Hello everyone!

I've just found this message from Uros in the mailing list archive:

Quoted 9 lines

I am trying to compile strace under 2.4.0-test6 and I missing symbols for PT_K_B0, PT_K_AR_PFS, PT_K_AR_UNAT, PT_K_AR_RNAT, PT_K_AR_BSPSTORE, PT_K_PR and PT_CR_IFS. I have
sucessfully compiled the same source under 2.3.99-pre6 kernel headers.

Symbol PT_CR_IFS was replaced with PT_CFM; this is a problem with strace source. However, the other symbols disappeared from ptrace_offsets.h. I don't recall any patches against ptrace interface lately. Is this a lossage in kernel headers?

Unfortunately, I haven't found any answeres to this post.

This problem seems to be back with strace 4.3 and kernel 2.4.3. In this case, which one should be fixed??

Thanks!!

Use the strace source from the ia64_0 branch on
cvs.strace.sourceforge.net.

Use the strace source from the ia64_0 branch on
cvs.strace.sourceforge.net.

I've been using it for some time, but it is not up to date with the latest strace release (4.3). Anyway, your answer means that the problem is probably with strace itself. Attached is a patch I've used to build it.

Thanks!!
