Re: [Help-gnucap] Compiling for FreeBSD

[alan somers]

The gmake issue isn't too bad.  Lots of software needs gmake when
built on FreeBSD.  The bigger problem is that gnucap requires GCC.
FreeBSD's default compiler is Clang, and GCC is a huge dependency to
bring in.  It would be great if Gnucap would compile with Clang.  The
following patch gets Gnucap to compile, but not link., with Clang.  I
get link errors like this:

(export LD_LIBRARY_PATH=`pwd | sed 's/apps/lib/g'`; `pwd | sed
's/apps/modelgen/g'`/gnucap-modelgen -cc ../d_mos1.model)
