Hi Karim,

This probably just means that you don’t have the directories: /sw/local/lib and /opt/local/lib, which is total normal provided that you don’t have MacPorts or Fink installed. I just included them to cover all bases so to speak. Free free to delete those includes in your settings.

Cheers,

“Have your project in RELEASE mode won’t work (thanks for point that out Paul).”

Ok, I’ve MANAGED TO BUILD THE PROJECT IN RELEASE.

In the project, like you did, click get info->build.

Now, in the configuration, click in release and repeat the process that you’ve made for the configuration debug and that’s it.

Cheers

In case you install gsl in a different location, (mine was ~/sw/), you can use in terminal this commands to find the directory you need to put library and include:

gsl-config –libs
gsl-config –cflags

cheers and thanks for your posting

The problem is gcc cannot find the location of the library. Check that the /usr/local/lib stage, make sure there are no typos. Also verify that you actually installed libgsl in the location you are pointing to. How did you install gsl?

Another idea. Make sure that you are compiling the settings you edited. For example, if you edited the ‘debug’ setting make sure you are not compiling in ‘release’ mode.

Good luck.

OK – I think I have solved it, or at least, I have this working.

I install GSL (for 32 bits) with:

./configure –disable-shared
make
sudo make install

Then in Xcode, with the release settings, I go to the Architecture item and select only i386 (you should remove ppc).

Normally this should work.

Hi Gauillaume,

I don’t know how to do this, if anybody has some insight please share! But I guess is requires bundling a build of GSL with the application. I have never needed to distributed an app that links with external libraries before. I would normally just share my xcode project and assume the user has installed GSL. Would be very useful for the future to solve this problem.
