Fails to compile:
/tmp/cc54N2JC.o: In function `main':
/home/dave/src/xfstests-dev/src/diotest.c:120: undefined reference to
`pthread_create'
/home/dave/src/xfstests-dev/src/diotest.c:135: undefined reference to
`pthread_join'
It needs to be linked against libpthread, I think, so that needs to
be added to the LLDLIBS line, and the appropriate autoconf detection
macros added. You shoul dbe able to just copy the some
detection/infrastructure macros across from xfsprogs...
Cheers,
Dave.
