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

I don’t think so, but it looks like you can fix it by just removing
the offending if statement. It’s obviously broken for the case when
you have neither of HAVE_PSELECT, HAVE_SELECT.

Thanks.
Success! I commented out c++test/server.cc lines 756 and 757, and the
build completed successfully.
Who knows if there will be ill effects in some case sometime in the
future, but seems to work for my purposes for now.
Thanks,
Matthew

err... c++tools/server.cc, not c++test/server.cc.
