Subject: compiling gcc on 386BSD

Hi Daniel,
Julian forwards all his gcc mail to me, as I'm the one that has been
handling gcc on ref.tfs.com.

The make for gcc 2.3.3 progresses fine until "enquire.c" is compiled to
"enquire". Then enquire runs and gets a "loss of precision trap", and
the make aborts.
That is pretty normal for 386BSD.
The TROUBLESHOOTING section of enquire.c sez to compile arithmetic
traps disabled.....The problem is that I can find nothing in *any* of
the documentation telling me how to compile without traps!
You can try adding:
#include <signal.h>
void
norm_signal ()
{
fprintf (stderr, "You got a FPU trap\n");
}
and then inside main:
signal (SIGFPE, norm_signal);
I don't think it will help though. The problems are in libc.a.
I've consulted the 5 top local guru's here at NDSU, Fargo, ND, but none
of them has any idea how to do it. I had already tried all the
suggestions they had, and searched the doc's quite completely.
Can you help?
A little.
I am running a Gateway2000 EISA 486DX system with a kernel built from
your SCSI code. The OS is (of course) 386BSD, and the compiler I am
trying to build is gcc 2.3.3

Here's my packed answer...
The only problem in compiling gcc-2.3.3 on a 386BSD machine is with
enquire. Enquire first refuses to compile and later generates inaccurate
values for DBL_MIN and DBL_MAX.
The complete compilation require about 50MB of disk space.
I have no solution, but am well aware of the enquire problems. If your
goal is to install gcc-2.3.3 as fast as possible you can simply ignore
all enquire problems. You do:
0. tar xvfz gcc-2.3.3.tar.Z; cd gcc-2.3.3
1. ./configure i386--bsd --with-gnu-ld
2. make LANGUAGES=c (ignore the problem that enquire doesn't compile, it
is the last target in the make)
3. make stage1
4. make "CC=./stage1/xgcc -B./stage1/" CFLAGS="-g -O" (ignore the error code
4 from enquire (four constants are imprecise)
5. make stage2 (you can now remove the stage1 directory, if you wish)
6. make "CC=./stage2/xgcc -B./stage2/" CFLAGS="-g -O" (ignore the error code
4 from enquire (four constants are imprecise)
7. make compare
8. make install
9. edit /usr/local/lib/gcc-lib/i386--bsd/2.3.3/include/float.h to correct
for the enquire problems.
DBL_MIN should end in 14
DBL_MAX should end in 57
Also you can replace your malloc routines in libc.a (before compiling gcc2),
with the GNU malloc routines. This makes gcc2 and many other programs need
much less RAM. If you don't know how to do this it i safer to keep the
original malloc routines.
