Re: [Openexr-user] command line utilities to join tiled images?

I cannot reproduce the problem on my Linux machine.  After setting
HAVE_PATHREAD and HAVE_POSIX_SEMAPHORES in OpenEXRConfig.h to 0,
I typed "make clean; make; make check", and all tests pass.
(I've tried running "make check" repeatedly, but the program fails
to hang.)

Did you "make clean" after setting HAVE_PTHREAD to 0?
