mathgl doesn't pick up gsl

[annacegu@…]

I am compiling a C++ program that uses mathgl, and I am getting the following error:

/opt/local/include/mgl2/datac_cf.h:30:8: error: definition of type 'gsl_matrix' conflicts with typedef of the same name
struct gsl_matrix;
       ^
/opt/local/include/gsl/gsl_matrix_double.h:50:3: note: 'gsl_matrix' declared here
} gsl_matrix;

Looking at data_cf.h, it seems like MGL_HAVE_GSL is switched off, so mathgl is not picking up GSL headers.

In the future, please use WikiFormatting and Cc the port maintainers (port info --maintainers mathgl), if any.

O.K.: A few things:

1) mathgl has since been upgraded to version 2.3.4.

2) Indeed, the cmake switches for gsl and hdf5 needed to be added.

3) As I was already running 2.3.4 locally, I accidentally rev-bumped to @2.3.4_1. Please use Portfile-mathgl.2.diff​ which gives @2.3.4_0.

Also, I'm thinking some may want qt4 or qt5 variants.

Well, I moved some option switches from the patch file to the Portfile. Please use Portfile-mathgl.3.diff​ and the updated patch-CMakeLists.txt.diff.

Thanks so much for you help. I tried installing 2.3.4 from macports but the latest I get is 2.3.2_2.

How do I get the latest version?

Committed in r146440.

annacegu: wait for about an hour, then run selfupdate again.

Bizarre. The changes in Portfile-mathgl.3.diff​ did not reflect the OpenMP and threads options. Fixed in Portfile-mathgl.4.diff.
