[Qemu-devel] Problems encountered while building qemu-0.6.1

[Peter S. Mazinger]

Hello!

1. CFLAGS/LDFLAGS from config-host.mak are overwritten/ignored
2. VL_LDFLAGS/OP_CFLAGS should also "inherit" from config-host.mak
3. Trying to build qemu in an environment, where gcc defaults to -fPIC
fails building op.o/osdep.o/helper.o.
If I disable -fPIC on the complete build, the resulting qemu-* files 
contain text relocations (readelf -d <file>). Due to the fact that they 
are like shared libs, the text relocs should not be present.
4. The files qemu-* (user and sofmmu) are created w/ LDFLAGS=-Wl,-shared
creting ET_DYN/PIE executables. gcc-3.4 and binutils-2.15 support gcc 
-pie/ld -pie, this can be checked by gcc -fpie and ld --help | grep pie
5. building qemu w/ a propolice/ssp patched gcc, op.o creation fails if 
-fstack-protector-all is enabled.

Please CC to me, I am not subscribed, thanks.
