Hello,
This may be a bit of stretch given that HP-UX 11.23 (11i v2) is a
bit...aged. But curious if anyone has any thoughts.
I am trying to build GCC 12.1.0 on HP-UX 11.23 on 64-bit PA-RISC.
(hppa64-hp-hpux11.23).
I current have GCC 6.5.0 (by way of HP ANSI C -> GCC 4.7.4 -> GCC 6.5.0)
with GNU binutils 2.38 (to provide as, since the GCC platforms page says
to use gas instead of the HP-UX as).
Stage 1 and Stage 2 appear to succeed. During Stage 3, I receive the
following:
/home/mwilson/build/src/gcc-12.1.0/c++tools/server.cc:756:69: error:
'readers' was not declared in this scope; did you mean 'readv'?
756 | if (active < 0 && sock_fd >= 0 && FD_ISSET (sock_fd, &readers))
| ^~~~~~~
With a bit more context:
$ make

Not sure if this is because HP-UX 11.23's system headers aren't
including something that's necessary (with GCC 6.5.0 I have a C++11
compiler, but I suspect HP-UX 11.23's libc isn't a C++11 stdlib...), or
if this is a solveable problem.
Alternatively, are these c++tools necessary? Can they be excluded from
the build?
My configure command was:
$ /home/mwilson/build/src/gcc-12.1.0/configure \
--prefix=/home/mwilson/bldutils64-gcc12.1.0 \
--enable-languages=c,c++ \
--with-gnu-as --with-as=/home/mwilson/bldutils64-gcc6.5.0/bin/gas \
--without-gnu-ld --with-ld=/usr/bin/ld \
--enable-threads=posix
Thanks,
Matthew
