I'm getting following error, trying to use installation of gsl in non-standard location so no header in /usr/include ... C_INCLUDE_PATH, CPLUS_INCLUDE_PATH is set to this location, any other env vars to set? thanks

The configurator runs pkg-config to extract the path to the gsl include directory. You may have to install and/or configure pkg-config for that purpose. Note that gsl-ocaml needs access to GSL header files for automatic code generation.

thanks for your quick reply. pkg-config is installed, here is gsl.pc seems as if the includedir is not making it to opam… any suggestions?

circsfw@bluehive:/software/gsl/2.4/lib/pkgconfig>cat gsl.pc prefix=/software/gsl/2.4 exec_prefix=/software/gsl/2.4 libdir=/software/gsl/2.4/lib includedir=/software/gsl/2.4/include GSL_CBLAS_LIB=-lgslcblas

circsfw@bluehive:/software/opam/b1/system/build/gsl.1.21.0>pkg-config --variable=includedir gsl /software/gsl/2.4/include
