TEMU-1.0, ‘fastcall’ attribute ignored

[Congcong]

Hi all

i am using ubuntu 10.04 x64 server

when i compiled temu-1.0, it displayed many warnings about

../taintcheck.h:149: warning: `fastcall' attribute ignored

../taintcheck.h:150: warning: `fastcall' attribute ignored

../taintcheck.h:153: warning: `fastcall' attribute ignored

../taintcheck.h:198: warning: `fastcall' attribute ignored

../taintcheck.h:215: warning: `fastcall' attribute ignored

../taintcheck.h:218: warning: `fastcall' attribute ignored

when i try to run temu, it always crash and displays

(qemu) ./winxp.sh: line 8: 12172 Segmentation fault      /home/zongnan/bitblaze/temu-1.0/tracecap/temu -snapshot -net nic,vlan=0 -net tap,vlan=0,script=/etc/qemu-ifup -smb /home/zongnan/bitblaze/share -monitor stdio /home/zongnan/bitblaze/winxp.img

however, when i use it on 32 bit system, i have never came across this problem, so could anyone please tell me what i should proceed?

Though the volume of them is a little annoying, these warnings are not
the cause of the problem. In fact the default calling convention for
64-bit Linux corresponds to what's called "fastcall" on 32-bit. You
can remove the attributes if you don't like seeing the warnings.

This crash has a different cause, which I discussed in more detail in
an old message that included a patch:

https://groups.google.com/forum/?fromgroups=#!topic/bitblaze-users/3_9Zqamg7Bk

The fix is also included in the build instructions I sent to the list
a few minutes ago.

Hope this helps,
