[Turbulent]

Hi,

Is it possbile to install OpenFOAM 2.3.1 on RHEL Server 6.3?
The latest upgradable GCC version for the system is 4.4.7 while OpenFOAM demands GCC 4.5.0 and above.

Any help would be appreciated.

Thanks,

Jack

Hi,

Yes, it is possible. You even have two possibilities:

1. Build newer version gcc (using makeGcc script from ThirdParty folder, http://openfoamwiki.net/index.php/In...HEL#CentOS_6.5)

2. Install newer version of Gcc using Sofware Collections (https://access.redhat.com/documentat...e_Collections/).

Hi Jack,

here comes another way I used [but before try Alexey's suggestion that is a more elegant solution]

Similarly to you, I had a redhat server 6.4 Santiago, and gcc 4.4.7 without the possibility to become root.

Therefore I did the following:
1) take an hard disk with some GB of space and install on it virtual box portable http://www.vbox.me/
2) create a virtual machine installing CentOS 6.6
3) follow the instruction from http://www.openfoam.org/download/git.php
4) copy the compiled version of the virtual machine into your redhat 6.4 server
5) modify the environment variables
I test some tutorials and they are running well.

If you are interested in more details I copy below my diary of command executed:

In the virtual machine centOS6.6:

as root:

yum install git

download the sources

 cd /home/donQi/OpenFOAM

as normal user [not Root]

git clone git://github.com/OpenFOAM/OpenFOAM-2.3.x.git
    cd OpenFOAM-2.3.x
    git pull

save in /home/donQi/OpenFOAM the ThirdParty-2.3.1.tgz
(always as normal user)

tar xzf ThirdParty-2.3.1.tgz
    mv ThirdParty-2.3.1 ThirdParty-2.3.x

now as root:

yum groupinstall 'Development Tools'
    yum install openmpi openmpi-devel
    yum-config-manager --nogpgcheck --add-repo http://dl.atrpms.net/el6-x86_64/atrpms/stable
    yum install --nogpgcheck qtwebkit qtwebkit-devel
    yum install --nogpgcheck CGAL CGAL-devel

then :

 ln -s /usr/lib64/libboost_thread-mt.so /usr/lib64/libboost_thread.so

then as normal user

 gedit ~/.bashrc

add the lines:

 export PATH=/usr/lib64/openmpi/bin/:$PATH
    export LD_LIBRARY_PATH=/usr/lib64/openmpi/lib/:$LD_LIBRARY_PATH

then in terminal

source ~/.bashrc
    mpirun --version

you should see the message:
mpirun (Open MPI) 1.8.1
then as root:

 yum-config-manager --nogpgcheck --add-repo http://springdale.princeton.edu/data/puias/6.5/x86_64/os
    yum-config-manager --nogpgcheck --add-repo http://springdale.princeton.edu/data/puias/DevToolset/6.5/x86_64
    yum install --nogpgcheck devtoolset-1.1-runtime devtoolset-1.1-gcc.x86_64 devtoolset-1.1-gcc-c++.x86_64

This creates an isolated installation of GCC which can be used by sourcing the relevant script by typing the following in a local terminal:

   source /opt/rh/devtoolset-1.1/enable

then as normal user

    source /opt/rh/devtoolset-1.1/enable
    gcc --version

and we get

 gcc (GCC) 4.7.2 20121015 (Red Hat 4.7.2-5)

Finally!!!
ENVIRONMENT VARIABLES
in thunder VirtualMachine where we had /home/donQi/OpenFOAM/ we have just add in ~/.bashrc :

source $HOME/OpenFOAM/OpenFOAM-2.3.x/etc/bashrc

type:
foam
and you should be in the directory OpenFOAM-2.3.x
let's check

 foamSystemCheck

we get:

System check: PASS

Jeremy Clarkson get the vietnamese driving license!!! OK!!!!
Then

cd $WM_PROJECT_DIR

to avoid an error [ "/usr/bin/ld: cannot find -lz" ] before launching the Allrun install also

    yum install zlib-static
    yum install glibc-static

NOTE: if you get an error "NOKEY.." then use:

    yum install --nogpgcheck zlib-static
    yum install --nogpgcheck glibc-static

Then launch:

./Allwmake > make.log 2>&1

OK zero errors.

Now back to copy in our server.
>> Copying the compiled openFOAM to Redhat6.4 /
In the thunder VirtualMachine, copy all the files inside the OpenFOAM directory into the share directory:

sudo su - 
    cd -rL /home/donQi/OpenFOAM/* /media/sf_ShareThunder

NOTE: we add the L option to avoid the error "ERROR Cannot create symlink to"
Then back to the RedHat6.4 machine:
we copy the directory from the virtual machine (OpenFOAM-2.3.x, donQi-2.3.x and ThirdParty-2.3.x) into

/net/lnx6/home/donQi/OpenFOAM/thunderCompiled

In ~/.bashrc set :

 alias OF23x='. /net/lnx6/home/donQi/OpenFOAM/thunderCompiled/OpenFOAM-2.3.x/etc/bashrc'

e nella ect/bash

 foamInstall=/net/lnx6/home/donQi/OpenFOAM/thunderCompiled/

new terminal

  source ~/.bashrc
  OF23x
  tut
  cd incompressible/icoFoam
  blockMesh

OK works
