problem installing gcc
 
hello every one
i was trying to install open FOAM. after installation it asked me to install gcc third party due to environment problem. the gcc-4.3.3 asked me to install gpm and mpfr. when i wrote this command
$ /home/ahmed/OpenFOAM/ThirdParty-1.6/gmp-2.4.1/configure
then
$ make
it told me that maint.mk isn't exist. same thing when i wrote
$ make installation
again the same thing has happened when i did this with mpfr.:confused:
Thanks

It may be the case where your system is too old to accept an installation of the lastest gcc compiler. I experienced something similar on a cluster with CentOS 4.5.
What operating system do you have?

Did you try installing gmp-4.2.4 and mpfr-2.3.0?

This is strange. I don't see such a version in the release list for ubuntu. (https://wiki.ubuntu.com/Releases). If you made a typo and instead of 9.1 you meant 9.10, then this is the latest version and you should not worry about it. I would actually expect openfoam to work with the compiler included with the distribution.

Greetings ahmed,There is a script in the ThirdParty folder named makeGcc. It will compile gmp, mpfr and gcc for you. Just run with:
Code:
./makeGcc gcc-4.3.3
Additionally, you might need to apply a patch to fix 3 missing files from mpfr. The patch is available on this post. Additionally, that thread has some useful info on how to compile gcc in ThirdParty :)

Best regards,
Bruno

i tried this
/home/ahmed/OpenFOAM/ThirdParty-1.6/makeGcc gcc-4.3.3
it gave me
/home/ahmed/OpenFOAM/ThirdParty-1.6/gmp-4.2.4/maint.mk: No such file or directory
make: *** No rule to make target `/home/khattab/OpenFOAM/ThirdParty-1.6/gmp-4.2.4/maint.mk'. Stop.
Finished building gmp.

Greetings ahmed,

OK, there have been reports (here is one of them) in the past about missing files; these seem to occur due to some weird bugs when unpacking the ThirdParty-1.6.General.tgz file.
So, you should try unpacking it again and see if the missing file appears. If not, download the ThirdParty-1.6.General.tgz file again and check it with md5sum after the download is complete, and compare with the value available on the OpenFOAM download page.

Best regards,
Bruno
