Building on OS X: Undefined symbols ___emutls_v.prng_state and ___emutls_v.prng_state_data
Trying to build qemu on my system fails during linking with the error:
Undefined symbols for architecture x86_64:
"___emutls_v.prng_state", referenced from:
_main in region-test.o
__GLOBAL__sub_I_65535_0_region_test.c in region-test.o
"___emutls_v.prng_state_data", referenced from:
_main in region-test.o
__GLOBAL__sub_I_65535_0_region_test.c in region-test.o
My setup:
OS: OS X 10.10.3, 64bit
gcc: 5.1.0
clang: 6.1.0
configure command:
configure --prefix="$HOME/local" --cc=clang --host-cc=clang --cxx=clang++
It makes no difference whether I try to build in the source directory or somewhere else.
It is the same for qemu release 2.3.0 and qemu git@f8340b360b9bc29d48716ba8aca79df2b9544979.
Now this is clearly happening in the pixman submodule, but it does not seem to be a pixman issue, as I can clone git://anongit.freedesktop.org/pixman @cf086d4949092861dc3729465a3881d229cc1060 and build it without any errors with just :
configure --prefix="$HOME/local"
make
It also works with
configure --prefix="$HOME/local" CC=clang CXX=clang++
make
although then OpenMP is disabled.
Also, running
nm qemu/pixman/test/utils.o
gives me (amongst other stuff):
0000000000000020 C ___emutls_v.prng_state
0000000000000020 C ___emutls_v.prng_state_data
So the symbols are actually there, it's really just linking that fails.

I build on OSX 10.10.3 with that clang version, but I build with
the system pixman (in /opt/X11 and presumably part of the optional
X11 OSX download), so I guess that's the difference in our setups
here.
I tried building having configured --without-system-pixman,
but that seems to fail to compile much earlier than your error:
make[3]: *** No rule to make target `pixman-combine.h.template',
needed by `pixman-combine32.h'. Stop.
-- PMM
I have XQuartz 2.7.7 installed and there is no pixman in /opt/X11/bin.
It's /opt/X11/lib/libpixman-1.dylib and /opt/X11/include/pixman-1/ for me, but yes, it's possible I've got that from somewhere other than XQuartz.
Ah well, I only have the "normal" PATH set, not library or include path.
But I managed to build qemu now by just building pixman separately.
According to comment #4, the build finally worked, so I'm closing this ticket now.
