Re: problems compiling gcc under Max OS X

[Dan Allen]

I too am having problems building an Intel gcc 4.3.1 on Mac OS X  
10.5.4 on a standard iMac.  There are many issues.

I grab the gmp-4.2.2 distribution, ./configure, make, and make install  
it to /usr/local.  Everything is great.

ISSUE #1:
I then grab the mpfr-2.3.1 distribution, ./configure it, and the ./ 
configure fails. It says that the ABIs do not match.  config.guess in  
the gmp build gives returns 'core2-apple-darwin9.4.0', while  
config.guess in the mpfr build returns 'i386-apple-darwin9.4.0'.   
Hmm.  Well, core2 is not the same as i386, but they are in some sense  
compatible.  How does one fix this?

ISSUE #2:
There are a lot of places in the configure scripts where you see

   rm: conftest.dSYM: is a directory

Is there an autoconf that fixes this?  rm needs to be rm -rf on Mac OS  
X.  (Is this because of a case-insensitive file system?)

ISSUE #3:
I really wish that these extra dependencies were not there.  I can  
build gcc 4.2.5 without any problems, but requiring gmp and mpfr in  
4.3+ with these hassles is a real pain.  Why can't these be integrated  
into gcc and put into gcclib so builds go smoother?

Thanks for listening.

Take a look at the Makefile for gmp. Look for the line CFLAGS= and  
then when going to configure mpfr use:
configure <whatever options you normally use> CFLAGS="<whatevers  
listed in the make">. This should allow you to build and install  
mpfr. Apparently, theres issues with it's configuration scripts.

This should allow you to get mpfr installed. Let me know if this  
completly solves your issues or if you are still having problems  
getting gcc to compile.

As far as my issue:

I've made a seperate build directory and am still having the same  
issues. Not specifying any parameters gives me an error that gmp/mpfr  
are not found... but I've built and installed them in the default  
location. If you guys have any other suggestions I'm all ears. I  
would perfer not to have to jump to an earlier build...

Could I suggest you install gcc via macports?

While this does mean the resulting executable is in /sw/bin, I find it
works fine.

Glad to have helped. Answering your question drew me to the same  
evaluation and results.

Now the real work begins. ;)

Re: problems compiling gcc under Max OS X

[Dan Allen]

Thanks to Bill Broadley, Robert Fuller, Nicholas Miller, and Chris  
Jefferson for the help.

It appears that my issue #1 is related to the default build of  
gmp-4.2.2.  On my iMac with its Core2 Duo chip, gmp's ./configure  
script builds gmp with -m64 -mtune=k8.  This appears to be the root of  
the problems.  The build should be 32-bit, not 64-bit, and my machine  
does not have an AMD K8 in it!

Starting with gmp-4.2.2,  I found success by doing:

	./configure ABI="32" CFLAGS="-O2"
	make -j4
	sudo make install

Then with mpfr-2.3.1, I found success by doing exactly the same:

	./configure ABI="32" CFLAGS="-O2"
	make -j4
	sudo make install

Then with the folder gcc-4.3-20080710 (the latest GCC snapshot), I did:

	cd gcc-4.3-20080710
	mkdir build
	cd build
	../configure
	make

and voila: gcc-4.3.1 builds!

Perhaps this info can be added to GCC release notes so that others  
which want to build GCC-4.3 can build these required libraries properly.

<soapbox>
It would be MUCH BETTER to make these libraries part of the GCC  
sources as part of gcclib perhaps, and have them subsumed into a  
coherent whole so that everyone does not have to deal with this.  GCC  
has way too many external dependencies.  These dependencies need to be  
removed!
</soapbox>

BTW, I discovered all of this because on FreeBSD-7.0 CURRENT I can  
build gcc-4.3.1 and these libraries just fine on a Core2 Duo Toshiba  
laptop of mine.  I inspected their builds and found that they were not  
64-bit builds.  That is what gave me the clue.

So the bug is that the ./configure of gmp works on FreeBSD but does  
not on Mac OS X.

Re: problems compiling gcc under Max OS X

[Chris Jefferson]

You should not do an 'in-build' tree for gcc. Also, did you try
without those flags?

Try doing this:

make a directory "gccobj" in the same directory as you have the source

do:

cd gccobj
../gccsourcedirectory/configure
make

Where you obviously replace gccsourcedirectory with the directory you
put gcc in.

Does this work? (It does for me, on 10.5.3, latest iPhone SDK beta)

problems compiling gcc under Max OS X

[Nicholas Miller]

I'm attempting to compile gcc 4.3.1 under Mac OS X (i686 processor)  
using gcc 4.0.1 which apple provided as part of their XCode tools.

./configure CC=gcc CFLAGS="-02 -m64 -mtune=k8"

and then of course a make all. I am getting the following:

gcc   -g -fkeep-inline-functions -DIN_GCC   -W -Wall -Wwrite-strings - 
Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition - 
Wmissing-format-attribute -fno-common   -DHAVE_CONFIG_H - 
DGENERATOR_FILE  -o build/genmodes \
     build/genmodes.o build/errors.o ../../build-i386-apple- 
darwin8.11.1/libiberty/libiberty.a
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: truncated or malformed  
archive: ../../build-i386-apple-darwin8.11.1/libiberty/libiberty.a  
(ranlib structures in table of contents extends past the end of the  
table of contents, can't load from it)
collect2: ld returned 1 exit status
make[3]: *** [build/genmodes] Error 1
make[2]: *** [all-stage1-gcc] Error 2
make[1]: *** [stage1-bubble] Error 2
make: *** [all] Error 2

I'm unfamiliar with this error. Can anyone point me in the right  
direction?
