compiling gcc-4.0.2 on solaris 9

[Douglas B. Jones]

(NOTE: I originally posted this to gcc-help, but only got
one response that the sender said they had posted a similar
posting a while back and got no responses. So, I am reposting
the below to gcc in hopes that this might be a better place
to post this question.)

I am on:

SunOS hostname 5.9 Generic_118558-14 sun4u sparc SUNW,Sun-Blade-1500.
I try to do a bootstrap with the following using gnu make 3.80:

mkdir objectdir;cd objectdir
CC="cc -xildoff -xarch=v9"
export CC
../gcc-4.0.2/configure
gmake bootstrap

I get the following errors:

Why are you choosing those flags?

Just do CC=cc, you will get both a 32-bit and a 64-bit compiler.  What
seems to be happening is that the build process assumes that the first
libiberty you get (the one built with the native compiler) is 32-bit code.

Probably because they are advertised on:
http://gcc.gnu.org/install/specific.html#sparc64-x-solaris2

Douglas has simply mixed 32-bit and 64-bit configuration.

For the 32-bit compiler (sparc-sun-solaris2.9), CC=cc is fine.
For the 64-bit compiler (sparc64-sun-solaris2.9), CC="cc -xarch=v9" is fine.

This seems error-prone; maybe more warnings need to be added to the
installation note.

Also, sparc-sun-solaris2.9 doesn't mean "32-bit compiler", it means
"build both compilers, defaulting to 32 bits".

No, the compiler is purely 32-bit, only the libraries are of both flavors.

We are using the term in a differnent way, it appears.

Although the compiler's executable is composed of 32-bit code, it can
generate 32 or 64 bit code, which is what I meant by "both compilers".

Ah!  Indeed, but you're going to further confuse the readers. :-)

I think the best terminology is "32-bit multilib compiler" for 
sparc-sun-solaris and "64-bit multilib compiler" for sparc64-sun-solaris.

Thanks to everyone for the information below. I have change the
CC to cc only. So, now the script is:

CC=cc
export CC
../gcc-4.0.2/configure
gmake bootstrap

and I get the errors:

This is all somewhat after the line of "Comparing stage2 and stage3 of the compiler".

Also, the ask why I was using the flags I was. The only reference I found to sparc
where the sparcv9-*-solaris2* which sent me to sparc64-*-solaris2* on install/specific.
html. Should I have been looking somewhere else?

Thanks everyone for the help you have given to one who is not too familiar with
compiler work. Thanks!

Do not export CC and do not use a relative path:
CC=cc $absolute_path/configure ...

RE: compiling gcc-4.0.2 on solaris 9

[Douglas B. Jones]

Ok, here is my script (note I am in a directory with only the
script below when I execute the script below):

CC=cc /export/home/src/net/gnu/gcc-4.0.2/configure
gmake bootstrap>make_err 2>&1

I get the exact same errors (at least as far as I see).

Also, I had actually looked at the two links below (for Solaris), but
they appeared to be more from earlier than Solaris 9 and for the most
part for earlier versions of the compiler (3.x series).

Once again, I appreciate all the help you all give! Thanks!

The target libiberty is not supposed to be built with the bootstrap compiler.
Please verify that CC is not set in your environment.

I put:

printenv CC
echo $CC
which cc

in the script and only got output for the which cmd as /opt/SUNWspro/bin/cc.
I even reran the script with CC not set, just to make sure. Thanks!

Hum... let's try the basic checks then:
- what is your configure shell?
- what is your version of GNU make?

Eric Botcazou

RE: compiling gcc-4.0.2 on solaris 9

[Douglas B. Jones]

configure shell: /bin/sh
gnu make: GNU Make 3.80

Although I had #!/bin/sh at the beginning, it was taking my
SHELL as tcsh. I have stuck in (via notes) SHELL=/bin/ksh;export SHELL
and I am rebuilding it right now. Thanks!
