>Description:
A few issues with /usr/ports/lang/gnat which creates packages-9.2-release/lang/gnat-2010.tbz
-DWANT_SHAREDLIBS builds libgnala.a, not libgnala.so
gnatmake adds linker options -Wl,rpath and -L
/usr/local/lib/gcc-nat/gcc/i386-portbld-freebsd9.2/4.3.6/adalib/
The trailing / must be removed from command line -L to find -lgnat-2010.
Body unit source file gcc-4_3-branch-src/gcc/ada/i-forbla.adb pragma add undefined dependency to -lgnalasup. Changing to
-pragma Linker_Options ("-lgnalasup");
+pragma Linker_Options ("-lblas");
+pragma Linker_Options ("-llapack");
appears to resolve the dependency issue (attached patch).
LIB_DEPENDS+= blas:${PORTSDIR}/math/blas
LIB_DEPENDS+= lapack:${PORTSDIR}/math/lapack
>How-To-Repeat:
>Fix:
correct linker dependency
