Hello there,

I am hoping someone can give me some pointers installing gcc-2.7.2.1 onto an
IBM RS/6000 running AIX v4.2.

I ran 'configure' with no options (results as follows):

--->
[piglet]/usr/local/src/gcc-2.7.2.1) ./configure
This appears to be a rs6000-ibm-aix4.2.0.0 system.
Using `./config/rs6000/rs6000.c' to output insns.
Using `./config/rs6000/rs6000.md' as machine description file.
Using `./config/rs6000/aix41.h' as target machine macro file.
Using `./config/rs6000/xm-rs6000.h' as host machine macro file.
Merged rs6000/x-aix31.
Merged rs6000/t-newas.
Merged c++ fragment(s).
Created `./Makefile'.
Merged rs6000/x-aix31.
Merged rs6000/t-newas.
Created `cp/Makefile'.
Links are now set up to build a native compiler for rs6000-ibm-aix4.2.0.0.

But 'make LANGUAGES=c' stopped at the following point:
--->
        cc  -DIN_GCC   -g     -I. -I. -I./config   -DTARGET_MACHINE=\"rs6000-ibm-aix4.2.0.0\" -DUSE_COLLECT2  -c `echo ./collect2.c | sed 's,^\./,,'`
"collect2.c", line 2669.28: 1506-045 (S) Undeclared identifier ARMAG.
"collect2.c", line 2675.20: 1506-022 (S) ar_name not a member of the struct or union ah.
"collect2.c", line 2728.8: 1506-022 (S) ar_name not a member of the struct or union ah.
make: The error code from the last command is 1.

After a bit of detective work, I found that ARTYPE is defined in 
/usr/include/ldfcn.h as 0177545 but only if either of PORTAR, PORT5AR or AIXV3AR
is defined.  If not, ARTYPE appears to be defined as ARMAG which has no further
definitions (that I can find) and thus the above error.

I modified the Makefile to add "-DPORTAR" for collect2.c and all proceeded well
until the following point:

        mv tmplibgcc2.a libgcc2.a
        if [ x != xlibgcc1-asm.a ];  then true;  else rm -f ;  fi
        if [ x != xlibgcc1-asm.a ];  then true;  else  make GCC_FOR_TARGET="./xgcc -B./"  AR="ar" AR_FLAGS="rc" CC="cc" CFLAGS="-g"  HOST_PREFIX="" HOST_PREFIX_1="loser-"  LIBGCC2_CFLAGS="-O2   -DIN_GCC   -g -I./include  -g1  -msoft-float -mcpu=common" ;  fi
        rm -rf tmplibgcc.a tmpcopy
        mkdir tmpcopy
        if [ x != x ];  then (cd tmpcopy; ar x ../);  else true;  fi
        (cd tmpcopy; ar x ../libgcc2.a)
        (cd tmpcopy; ar rc ../tmplibgcc.a *.o)
        rm -rf libgcc2.a tmpcopy
        if [ -f /usr/bin/ranlib -o -f /bin/ranlib ] ; then ranlib tmplibgcc.a; else true; fi
        if [ -d soft-float/common ]; then true; else mkdir soft-float/common; fi
        mv tmplibgcc.a soft-float/common/libgcc.a
        touch stmp-multilib
        rm -f milli.exp
        cp ./config/rs6000/milli.exp ./milli.exp
        ./xgcc -B./  -DIN_GCC   -g -I./include  enquire.o -o enquire
collect2: /lib/crt0.o: not a COFF file
make: The error code from the last command is 1

I don't know what to do from this point - any suggestions would be greatly
welcomed.

Many thanks in advance.
