# NOTE:
# The libgsl package on Solaris is getting GSL CBLAS routines from
# libsunperf.so. Programs wishing to use this functionality should use the
# /usr/include/sunperf.h header file for the associated definitions and
# function prototypes and link against -lsunperf.
#
# To retain compatibility with libgsl on other platforms, and to require
# no changes to FOSS software being ported to Solaris, the libgsl package
# manifest will also include the /usr/include/gsl/gsl_cblas.h header file
# and provide links from /usr/lib/libgslcblas.so and
# /usr/lib/$(MACH64)/libgslcblas.so to their equivalent libsunperf.so
# library files.

# By default, tests in each GSL sub-directory are linked statically against
# a set of .la files. We don't deliver those in the GSL package, so we
# adjust all the tests to link against the dynamic GSL library instead.
