AIX multilibs pthread support. Unlike Linux, AIX does not provide
weak versions of the pthread symbols when operating in single-threaded
mode. AIX uses gthr-aix.h, which includes gthr-posix.h or gthr-single.h
depending on the -pthread option.
Thank you, this was indeed the problem. I added the needed stubbs in
gthr-single.h and it now compiles fine. Unfortunately there seems to be
something wrong with my installation of ld as linking fails with a large
number of errors of the form:
ld: 0711-252 SEVERE ERROR: File auxiliary symbol entry 1 in object _negdi2_s.o:
Field x_offset contains 4. Valid values are between 4 and -1.
The object name is being substituted.
Unfortunately I have almost no experience with AIX. I'll look for a prebuilt
ld that seems newer than mine to see if this helps the problem.
Thank you for your help.
Luke
