I stumbled over an interesting problem where the emscripten-fastcomp build
process thinks it is running on OSX10.1, but this is OSX10.10:
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
The entire command line is below (note the -mmacosx-version-min=10.1). The
problem seems to be in the Options.inc file, but I haven't dug yet into
clangs build files enough.
tools/clang/include/clang/Driver/Options.inc:OPTION(prefix_1,
"mmacosx-version-min=", mmacosx_version_min_EQ, Joined, m_Group, INVALID,
0, 0, 0, 0)
Anybody had the same problem and found a fix?
Here's the linker command line that fails:
