First I compile using
gcc –Wall –I/Users/roberto/Desktop/gsl_universal_1.14/include –L/Users/roberto/Desktop/gsl_universal_1.14/libs/ –c sample.c

then I link using
gcc sample.o gsl_universal_1.14/libs/gsl/libgsl.a –o sample

cheers,
roberto

#include
#include
int main (void)
{
double x = 5.0;
double y = gsl_sf_bessel_J0 (x);
printf ("J0(%g) = %.18e\n", x, y);
return 0;
}

I tried
gcc –Wall –I/Users/roberto/Desktop/gsl_universal_1.14/include –L/Users/roberto/Desktop/gsl_universal_1.14/libs/ –lgsl sample.c –o sample

but it can't find gsl_sf_bessel.h. If I #include instead, gcc can't find some other headers. If I create gsl directories inside include/ and libs/, then gcc complains that their's no lgsl library… what I am doing wrong? (thank you in advace!)

Thank in advance.

mkdir temp_install
DESTDIR=`pwd`/temp_install make install


Thanks for providing the precompiled binaries! I originally compiled gsl 1.14 sources for my mac OSX 10.6 to link with my XCode 3.2 project but only the libgsl.a and libgslblas.a where made; and linking to them was not enough to run gsl_randist functions (even with the proper header files set in build options). ( I would get a xxx$non_lazy_ptr symbol not defined error)…
but with your precompiled libgsl.a and librandist.a added to the project things work perfectly!

Thanks again! I'll have to learn how to compile all the libraries from source.
Cheers!

Thanks for any advice!

I briefly played with building a shared library, and it looks like it isn't straightforward. If you set '--enable-shared' in the configure flags, it will still only compile the static library unless it's for the native architecture. From the output of configure, it looks like libtool is balking at the cross-compile.

I'm not doing a 'make install', because I don't want it putting stuff into the system directories. I think it safer to just to manually copy the library and includes where you want them, then statically link the '.a' file by dragging it into the libraries section of the project in XCode, and put the GSL include directory in the path.

As for the ppc64—it looks like they might have pulled support for cross-compiling ppc64 code from Snow Leopard.
