>Description:
erlang-runtime-16.b.01 does not build the wx application when using clang since
otp_src_R16B01/lib/wx/configure:5137 states
CXXFLAGS="$CXXFLAGS $CFLAGS $CPPFLAGS"
which makes '-std=gnu89' (from USE_CSTD in Makefile) end up in the c++ command.
clang fails:
error: invalid argument '-std=gnu89' not allowed with 'C++/ObjC++'
during configure of lib/wx. (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
