722464 - Build failure on linux x86_64 when building with clang

Status: RESOLVED WORKSFORME

(Core :: Graphics: ImageLib, defect)

Description

[George Wright (:gw280) (needinfo me!)]

If I try to build with clang with the following mozconfig:

CC=clang
CXX=clang++
ac_add_options --enable-debug-symbols
ac_add_options --enable-profiling
mk_add_options MOZ_MAKE_FLAGS="-j8"
mk_add_options MOZ_OBJDIR=./obj-linux-prof

I get the following build error:

/usr/bin/ld.bfd.real: ../../media/libjpeg/simd/jsimd_x86_64.o: relocation R_X86_64_PC32 against symbol `jconst_rgb_ycc_convert_sse2' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld.bfd.real: final link failed: Bad value
clang: error: linker command failed with exit code 1 (use -v to see invocation)

This builds fine if I don't use clang.

Hm.  I've built on Linux x86-64 in the past month and didn't have a problem.  This jpeg code shouldn't have changed since then.

Did you do a clobber build when switching compilers?

Also, what's the output of

  $ yasm --version

?

What clang version are you using?

clang 2.9 in known to not work. I think 3.0 works and I have been using 3.1 (trunk).
