

Thanks, Jeff
