Sorry I haven't figured out the diff files just yet.
llvm-3.9 build fails at 12% and then at 98% with error strnlen function
not found
to fix:
in this file
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.9/llvm-3.9/work/trunk/lib/ObjectYAML/MachOYAML.cpp
and in this file
/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.9/llvm-3.9/work/trunk/tools/obj2yaml/macho2yaml.cpp
add this replacement function after <string.h> and build succeeds
(found an example in the cctools patches):
{{{
static size_t
strnlen(const char *s, size_t maxlen)
{
size_t len;
for (len = 0; len < maxlen; len++, s++) {
if (!*s)
break;
}
return (len);
}
}}}
