Hi again Brian,
I think when compiling ANSI C on HPPA, one should use /opt/ansic/bin/cc
instead of /opt/aCC/bin/aCC. What happens if you perform the configure
step again, but this time with the additional argument 'CC=cc'? Obviously
'cc' or a symlink to it will have to be in your PATH.
If that fixes it then I suppose 'configure' should be taught to prefer
'cc' over 'aCC' on HPUX somehow. If that doesn't fix it, then read on...
I too had a look through 'man cc' and I too didn't see any options that
would make the compiler be more tolerant of this specific header bug
(well, 'header non-ANSI-ness', at any rate). 'cc -Ae' seems to be as
permissive as it gets with respect to bitfields.
Our copy of /usr/include/netinet/tcp.h has the same bug as yours, but it
seems that at least on our box, 'cc' can compile such code regardless.
I made a test program whose source is below, which compiles and runs on
our HPPA with all of the following compiler command lines:
# LP64, ANSI + HPUX
cc -Ae +DA2.0W -o test test.c
# ILP32, ANSI + HPUX
cc -Ae -o test test.c
# LP64, ANSI only
cc -Aa +DA2.0W -o test test.c
# ILP32, ANSI only
cc -Aa -o test test.c
# LP64, default
cc +DA2.0W -o test test.c
# ILP32, default
cc -o test test.c
Does it compile on your machine using 'cc', too? What about with your aCC?
What versions of these tools do you have, especially /opt/ansic/lbin/ccom
which is the real C compiler (cc is just the driver, same setup as GCC).
On our box, the command '/opt/ansic/lbin/ccom -V' outputs:
ccom: HP92453-01 B.11.11.29484.GP HP C Compiler
Sidenote: I wasn't able to test with aCC - it is suddenly complaining
about missing 'flexlm' license files and I have no idea when it broke or
why... <sigh>. But I've never seen aCC sing and dance in the way that GCC
can; the most I've managed was a croak and an ungainly shuffle ;-)
FWIW I find it best to just turn HP-UX into a GNU/HP-UX system - mostly
GNU userland, but HP-supplied kernel, libc and init. Works much better.
Hope this helps,
