Hi all

Just finished compiling/uploading 1.7.0 for CentOS/RHEL/SL 5.x 64bit based OS'es.

As usual it can be found here

Thank you!

Hi Niels,

Any chance of making a 32 bit version?

Hi Bjorn

I don't use 32bit and I do not know how many CFD guys really use 32bit.

So I will have my focus on 64bit, but the manual instructions on the wiki page should apply to 32bit as well just strip the x86_64 from the yum packages.

To compile 1.7.0 you need to do the following.

as root

yum install gcc gcc-c++ bison ncurses-devel tix glibc-devel flex flex-devel zlib-devel libXt-devel

As user

cd $HOME

mkdir OpenFOAM

wget http://downloads.sourceforge.net/foam/ThirdParty-1.7.0.gtgz?use_mirror=mesh

wget http://downloads.sourceforge.net/foam/OpenFOAM-1.7.0.gtgz?use_mirror=mesh

cd OpenFOAM

tar -xvf ../ThirdParty-1.7.0.gtgz
tar -xvf ../OpenFOAM-1.7.0.gtgz

put this line in your .bashrc and source it

alias OF17=". $HOME/OpenFOAM/OpenFOAM-1.7.0/etc/bashrc"

. $HOME/.bashrc

Now the command OF17 should load the OpenFOAM environment

Then you need a couple of dependencies to compile gcc-4.4.4

mkdir $HOME/build
cd $HOME/build

GMP---

wget ftp://ftp.gmplib.org/pub/gmp-5.0.1/gmp-5.0.1.tar.bz2

tar -xvf gmp-5.0.1.tar.bz2

cd gmp-5.0.1

OF17

./configure --prefix=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1

make -j2 (for two cpu cores, 4 if you have 4 cores)
make install

MPFR---

cd $HOME/build

wget http://ftp.gnu.org/gnu/mpfr/mpfr-2.4.2.tar.gz

tar -xvf mpfr-2.4.2.tar.gz

cd mpfr-2.4.2

OF17

./configure --prefix=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/mpfr-2.4.2 --with-gmp=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1

make -j2
make install

GCC---

cd $HOME/build

wget http://ftp.gnu.org/gnu/gcc/gcc-4.4.4/gcc-4.4.4.tar.gz

tar -xvf gcc-4.4.4.tar.gz

cd gcc-4.4.4

mkdir build (important to compile gcc out of source)

cd build

OF17

../configure --prefix=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gcc-4.4.4 --with-gmp=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1 --with-mpfr=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/mpfr-2.4.2

make -j2
make install

Now you should be able to go into the ThirdParty-1.7.0 folder and issue

OF17
./Allwmake

and the same for OpenFOAM.

You will have to figure paraview out for yourself since I don't compile it in the ThirdParty folder.

Hope this will get you somewhere.

Hi, Niels

I got stuck after the command:
../configure --prefix=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gcc-4.4.4 --with-gmp=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1 --with-mpfr=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/mpfr-2.4.2

I got the error given in the attached screenshot. Any clue about what went wrong?

Hi again,

Sorry, the above error came after the "make j2" command line

Hi

It seems gcc cant find mpfr according to this

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35577

Did you remember to run OF17 before configuring else the path for gmp and mpfr cant be found

You could try with the full path instead of

--with-gmp=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1 --with-mpfr=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH/mpfr-2.4.2

use

--with-gmp=$HOME/OpenFOAM/ThirdParty-1.7.0/platforms/linux/gmp-5.0.1 --with-mpfr=$HOME/OpenFOAM/ThirdParty-1.7.0/platforms/linux/mpfr-2.4.2


Or add gmp and mpfr to your LD_LIBRARY_PATH

Hi,
I tried your suggestion but the same error occurred.

Hi Bjorn,

Hope you are well

I had the same problem when using gcc 4.1.2.
I switched to openfoam-1.7.0 and started to compile gcc-4.4.4 with
the system compiler and could not get it to work so before switching
environment from 1.6 to 1.7, compile gcc-4.4.4 with
the compiler from openfoam-1.6.x, which was gcc-4.3.3 for me.

Then no problemo.

Hi Niklas & Niels,

I am not that good in linux commands, so I probably need a detailed cookbook recipe to get OF1.7 to work. Niels did a good job in doing so, but I got stuck. Niklas you also probably give good advise, but I am not able to use it (becuase of my lack of knowledge in linux).

rgds
Bjorn

[niklas]

what does it say if you type

gcc -v

[bhh]

Niklas,

the Attached screenshot show the result after gcc -v. This is however after I changed to 1.6.x
Bjorn

[niklas]

right,
but Im guessing that you didnt use that version when compiling gcc-4.4.4.

However, if you stay in the 1.6.x environment you can compile gcc-4.4.4
with gcc-4.3.3 and that will probably work better

using
../configure --prefix=$HOME/OpenFOAM/ThirdParty-1.7.0/platforms/$WM_ARCH$WM_COMPILER_ARCH/gcc-4.4.4 --with-gmp=$HOME/OpenFOAM/ThirdParty-1.7.0/platforms/$WM_ARCH$WM_COMPILER_ARCH/gmp-5.0.1 --with-mpfr=$HOME/OpenFOAM/ThirdParty-1.7.0/platforms/$WM_ARCH$WM_COMPILER_ARCH/mpfr-2.4.2

make
make install

...assuming that the enviroment variables WM_ARCH and WM_COMPILER_ARCH are the same
in 1.7.0 and 1.6.x and that your installation is under $HOME/OpenFOAM

Hi,
When I executed the command you propose I get the response:
bash: ../configure: No such file or directory

Any clue what might be wrong?

Bjorn

[niklas]

go to the gcc-4.4.4 directory and create a dir called...for instance build with 'mkdir build'
'cd build' and execute the command from there
you should not run the configure script in the gcc-4.4.4 directory

[bhh]

Niklas,
I feel stupid: in ThirdParty-1.6.x there is no gcc-4.4.4 only gcc-4.3.3. As I indicated in an earlier post I am not well adapted to linux commands.
Bjorn

[niklas]

The gcc-4.4.4 should reside in the ThirdParty-1.7.0 directory.

Just 'cd ~/OpenFOAM/ThirdParty-1.7.0' while still in the 1.6.3 environment.

[bhh]

Niklas,
In OpenFOAM-1.7.0 there is no gcc folder, only:
Allwmake bin doc README ReleaseNotes-1.7 src tutorials
applications COPYING etc README.html ReleaseNotes-1.7.html test wmake
Bjorn

[bhh]

Niklas
I meant to say that in OpenFOAM ThirdParty-1.7.0 thre is no gcc flder, only:
[user@OpenFOAM ThirdParty-1.7.0]$ ls
Allclean makeParaView paraview-3.8.0 platforms wmakeFiles
Allwmake metis-5.0pre2 ParMetis-3.1 scotch_5.1
AllwmakeLibccmio openmpi-1.4.1 ParMGridGen-1.0 tools

Bjorn

[bhh]

NIklas,
I found the gcc-4.4.4 under /home/user/OpenFOAM/ThirdParty-1.7.0/platforms/linux/gcc-4.4.4

But there were no files present. This is what I got when executing the command
bash: ../configure: No such file or directory
