Compiling GCC on HP-UX 10.20 - Gpc

21 Jan 2000


      I started this thread last week when I reported the following errors (see
below) when compiling gcc-2.52.2-gpc-19991030 on HP-UX 10.20.
There had been a series of discussions on how to compile GCC  (without GPC)
on HP.
I try to summarize the issues here.
1.	you need GBU binutils to get the assemler (as); HPÂ’s as seemed not
working well in building GCC
2.	GNU linker (ld), which is a part from GNU binutuils, could not be
built. A poster (in comp.sys.hp.hpux) commented on building GNU ld on HP
below.
    	Â“You can't -- it's not supported. Reason: HP's odd binary
format.Â”
3.	Now even if you have GNU Â“asÂ” and HPÂ’s Â“asÂ” on your HP box, and you
have GNU Â“asÂ” before HP Â“asÂ” in your $PATH, GCC compilation cannot be
guaranteed to use GNU Â“asÂ”. One trick a poster (in gpc.gnu.de) had suggested
is to soft-link GNU Â“asÂ” to GCCÂ’s build directory. This same trick was also
suggested by another poster in in comp.sys.hp.hpux.
4.	HPÂ’s sed was buggy in that it put time stamps onto some files,
making the build to complain. The resolution was two fold : get a patch from
HP to patch HPÂ’s sed, or get GNU sed.
5.	GNU autoconf may be necessary; although I did hack a Makefile to get
rid of the Â“autoheader not foundÂ” error without having GNU autoconf
installed. But lately I just install GNU autoconf to get rid of the trouble.
6.	A script suggested by a poster (in comp.sys.hp.hpux) help in the
building of GCC-2.95.2. I modified it a bit to add comment and add
log-files. See the scripted attached at the end of this message.
I have succeeded in build GCC-2.95.2 (without GPC) using this script (and
the pre-requsites : autoconf, gnu sed, gnu as).
Yet I got the same errors (attached at the end) using the same script for
GCC-2.95.2-plus-GPC-19991030.
So, it seemed to be a GPC bug when comparing the two builds (GCC built OK;
GCC-GPC built failed).
I hope someone could reproduce the problem on their HP-UX, just to rule out
error due to my inexperience on HP-UX.
Thanks a lot for your attention.
