(Can not link the wx driver, wx will NOT be useable) When this is fixed (by not including CFLAGS into CXXFLAGS) the wx build failes: /usr/bin/ld: amd64-portbld-freebsd10.0/wxe_impl.o: relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC amd64-portbld-freebsd10.0/wxe_impl.o: could not read symbols: Bad value >How-To-Repeat: build lang/erlang-runtime16 with WX enabled and clang >Fix: --- lib/wx/configure.orig 2013-06-26 23:47:25.000000000 +0000 +++ lib/wx/configure 2013-06-26 23:47:48.000000000 +0000 @@ -5134,7 +5134,7 @@ -CXXFLAGS="$CXXFLAGS $CFLAGS $CPPFLAGS" +CXXFLAGS="$CXXFLAGS -fPIC $CPPFLAGS" CFLAGS="$CFLAGS $CPPFLAGS $C_ONLY_FLAGS" DEBUG_CXXFLAGS="$CXXFLAGS $DEBUG_CFLAGS $CPPFLAGS" >Release-Note: >Audit-Trail: >Unformatted:
