[Qemu-devel] Help needed! dyngen: Unsupported ELF class

[test test]

Hi,

I am new to QEMU and tried to build qemu 0.9.0.

I did ./configure and then make,  then I got the following error message:

gcc-3.3 -Wall -O2 -g -fno-strict-aliasing -fno-reorder-blocks
-fno-optimize-sibling-calls  -I. -I..
-I/home/xxx/work/qemu/qemu-0.9.0/target-i386

../dyngen -o op.h op.o

What's the problem? Please help!

Thanks in advance!

For better analysis of the problem, I put the result of configure as below:

Is it possible that your gcc-3.3 is an i386 compiler? If so, edit 
config-host.mak and replace "ARCH=x86_64" with ARCH="i386", then 
rebuild.

I tried it, but still got the same error. Any further suggestion?

Thanks,
