This is with code out of the git repo, I think the last release behaves
the same on this platform but haven't tested it much.
Firstly, a default build is unable to resume detached sessions, showing
WriteMessage: Bad file number
Compiling instead with -DNAMEDPIPE does get around this however.
Regardless of figuring out a fix for the above error, does anyone have
hints as to how the the configure script might be improved to detect
the need for -DNAMEDPIPE on this OS?
Secondly, I'm not getting the load average feature compiled in without
explicitly adding -DLOADAV, but that initially doesn't compile because I
have no definition of the LOADAV_AVENRUN macro. I'm able to compile by
changing line 303 of loadav.c to
nl[0].n_name = "avenrun";
A bit of a closer look at the config.log showed me what looks to be the
problem, here's the excerpt:
configure:5573: checking for nlist declaration...
configure:5593: checking for avenrun symbol...
configure:5635: cc -o conftest -g -L/usr/local/lib/hpux32 conftest.c -lncurses
-lelf >&5
ld: Type mismatch for symbol "nl"; resolving OBJECT symbol (in file conftest.o)
to FUNC symbol (in file /usr/local/lib/hpux32/libncurses.so)
1 warnings.
configure:5635: $? = 0
configure:5635: ./conftest
./configure[20]: 26016 Memory fault(coredump)
configure:5635: $? = 139
configure: program exited with status 139
I'm not entirely sure that my ncurses is completely normal, since it's
from a binary package... it does seem a bit odd for ncurses to have a
two-letter global, but the one in screen is easily enough changed.
