<pre>Trying to build llgo in the llvm/clang 3.8 source tree on x86_64 linux results
in
/usr/bin/ld: error: .libs/go-assert.o: requires dynamic R_X86_64_PC32 reloc
against '__morestack' which may overflow at runtime; recompile with -fPIC
/usr/bin/ld: error: .libs/go-assert-interface.o: requires dynamic R_X86_64_PC32
reloc against '__morestack' which may overflow at runtime; recompile with -fPIC
/usr/bin/ld: error: .libs/go-byte-array-to-string.o: requires dynamic
R_X86_64_PC32 reloc against '__morestack' which may overflow at runtime;
recompile with -fPIC
/usr/bin/ld: error: .libs/go-caller.o: requires dynamic R_X86_64_PC32 reloc
against '__morestack' which may overflow at runtime; recompile with -fPIC
/usr/bin/ld: error: .libs/go-callers.o: requires dynamic R_X86_64_PC32 reloc
against '__morestack' which may overflow at runtime; recompile with -fPIC
[...]
more of the same for other libgo source files follows
[...]
This is with ld = gold; if I switch to bfd ld, the error message becomes much
smaller, but the issue remains:
/usr/bin/ld.bfd: .libs/go-assert.o: relocation R_X86_64_PC32 against undefined
symbol `__morestack' can not be used when making a shared object; recompile
with -fPIC
/usr/bin/ld.bfd: final link failed: Bad value
libgo did get built with -fPIC.</pre>
