According to comment #4, the build finally worked, so I'm closing this
ticket now.

Title:
Building on OS X: Undefined symbols ___emutls_v.prng_state and
___emutls_v.prng_state_data
Status in QEMU:
Won't Fix
Bug description:
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.
