Check the contents of the file "qt-everywhere-opensource-src-4.6.4/mkspecs/common/g++.conf". The references to "gcc" and "g++" should indicate "gcc44" and "g++44" or whichever name your custom build of GCC is using, such as "gcc-4.5" and "g++-4.5".

Hi Bruno,

I am installing OpenFOAM-2.3.0 on centOS 6.5. I followed the instructions on http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL.

I think I got the same error in the last command of step #16. I've attached my mkqt.log here. I tried to type the two commands of:

 sed -i -e 's/= gcc/= gcc48/' qt-everywhere-opensource-src-4.8.4/mkspecs/common/g++.conf

 sed -i -e 's/= g++/= g++48/' qt-everywhere-opensource-src-4.8.4/mkspecs/common/g++.conf

and reperform step #16. It doesn't work and still gives me the same error.

However, one of my friends successfully install qt without any changes.

What should I do?

Thank you!

Hello,

I have a problem with installing OpenFOAM 2.3.0 on CentOS 6.5. I followed the procedures on this webpage http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

Everything is good until the last command of #16, i.e.

./makeQt qt-4.8.4 > mkqt.log 2>&1

I checked mkqt.log, and at the end of the file, it says:

Basic XLib functionality test failed!
 You might need to modify the include and library search paths by editing
 QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/daily/OpenFOAM/ThirdParty-2.3.0/qt-everywhere-opensource-src-4.8.4/mkspecs/linux-g++-64.
Error building: Qt-4.8.4

I've attached my mkqt.log file here.

Thanks!

Greetings Qi,

I've moved your other post from the other thread http://www.cfd-online.com/Forums/ope...-2-48-a-2.html - and merged with your first post on this thread, since both posts provide some crucial information.

This hack:

sed -i -e 's/= gcc/= gcc48/' ...

is not needed for these instructions, because the custom GCC meant to be used is the one built from source code when you follow the installation instructions.

The problem is likely related to missing or skipping some specific step. If you run the following commands, what do you get?

which gcc
which g++

In addition, did you do anything different from the instructions?

Best regards,
Bruno

Hi Bruno,

I might solved this by myself. So I just skipped your question and give my solution directly.

In a new terminal, I typed:

sudo -s
yum install qt-devel

After this, I redid step #16 and everything works fine.

I compared the installation process of openfoam 2.2.0 on centos from http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

It seems in step #2, qt-devel needs to be installed. However, they remove this for openfoam 2.3.0
http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

Hopefully it will help others.

Regards!
Qi

Hi Qi,

The reason why installing "qt-devel" is not in the instructions for OpenFOAM 2.3.0 is because for building ParaView 4.1.0 we have to use a custom Qt 4.8.4 version, as the system's version is not compatible.

Nonetheless, you raise an interesting point. When writing the installation instructions, OpenFOAM 2.2 had probably already been installed in the testing system, hence the needed X11 packages were already installed.

I'll have another try with a clean installation, to ascertain which specific packages are missing. Because installing the whole Qt development package and respective dependencies is something like 400MB of files, just because only a few MB were missing .

edit: So far, the missing package was "libXext-devel". Will make a new post when I've finished building ParaView4.

Best regards,
Bruno

[entropies]

Thanks for your explaination. I probably will go through clean installations later on for some other machines. So keep me posted!

Thanks!

[wyldckat]

OK, I've finally managed to build Qt 4.8.4 and ParaView 4.1.0, without installing the "qt-devel" package. I've updated the instructions accordingly: http://openfoamwiki.net/index.php/In...HEL#CentOS_6.5

Essentially, the missing packages are pretty much all of these:

libXext-devel libGLU-devel libXt-devel libXrender-devel libXinerama-devel libpng-devel libXrandr-devel libXi-devel libXft-devel libjpeg-turbo-devel libXcursor-devel

In other words, it's basically all of the ones that "qt-devel" depends on.

Best regards,
Bruno

Hi Bruno,

Thanks very much for your update!
Can I ask what is this qt or qt-devel? What're its functions? Seems like it has something to do with visualization or X11.

Qi

[wyldckat]

Hi Qi,

The "qt" package provides Qt 4.6.2. The "qt-devel" package provides the respective development files, so that we can build applications that link to the system's Qt 4.6.2. This would work just fine, if we were to build ParaView 3.12.0.

But for building ParaView 4.1.0, we have to use a more recent Qt version, which is why the installation instructions indicate that a custom build of Qt has to be made.

Best regards,
Bruno

Hi

For those who try to compile Qt with -python -mpi -mesa support might face the following error:

ERROR: Package gstreamer-app-0.10 not found

This can be solved by

yum install gstreamer-plugins-base-devel

Dear all,
I would like to share my experience in getting around this problem.
I got the following error while executing the step 10 on http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

./makeGcc gcc-4.8.1 gmp-5.1.2 mpfr-3.1.2 mpc-1.0.1 > mkgcc.log 2>&1

Note: above is using a log file to write the compiling procedure. I downloaded gmp-5.1.2 from mirror.anl.gov/pub/gnu/gmp/gmp-5.1.2.tar.bz2 and then extracted in the Third Party folder.
Then I ran again this step, everything went well.

with regards.

[wyldckat]

Greetings to all!

@Fabian: Thanks for sharing. I'll see if I can find the time in the future to update the instructions to include the options to build ParaView with Python and MPI support.

@Ashwani: Thank you for sharing your experience. If I understood you correctly, the script "getGcc" was unable to get the file "gmp-5.1.2.tar.bz2" from the ftp.gnu.org server. I'll make a note to update the script to rely instead on the GNU mirror server, which assigns automatically the closest server to the user.

Best regards,
Bruno

[AshwaniAssam]

@Bruno:The problem was what you have explained.

Thanks!
I've tested and updated a few minutes ago the git repository that has the getGcc script - https://github.com/wyldckat/scripts4OpenFOAM3rdParty/ - so that it now downloads by using the generic mirror address for all GNU source code .

[AshwaniAssam]

Thanks for your continued support to OpenFoam community.

Hi wyldckat,

Awesome job you did for the installation guide at http://openfoamwiki.net/index.php/In...CentOS_SL_RHEL

I however run into problems at step 17, the makeParaView4 script won't run properly, see attached log file. I run SL6. I hope you can help me.

[alexeym]

Hi,

I guess this can be relevant to the case: http://www.paraview.org/Wiki/ParaVie...aView_Settings

Note for MPI settings: If your MPI variables aren't set automatically (usually the case if the compiler wrapper [mpicxx] is not in the path or in some standard directory), toggle advanced options and set MPI_COMPILER variable to the full path of your mpi compiler (usually mpicxx), and configure. This should set all the required MPI variables. If not, then you might need to enter them manually.
If you get an error such as "mpi.h: no such file or directory" then set the CMAKE_C_FLAGS= -lmpi and the CMAKE_CXX_FLAGS= -lmpi++ . This is in addition to the MPI variables.

[Arjan82]

Actually, all I had to do is set this variable:

export MPI_INCLUDE=/usr/include/openmpi-x86_64

I came across two other things that I just mention which might help others:

I also needed to install python-devel, maybe add that to step 2?

When building OpenFOAM, foamyQuadMesh wouldn't build and I found out that some dep files point to $WM_THIRD_PARTY_DIR/platforms/linux64Gcc/ instead of $WM_THIRD_PARTY_DIR/platforms/linux64Gcc48

I solved it with a soft link but it may be better to change the dep files. You can find the files e.g. like this

cat `find . -name '*.dep'` | grep linux64Gcc\/

[wyldckat]

Greetings to all!

@Arjan: I've moved your questions from the other thread http://www.cfd-online.com/Forums/ope...hel-5-a-2.html, because that thread was meant for CentOS/RHEL/SL 5, and you're asking about SL 6.

And from your description and the build log, I believe you've mixed up the instructions that are meant for CentOS 5.10 with those for CentOS 6.5: http://openfoamwiki.net/index.php/In...HEL#CentOS_6.5 - as you can see, the instructions for 6.5 have "python-devel" in the list of packages to be installed.

As for the need to explicitly run:

export MPI_INCLUDE=/usr/include/openmpi-x86_64

Which exact SL (Scientific Linux) version are you using? I ask this because on CentOS 6.5, this variable is defined automatically.

Best regards,
Bruno

[Arjan82]

Ok, I might have messed up the two versions a bit indeed... That may also explain the wrong file references in the dep files...

I run Scientific Linux release 6.5 (Carbon), Linux version 2.6.32-431.29.2.el6.x86_64 (mockbuild@sl6.fnal.gov) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Tue Sep 9 13:45:55 CDT 2014

[wyldckat]

Quick answer: If you run the following commands:

gcc --version
g++ --version

and one or both state that you're using GCC 4.4.7, then I suggest that you remove the current installation you made of OpenFOAM 2.3.0 and start over again from the instructions meant specifically for CentOS 6.5, since it's very similar to RHEL and SL 6.5.
