Help installing gcc 4.4.2

[Hung-Hsun Su]

Hi,

I was wondering if someone could help me install GCC 4.4.2 on one of our
system. I did
"./configure --prefix=/share/apps/gcc-4.4.2
--with-gmp=/share/apps/gmp-4.3.1 --with-mpfr=/share/apps/mpfr-2.4.1"
"make"

and got the following error message that I couldn't figure out what is
wrong.

Checking multilib configuration for libgcc...

Hey Hung-Hsun,

you shouldn't call configure from the gcc source directory!

Please follow the instructions at this link:
http://gcc.gnu.org/install/configure.html

What do you see in x86_64-unknown-linux-gnu/libgcc/config.log ?

Hey Hung-Hsun,

the configure script often tries to compile small test programs (embedded
into the configure script) to verify the compiler support of certain
options/features. By looking at the config.log you should be able to find
out what the test program is (line number in configure script) and how it
is compiled. Then you could possibly re-run the compiler command and check
what the real error message is ...

It is tellling me that it cannot find libmpfr.so when compiling
conftest.c  Are these tests critical for the installation?

Hung-Hsun

[su@alpha gcc]$ ls /share/apps/mpfr-2.4.1/lib

You need to ensure that it can.  If you have built MPFR yourself, I
strongly recommend that you discard what you built and rebuild it
using --disable-shared.  Otherwise, you need to ensure that the
dynamic linker can find libmpfr.so one way or another; one simple way
would be to set the LD_LIBRARY_PATH environment variable to point to
the right library.  Or you may simply need to run ldconfig.

Yes.

Thanks, adding the mpfr and gmp to LD_LIBRARY_PATH solved the problem.

I do wonder what kind of effect the flag --with-mpfr has on the
installation process. I thought this was used to specify where mpfr was
installed.

It is.  We expect that if you build mpfr yourself, you will configure
it --disable-shared, so that it is statically linked into gcc.  We
expect that if MPFR is installed in the system--i.e., you didn't
compile it yourself--then the system will take care of ensuring that
the dynamic linker can find it, e.g., via ldconfig.

Embedding the location of the mpfr shared library into the binary is
not a good idea by default, since it will mean that gcc will break if
you copy it to a different system.  That said, I think it would be
reasonable to add yet another configure option to do that, for people
who know they won't be copying it anywhere.

It would also be entirely reasonable to use -Bstatic when linking
against mpfr and gmp, on systems which have a linker which supports
-Bstatic.

That would be a very useful feature if one could hard-code the locations of the
mpfr and gmp with a configure option.
