INSTALLING G++ ON THE SUN 386i
------------------------------
THESE PATCHES ARE FOR THE 1.35.1- RELEASE!!!!!
Apply these patches. There shouldn't be any *.rej files!
Use config.g++ as usual. Edit the makefile libdir spec, etc. Make sure to
define "-DNO_GNU_LD" to the compiling of gcc.c. Also add "-lld" to CLIB.
Collect needs this. Do a make.
The make will fail on ld++. You have two options:
1. Fix ld++ => stop reading this file and post your fixes.
2. Do a "make collect". Continue reading.
- "make install"
- Copy collect to the same directory where g++ will go.
- Create libg++ (it's a separate distribution).
Now it should work! Note that dbx seems to have problems with the executables
so there is no debugging available until someone fixes gdb. Also note that
all linking is static since the G++ crt0 doesn't support dynamic linking. Yet...
Furthermore, the incremental linking facility is not supported.
Some of the tests in libg++ get failed assertions. In a way this is good,
because that means that this port may help uncover possible compiler bugs.
Unfortunately, I haven't had the time to look at it yet. With the release
of these patches I hope that someone else may have time to do it. It's
important to fix all bugs quickly.
I *have* compiled a rather large software package which uses SunView and
interfaces to C and FORTRAN with G++ on the Sun386i with no problems.
Looks pretty stable to me... It's certainly production quality.
Questions will be answered, time permitting.

I forgot to mention that the SUN assembler thinks that you shouldn't use
long file names, like cplus-parse.tab.c. How's that for 10 years backwards
development?
Note the commands for compiling this file. Then rename it to e.g. "c.c",
compile it the same way, and rename c.o to cplus-parse-tab.o. That's
an easy temporary fix until we can use all the GNU tools, i.e. GAS.
