The siril project that uses libgsl fails to build on FreeBSD 11:
/usr/local/lib/libgsl.so: undefined reference to `cblas_zher2k'
/usr/local/lib/libgsl.so: undefined reference to `cblas_dtrsm'
Log:
http://beefy9.nyi.freebsd.org/data/114amd64-default/552369/logs/siril-0.99.6.log
libgsl.so doesn't get linked to libgslcblas.so and has unresolved
symbols cblas_* that are defined in libgslcblas.so. .pc file reports
both libraries, but libgsl.so also needs to be linked with libgslcblas.so
You need to add -lgslcblas when you link libgsl.so
gsl-2.6
