Other than that: About fdopendir, the logs say: checking for fdopendir... no checking whether fdopendir is declared without a macro... yes checking whether fdopendir is declared... (cached) yes So apparently they declare the function but don't implement it. Fortunately, gnulib does the right thing out of the box.
About mknod, the logs say: configure:40991: checking whether mknod can create fifo without root privileges configure:41015: xlc -o conftest -g -D_THREAD_SAFE conftest.c >&5 configure:41015: $? = 0 configure:41015: ./conftest configure:41015: $? = 1 configure: program exited with status 1 You shouldn't be running configure as root; this is dangerous! About ptsname, you say: > FAIL: test-ptsname <- need to kill the test I have no idea why. Someone needs to debug this. Bruno
