Subject: Building GPC with GCC-3.2.1 on Darwin
Date: 24 Dec 2002, 19:47:18

Here is a first report of my attempt to build GPC-20021128 with the 
GCC-3.2.1 backend on Mac OS X "Darwin".  The GPC build is on a 1.1 GB 
450 MHz PowerMac G4 running Mac OS X 10.2.

Note: I am also trying to build GPC with an Apple-patched GCC backend 
(named "GCC3-1151"), but I will report about that separately.


P r o b l e m   1

During Configure, conftest crashes, but the Configure process happily 
continues. This is not a GPC problem. The crash also appears if I try 
to build GCC-3.2.1 (without GPC).

The file "builtin-attrs.def" causes problems. This is not a GPC problem 
either: same problems if I try to build GCC (without GPC). Being a C 
ignoramus, I simply commented away the offending lines (in order to at 
least continue the build process).

A stament in the file stmt.c" causes problems.

/Users/adriaan/gpcx/gcc/stmt.c:5170:21: attempt to use poisoned "calloc"

The C source reads:

   if (size > 0 && size < 600000
       /* We deliberately use calloc here, not cmalloc, so that we can 
suppress
	 this optimization if we don't have enough memory rather than
	 aborting, as xmalloc would do.  */
       && (cases_seen =
	  (unsigned char *) really_call_calloc (bytes_needed, 1)) != NULL)

  Being a C ignoramus, I changed "really_call_calloc" into "xcalloc" (to 
at least continue the build process).



P r o b l e m   4

The next problem seems to be GPC related. I guess that the GPC experts 
will be able to help here. The build process ends with the statement:

cpp-precomp: could not open 
'RTS_VERSION_CHECK="__GPC_RTS_VERSION_20021128__"'

gcc -o p/util.o -c -DIN_GCC    -g -O2 -W -Wall -Wwrite-strings

I can send in more information, make and configure files, etcetera.
