This archive contains the following pre-built
binaries: 
gcc-2.7.2.2
g77-0.5.20
libg++-2.7.2

built on and for the i386-next-nextstep3 platform.  includes drivers
for both 
i386-next-nextstep3
and
m68k-next-nexstep3 (a cross-compiler)
targets.


NOTES

These have been built for and tested on NEXTSTEP 3.3, but may also work
on other versions.  This build will mostly like NOT work on OpenStep 4.0
and later.

The included libraries (libf2c.a and libg++.a) have been stripped to save 
installation space.  This may impeed debugging (using gdb) efforts if you 
are building programs using those libraries.

I may also make a m68k-next-nextstep3 hosted compiler, if there is 
sufficient interest.


INSTALLATION

unpack into /usr/local, and you're done.  Issue the following commands
as root:
cd /usr/local
gnutar xzvf /PathToArchive/gcc.2.7.2.2.I.b.tar.gz

NOTE: you STILL need the nexstep developer
packages installed in order to use this, as it
uses NeXT's supplied C libraries.  Also, in order to use the
m68k-next-nextstep3 cross-compiler, you need the
DeveloperLibs installed for m68k (in addition to i386).

Now if someone ported glibc (GNU libc) to NEXTSTEP, that 
would be something!


The CROSS-COMPILER

It's a little tricky to use the cross-compiler,
as it's usage differs a bit from NeXT's cc compiler.
To produce m68k binaries, envoke gcc as:
gcc -bm68k-next-nextstep3 foo.c

FAT binary NOTE: gcc cannot (easily) create FAT binaries, at least 
not in the same sense of NeXT's cc, ie,
cc -arch m68k -arch i386 foo.c
With gcc, you need to create to separate binaries, and then use
lipo.

Also, the cross-compiler doesn't look in /usr/local/lib
for linking libraries, by default, like the native compiler does.  If
you need to link against items in /usr/local/lib, you'll need to pass
the option -L/usr/local/lib (ie, by adding to CFLAGS or LDFLAGS) to 
the linker (ld).
