OpenFOAM install on RHEL 5.5
 
I’m attempting to install OpenFOAM on RHEL 5.5. I’ve downloaded gcc44 and all necessary dependencies. How do I configure the source to use gcc44 (/usr/bin/gcc44) instead of gcc (/usr/bin/gcc)? Is this a setting in OpenFOAM-1.7.1/etc/bashrc? Thanks in advance.

Greetings phinallydone,

I'm assuming you are using the x86_64 architecture version of RHEL. If so, scroll down in OpenFOAM's bashrc and search for this piece of code:
Code:

x86_64)
        case $WM_ARCH_OPTION in
        32)
            export WM_COMPILER_ARCH='-64'
            export WM_CC='gcc'
            export WM_CXX='g++'
            export WM_CFLAGS='-m32 -fPIC'
            export WM_CXXFLAGS='-m32 -fPIC'
            export WM_LDFLAGS='-m32'
            ;;
        64)
            WM_ARCH=linux64
            export WM_COMPILER_LIB_ARCH=64
            export WM_CC='gcc'
            export WM_CXX='g++'
            export WM_CFLAGS='-m64 -fPIC'
            export WM_CXXFLAGS='-m64 -fPIC'
            export WM_LDFLAGS='-m64'
            ;;
        *)
            echo "Unknown WM_ARCH_OPTION '$WM_ARCH_OPTION', should be 32 or 64"
            ;;
        esac
        ;;

There simply change the gcc and g++ entries to gcc44 and g++44.

If you aren't using the x86_64 architecture version of RHEL, then you can simply export WM_CC and WM_CXX accordingly to your architecture.

Best regards,
Bruno

Worked great. Thanks!

Hello Bruno,

I sincerely hope you can point me in the right direction.

Since my system gcc version is 4.1.2. I have installed a gcc version 4.4.5 in a /opt/gcc445 so the command "which gcc44" point to /opt/gcc445/bin/gcc44, and similarly for g++44.

I also changed the /etc/bashrc file accordingly to post #2 above.

The beginning of log file for Allwmake is:

Makefile:54: /home/hnguyen/OpenFOAM/OpenFOAM-1.7.1/wmake/rules/linux64gcc44/general: No such file or directory
Makefile:55: /home/hnguyen/OpenFOAM/OpenFOAM-1.7.1/wmake/rules/linux64gcc44/c++: No such file or directory
make: *** No rule to make target `/home/hnguyen/OpenFOAM/OpenFOAM-1.7.1/wmake/rules/linux64gcc44/c++'. Stop.

Thank you for your time and advice.

Could it be that you need to make wmake rules for your new linux64gcc44 setup? Does this help?:

Code:

cp -r /home/hnguyen/OpenFOAM/OpenFOAM-1.7.1/wmake/rules/linux64Gcc /home/hnguyen/OpenFOAM/OpenFOAM-1.7.1/wmake/rules/linux64gcc44

Hello Gijs,

Thank you for your suggestion. I think I did this thing all wrong. I should have placed the compiler in the ThirdParty directory for it to work correctly as recommended by this

http://www.openfoam.com/archive/1.6/docs/README.php.

I will try this and update this post.

UPDATE:
So I stumbled upon these blogs by Bruno:

http://www.cfd-online.com/Forums/blo...-7-series.html

http://www.cfd-online.com/Forums/blo...-openfoam.html

Following these blogs and everything works. OpenFOAM-1.7.1 and ParaView 3.8.0 were installed on my Scientific Linux 5.5 (a clone of Enterprise Red Hat 5.5) 64 bit system.

Regards,

Hello,
since I have a similar problem with installing OF I decided to post here. I hope it isn't a problem :)
The cluster I am using has gcc44 installed in usr/bin/gcc44 and so far I changed the entries in bashrc as required in post #2 to gcc44 and g++44, but I still got some errors.
When running Allwmake from the Thirdparty directory I got the message that my compiler is not able to produce working executables, and running the Allwmake in apllications gave the errfile I've attached. I tried to find if there's g++44 but couldn't find it.
Maybe it would be best to compile gcc locally?
Thanks in advance for the help, I really appreciate it.

Hi Yavor,

Are those really all the errors you got? The log starts with applications and a bit further down it says "/usr/bin/ld: cannot find -lfiniteVolume". Did $WM_PROJECT_DIR/src actually compile properly?

This is not the entire error log, because I stopped the compilation process when I saw these errors, but the /src couldn't compile properly also. I found that others have had the same error "cannot find -lfiniteVolume", but I decided to ask for some help not to mess up things :)

gwierink May 19, 2011 04:15

Aha, that's exactly the point. The error you got is quite late in the installation process, when you're compiling the applications. So, your src didn't compile properly. Do you have a build log of src?

Yes, I'm attaching it below.

Line 11 of your error log says
Quote:

OPwrite.C:29:17: error: mpi.h: No such file or directory
If you're compiling on a desktop, probably ThirdParty (openmpi) did not compile properly. If you're on a cluster (and using something else than the openmpi provided with ThirdParty) you need to specify where your MPI library lives. So, how did compilation of ThirdParty go?

I'm compiling on a cluster, and "which mpicxx" returns /opt/bin/mpich2/bin/mpicxx. I've attached the build logs from thirdparty.

gwierink May 22, 2011 06:43

Hmm, logfile line 17:
Quote:

configure: error: Could not run a simple C++ program. Aborting.
Have you set your compiler directives correctly, so that OpenFOAM can find gcc-4.4? Have a look here, it's a different cluster, but maybe it's useful ...

Hi,
now I want to install OpenFOAM 2.1.0 on RHEL5.5, and I have installed Gcc4.6.3, but OpenFOAM still can't make correct, how should I do?

I'm going to answer you with a quote from a recent thread:

It will not do anything to your system.

It comes with its own GCC version 4.6.x.

There are multiple guides/help on how to compile OF on CentOS 5.x releases.

This thread has guide for OF-1.7 but the procedure is the same for 2.1
