- - install gcc (https://www.cfd-online.com/Forums/openfoam-installation/74257-install-gcc.html)

i try to install gcc-4.3.3 it asked me to specifythe path of gmp.h and mpfr.h
how can i do this in one command.
thanks.

Greetings ahmed,

My guess is that happened to you, after managing to get makeGcc to work properly :)

OK, by my estimate, the problem you're having now is due to 3 missing files in mpfr that comes with the Third Party General package. See this post #13, where I've already made available a patch for creating the missing 3 files. Instructions on how to apply it are on that same post :)

After that, try again the makeGcc command.

Best regards,
Bruno

PS: you could have continued to use your previous thread ;)

this is not the problem

first thank you for your interest
i have already downloaded the whole compressed file and extract it it works good until the installation of mpfr-4.2.1. but when i try to install gcc-4.3.3 it ask me to specify the place pf gmo.h and mpfr.h so i type:
$ /home/ahmed/OpenFOAM/ThirdPArty-1.6/gcc-4.3.3/configure --with-gmp-include=/home/ahmed --with-mpfr-include=/home/ahmed/OpenFOAM/ThirdParty-1.6/mpfr-4.2.1

it say correct version of mpg ------ yes
correct version of mpfr-------no
i tried /usr/local directory
i tried /home/ahmed directory
i tried --with-mpfr
i tried --with mpfr-build

Greetings Ahmed,

OK, you can make your life easier if you run:

Code:

. $HOME/OpenFOAM/OpenFOAM-1.6/etc/bashrc

cd $WM_THIRD_PARTY_DIR

./makeGcc gcc-4.3.3 2>&1 | tee make.log

These three lines will: setup the OpenFOAM environment; go to the ThirdParty folder; and build gcc-4.3.3, while showing the output on screen, as well as putting what you see on screen into the file make.log.

Now, IF you still want to do everything by hand, then to simplify your efforts, type the following two lines:

Code:

ln -s $WM_THIRD_PARTY_DIR/gmp-4.2.4 $WM_THIRD_PARTY_DIR/gcc-4.3.3/gmp

ln -s $WM_THIRD_PARTY_DIR/mpfr-2.4.1 $WM_THIRD_PARTY_DIR/gcc-4.3.3/mpfr

Then compile gcc using:

Code:

cd $WM_THIRD_PARTY_DIR/gcc-4.3.3

mkdir build

cd build

../configure --enable-languages=c,c++ --with-pkgversion='OpenFOAM' --enable-__cxa_atexit --enable-libstdcxx-allocator=new --with-system-zlib --prefix=$WM_THIRD_PARTY_DIR/gcc-4.3.3/platforms/$WM_ARCH

For those variables that start with a '$' you'll need to setup OpenFOAM's environment, by running that first line at the top, the one with bashrc.

is the gcc was installed

thank you very much when i followed your advice it wrote that
gmp is already built
mpfr is already built
gcc is already built

Greetings Ahmed,

If it wrote that in only a few seconds, that's because you've unpacked the binary packages of the ThirdParty (namely ThirdParty-1.6.linux*Gcc.gtgz).

To force the rebuilding of gmp+mpfr+gcc, you'll have to remove the contents inside the "platforms" folders that exist inside each folder. You can do that by running:

Code:

rm -rfi $WM_THIRD_PARTY_DIR/gmp-4.2.4/platforms/$WM_ARCH$WM_COMPILER_ARCH

rm -rfi $WM_THIRD_PARTY_DIR/mpfr-2.4.1/platforms/$WM_ARCH$WM_COMPILER_ARCH

rm -rfi $WM_THIRD_PARTY_DIR/gcc-4.3.3/platforms/$WM_ARCH$WM_COMPILER_ARCH

Then try again to build gcc et al. It should take about 20 to 60 minutes to complete the whole task, depending on the machine you have.

Best regards,
Bruno
