[Gm2] GM2 on HP-UX 11.11 (PARISC) Status Report

[John O Goyo]

Trying to build GM2 (2006-12-18) on HP-UX B.11.11 PA-RISC 9000/785.
The story so far...

0. I obtained gcc 4.1.1 binaries from HP and the core source
distribution from GNU.

1. I configured, built, and installed gcc 4.1.1 using the configuration 
line below.  The installed binaries can compile and link a C programme 
so I know that I am starting from a sane environment.

CC=gcc CONFIG_SHELL=/opt/OpenSource/bin/bash 
../../src/gcc-4.1.1/configure --prefix=/home/build/bin/gcc 
--exec-prefix=/home/build/bin/gcc --host=hppa2.0-hp-hpux11.11 
--with-gnu-as --with-as=/usr/local/bin/gas --without-gnu-ld 
--with-ld=/usr/ccs/bin/ld --enable-languages=c


2. I added gm2 to the mix.  I first discovered that gcc 4.1.1 on HP-UX 
11.11 does not support dwarf-2.  The option --without-dwarf2 was ignored 
to work so I removed references to dwarf-2 in Make-lang.in.


3. The script tools-src/createUlmSys fails.  I suspect that somewhere in 
my environment, the shell is being changed from bash to something else. 
 I failed to find the place so I moved createUlmSys to 
createUlmSys.orig and replaced the former with the following invocation.
        /opt/OpenSource/bin/bash $(TOOLS-SRC)/createUlmSys.orig $*

The build now succeeds.


3. I tried gmake gm2.paranoid.  The linker seems unable to find any of 
the symbols:

ranlib gm2/gm2-libs/libgm2.a
gcc   -g -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes 
-Wmissing-prototypes     -DHAVE_CONFIG_H  -o stage2/gm2/cc1gm2

   [...lots of symbols...]


4. Nevertheless, I tried installation.  The binaries installed but not 
the libraries.  In particular, I can compile Hello.mod but not link it 
(vide infra).

heap: tst=> cat Hello.mod
MODULE Hello;

FROM StrIO IMPORT WriteString, WriteLn;

BEGIN
  WriteString( "GM2 on HP-UX -- wot the ..." );
  WriteLn
END Hello.

heap: tst=> gm2 -c -I. Hello.mod
heap: tst=> file Hello.*
Hello.mod:      pascal program text
Hello.o:        PA-RISC1.1 relocatable object
heap: tst=> gm2 -o Hello Hello.mod

option.
collect2: ld returned 1 exit status

I am continuing.  Suggestions are more than welcome.

(Sigh)
