I have made pthreads working under FreeBSD 2.0.5, but there is a couple of
issues:
(1) obj/ directory must be created manually before doing make;
otherwise, the above problem happens. I guess the following line
does not work properly in Makefile
.OBJDIR != if test -d ${.CURDIR}/obj ; then true ; else mkdir ${.CURDIR}/obj ||
exit 1 ; fi ; echo ${.CURDIR}/obj
(2) I do not know why input pipe causes threaded program deadlock:
threaded.xviewer filename # works fine
threaded.xviewer < filename # works fine
cat filename | threaded.xviewer # deadlock on threaded.xviewer
Ctrl-C or Ctrl-Z will kill or stop "cat", but leave "threaded.xviewer"
hanging forever. kill -9 pid can terminate the threaded.xviewer.
Any idea?
