[Bug bootstrap/44714] New: libgcc configure: error: cannot compute suffix of object files

[Bug bootstrap/44714] New: libgcc configure: error: cannot compute suffix of object files

[jbare7 at gmail dot com]

I am trying to install the new version of gcc and am getting an error in the
process.

Version of gcc: 4.5.0
System type: Ubuntu 10.04

I downloaded the package gcc-4.5.0.tar.gz from
ftp://ftp.fu-berlin.de/unix/languages/gcc/releases/gcc-4.5.0/ and extracted the
file to my Desktop directory and I tried 

./configure
sudo make

Then I found out I needed GMP, MPFR, and MPC installed. I downloaded the
packages to my desktop and built and installed them, several times since some
of the latest versions did not seem to be compatible with each other. So after
a few tries I found a combination of versions of these that would install
correctly and still met the stated requirements for installing gcc 4.5.0

Then, finally I tried building gcc again with

./configure
sudo make

but then I get the error described in the summary above. Here is the last part
of the make process:

There's no need to build as root.

You don't need to install them, you can just put them in the gcc-4.5.0
directory, that's sometimes easier.

Or you can probably install them from your distro's package management system.

Like it says, see config.log for more details

also, please check whether this is the same issue as Bug 43819 (did you search
for existing bugs with "cannot compute suffix" before entering a bug?)

It's likely you need to set LD_LIBRARY_PATH so that libgmp etc can be found

That wouldn't be necessary if you installed your distro's packages, or if you
put the gmp/mpfr/mpc sources in the gcc-4.5.0 directory instead of building and
installing them manually

If I don"t build as root I get errors with removing certain files due to lack
of permissions for some reason.

I tried putting them in the gcc-4.5.0 directory and I tried installing them
from my distro, but neither of these worked to fix the error.

Sorry, but I am relatively new to Linux and am not experienced in reading this
file. However, in looking through it I noticed several places where it printed
an error and then a portion of C code where the error occurred. One of these
seemed to be checking the version of MPFR. Others couldn"t find certain .h
files.

Ah I did not find that bug report before. But as I said before, I'm fairly new
to Linux and I'm not sure how to set LD_LIBRARY_PATH correctly. I tried setenv,
but TAB completion did not recognize LD_LIBRARY_PATH as an option for this. And
yea, putting the other package directories in the gcc-4.5.0 directory didn't
fix the issue.

That's because you've tried to build as root already.
Remove the whole build tree (as root) then as non-root create a new directory
and make.

You don't have to do this, but there's no reason to build as root.  You do need
to "make install" as root if you are trying to install to e.g. /usr/local

You need to rename them to just "gmp" instead of "gmp-4.3.2" etc.

Or if you install from your distro you need the development packages, for gmp I
think that's libgmp3-dev, libmpfr-dev and libmpc-dev

Most of the errors are not fatal, they are testing the features of your system,
so it's normal to see errors. Near the end of the file will be one that causes
the problem, search for the text "cannot compute suffix". If you can't find it,
attach libgcc/config.log to this bug report.

Of course not, it's not an option. You could give absolutely any name to
setenv, so how can it predict what you want to type?

setenv is only the right command if you're using C shell, for sane shells you
would use:
  export LD_LIBRARY_PATH=/path/to/your/libs
For csh, if you insist on using it:
  setenv LD_LIBRARY_PATH /path/to/your/libs

But I really suggest you figure out how to install the libraries from Ubuntu's
packages, it will save you a lot of effort.  You could also try the gcc-help
mailing list, since I'm fairly sure this is user error, not a bug in gcc.

^ that should say "for Ubuntu" not "for gmp"

I tried this, but now I get an error when running make for gcc that it can't
find gmp-impl.h and longlong.h, even though these exist in the gmp directory
which I made.

I really want to use the package manager to install this, but gcc-4.5.0 does
not seem to be available as an upgrade for my version of gcc in the package
manager I have.

Then you're doing something wrong.

No, but libgmp3-dev, libmpfr-dev and libmpc-dev are available, and if you had
installed them then you would have been able to build gcc a lot more easily. 
It might be too late, if you've installed them yourself and didn't know what
you were doing you might have various broken installations on your system.  Or
they might be fine and you just need to use LD_LIBRARY_PATH.

I suggest you delete the whole gcc-4.5.0 directory, as you might have made a
mess of it. Then either install the gmp, mpfr and mpc dev Ubuntu packages OR
set LD_LIBRARY_PATH to find your existing installations (if you sure they're
installed OK). Then unzip the gcc sources again, but this time follow the
advice at http://gcc.gnu.org/install/configure.html and do not run configure
and make in the gcc-4.5.0 directory:

tar xzvf gcc-4.5.0.tar.gz
mkdir build
cd build
../gcc-4.5.0/configure

Now if it goes wrong you can just remove the 'build' directory and leave the
gcc-4.5.0 source directory untouched.

I'm going to close this bug, since it does seem to be user error not a gcc bug.

Either use LD_LIBRARY_PATH or re-install the gmp/mpfr/mpc libs from your
package manager.

If you still have problems, seek help on an Ubuntu forum or the gcc-help
mailing list.
