[Qemu-devel] Fail to compile

[Anne et Bertrand]

System : Mandrake9.1PPC, kernel-2.4.23.
Wgereas qemu-0.5.0 compile and run on my system, I can't compile 
anymore qemu-0.5.2 and also the latest CVS :

gcc -Wall -O2 -g -I. -I/home/bertrand/Desktop/qemu/target-i386

Any idea ?

What is your glibc version ?

[Qemu-devel] [BUG] signed 16 bits word load for bigendian targets.

If the LSB is negative, the result is false.

I've applied this patches to 0.5.2 : compiled with success (although a 
little trouble on install : it failed on some directorie in the source 
tree so I had to cd to each one and type make to finish the install). 
Runs well : for the first time I could launch ReactoS and even a kind of 
Knoppix disk image. Thanks !

The patche applied to the cvs tree let syscall.c compile too, but I've 
got an assembly error later in i386-softmmu :
