Hi, I am not able to build qemu successfully on my gentoo box with gcc 3.4.6.
Heres the build error

Hmm, I'm not having this error although I'm on gentoo as well. It may have
something to do with 32-bit register set, are you on a 32-bit system? I can
only test on 64-bit but I would expect someone in upstream tests things on
32-bit (as this bug would be an upstream bug)

Yup, am on a 32 bit machine, AMD Athlon 2000+ XP to be exact

comment:3 Changed 11 years ago by balrogg@…

It is confirmed by upstream: gentoo's 3.4.6 doesn't build qemu on 32-bit x86. A
gcc developer (Paul Brook) said gentoo's gcc "is broken" and nothing can be done
outside gentoo.

I myself use gcc-3.3.6 which for some reason was the default when I installed

thanks for the info..Will use another version of gcc then
thanks again

  • Status changed from new to closed
  • Resolution set to fixed

Compiled without errors with gcc 3.3.6, marking as resolved
