Hi!

I'm having an error trying to compile GCC 4.4.2 on RHEL4 64Bit. The configure runs fine but when i try to make it says:

checking for suffix of object files... configure: error: in `/home/tra/gcc/gcc442_svn/obj/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.

My configure string looks like this:

obj]# ../source/configure --with-gmp=/home/tra/experimental/gmp-4.2.4 --with-mpfr=/home/tra/experimental/mpfr-2.3.2 --prefix=/home/tra/gcc/gcc442_svn/bin --enable-languages=c,c++

I've searched the error a lot and i'm not the only one with the error, some of the solution was to export LD_LIBRARY_PATH i tryed that without luck, my LD_LIBRARY_PATH is now:

echo $LD_LIBRARY_PATH
/usr/local/lib

I have also tryed moving the gmp and mpfr libs into the source of my gcc.

Any ideas? Thanks in advance!

More details about the error:

Yeah - looks like this line in config.log is quite specific about the error.

How did you build libmpfr? Are you sure you did a `make install'? Remember that in `--with-mpfr=<path-to-mpfr>', the `<path-to-mpfr>' should be the same as the argument to `--prefix' when you ran configure for mpfr.

If that doesn't give you something to do to work towards a solution, try posting the output of running `locate libmpfr.so.1' (after running `updatedb', of course ).

The installation of libmpfr and gmp has been used before for compiling an older GCC.

It looks like cc1 needs to see libmpfr at run-time, so add /home/tra/experimental/mpfr-2.3.2/lib to your LD_LIBRARY_PATH when you run configure, make etc. You'll probably also need to add /home/tra/experimental/gmp-4.2.4/lib as well.

John G

The people who create / maintain gcc, recommend the LFS method
to build gcc :
http://www.linuxfromscratch.org/lfs/view/6.5/

gcc, pass 1 :
http://www.linuxfromscratch.org/lfs/...gcc-pass1.html

gcc pass 2 :
http://www.linuxfromscratch.org/lfs/...ter06/gcc.html

If you do it this way, you will get a gcc, that is usable.
... And I guess, that's the whole idea about building a compiler ?

A gcc-4.x will probably be a good idea for the build of 4.4.x :
Install gcc4 with yum or up2date and get gcc4-4.1.2-44.EL4.x86_64.rpm
The c++ compiler : gcc4-c++ ( -4.1.2-44.EL4.x86_64.rpm ) seems to be
installed too, together with gcc4.
.. And may be you don't have to build one, 4.1.2 is versatile.
.....

Building 4..4.x : Suggest gcc-4.4.1 , probably easier.
Version 4.4.2 will be in Fedora 13, due June - 2010.
.....
..... ... Good luck !
