Problems with gcc 2.95.2 build on HP-UX 10.20/11.00

[Richard Lloyd]

I've just finally managed to build gcc 2.95.2 on HP-UX 10.20 and 11.00
(Series 700 workstation) and came across various problems you might
like to look into for the next release:

* "make bootstrap" fails during the stage2 re-build because gcc-built
  .o files are re-linked with HP's cc (giving an "__main not found"
  error). "make" and "make install" (which doesn't do the extra
  stages) work OK though. I have set CC=cc and CFLAGS to " " to
  build the first page ("stage0"?) with the native HP-UX cc.
  Unfortunately, I can't remember exactly which source file it
  falls over on (takes about 3 hours to find it out because I have
  to rebuild from scratch to see it !).

* "make clean" doesn't seem to delete all the binaries/objects that
  are built. Stuff not cleaned included the whole of the hppa* tree
  (aka $(target_alias)), gcc/fixinc/*.o, gcc/fixinc/fixincl and
  gcc/fixincl.

* Many installed files/directories do not have world-read permissions,
  rendering them inacessible to anyone but the user that performed the
  installation. My solution was to chmod a+r all non-soft-links in
  the install tree.

* Many installed files/directories have "old" timestamps (i.e. they are
  mv'ed/cpio'ed from the source tree), which causes problems when
  trying to determine exactly which files have been installed
  (we use timestamps to find out the installed files, so we can
  package them up in a binary depot for HP-UX). My solution was to
  touch all non-soft-links in the install tree.

* Why is CFLAGS set to -g in gcc/Makefile.in ? Shouldn't the configure
  system pass this via @CFLAGS@ ? Similarly, I don't understand why
  CFLAGS = -g in gcc/cp/Makefile.in either.

* INCLUDES in gcc/Makefile.in needed -I$(srcdir)/cp/inc adding because
  some of the files in there are used during the build.

* It appears that fixinc.sh can be called without having built fixincl
  (in the gcc dir, not the gcc/fixinc dir) first, which causes it
  to fail. A dependency in gcc/Makefile.in is needed to resolve this.

* XCXXINCLUDES in libstdc++/configure.in needs
  $(srcdir)/$(TO_TOPDIR)../gcc/cp/inc adding because some files in there
  are used.

* libstdc++/cmath has an abs() definition clash with HP-UX's <math.h>
  I had to put #ifndef __hpux...#endif around any attempts in cmath
  to declare abs().

* texinfo shipped is version 3.12, but the latest release is 4.0.
  Does texinfo really need to be shipped with gcc though ? It might
  be better to tell users to get and install it separately.

I can supply more details on any of these problems (all of which -
apart from "make bootstrap" - I've fixed in various ways) if required
[please reply to me directly as well as any mailing list] - you can
check out our HP-UX port of gcc 2.95.2 here:

On a slightly separate note, are there plans to release a new binutils
to go with the gcc 2.9X series ? I can see that there's active
development going on here:

ftp://sourceware.cygnus.com/pub/binutils/snapshots/

but the last "official" GNU release was 2.9.1 way back in May 1998 !
The Cygnus gas apparently supports PA-RISC 2.0, which is why I'm keen
to see a new official GNU release of binutils :-)
