Hello,

I am trying to buid OpenFOAM 1.3 from source on a stock Gentoo Linux box (gcc 4.1.1, glibc 2.4, X11R7). I just follow blindly and stupdly the installation procedure provided with the source code and I get the following errors (a few time before it stops to build):

SOURCE_DIR=.

Any idea? Help...

> cannot find -lOpenFOAM

seems something has gone wrong earlier when building the OpenFOAM library. Good luck.

Hi there,
I have waited a while before posting this but now I am really blocked. I have just recompile OF-1.3 on linux suse 10, gcc-4.0.2. All the libraries compiled fine, libOpenFOAM included. When I want to compile the libPVFoamReader, it first compiles the libvtkFoam then I get the previous "cannot find -lOpenFOAM". I am trying to link with paraview-2.5 compiled with cmake-2.4.2. Any suggestion?

All is explained on the wiki page. Thanks for having documented it!

[arkangel]

exactly in which part ?

Hi, I tried to compile a dev version of OpenFOAM (from svn), on a RHEL 5, using the compiler provided with the latest stable version of OpenFOAM. However, I get this linking error :

g++ -m32 -Dlinux -DDP -Wall -Wno-strict-aliasing -Wextra -Wno-unused-parameter -Wold-style-cast -O3 -DNoRepository -ftemplate-depth-40 -IlnInclude -I. -I/home/flurec/temp/dev/OpenFOAM-1.4.1-dev/src/OpenFOAM/lnInclude -fPIC -pthread Make/linuxGccDPOpt/kivaToFoam.o -L/home/flurec/temp/dev/OpenFOAM-1.4.1-dev/lib/linuxGccDPOpt \

Is there something that need to be fixed in a path ?

[johndeas]

May I add that, if I am in the src directory, and type wmake libso OpenFOAM, it reports an up to date libOpenFOAM.so

[arkangel]

go to ../OpenFOAM-1.4.1/src

and issue this command

%wmake libso OpenFOAM

It will tell you more information why OpenFoam cannot be built

[arkangel]

this file exist

/home/flurec/temp/dev/OpenFOAM-1.4.1-dev/lib/linuxGccDPOpt/libOpenFOAM.so

?

[johndeas]

Yes, it exists. I am checking all the paths in the various bashrc to understand why it is not taking into account.

I am also updatding my gcc to the one distributed with at http://powerlab.fsb.hr/ped/kturbo/OpenFOAM/release/ and thus I would like to clean all the executable. Is it possible to run something like wclean globally, or do I have to automate something to launch wclean in every directory where wmake is called ?

[johndeas]

wcleanAll ...

[johndeas]

After changing the gcc version, I wanted to clean/rebuild my installation with :

foam
wcleanAll
src
rm -rf */platforms
foam
Allwmake

However some librairies are not build. If I try wmake libso triSurface, I get

readSTLASCII.C:234:23: error: FlexLexer.h: no such file or directory

and various errors like

readSTLASCII.C:5079: error: â does not name a type

[johndeas]

I installed flex and zlib (to get zlib.h) from repositories even if I understood that they were built in the Allwmake process. If I type which flex, I get /usr/bin/flex, whereas I think I should have got something inside OpenFOAM path, had everything been setup properly. There were no warnings for the one-two hour compilation time before I left for weekend.

However, to my horror when I came back today, I saw I still have compilation errors. I found in the last compilation directives before it stopped compiling warnings like this one:

"readKivaGrid.H:232: warning: deprecated conversion from string constant to â"

and, readKivaGrid.H contains:

char* kivaPatchNames[nBCs] =
{
"piston",
"valve",
"liner",
"cylinderHead",
"axis",
"wedge",
"inflow",
"outflow",
"presin",
"presout",
"symmetryPlane",
"cyclic"
};

whith }; being at line 232

however, there were no errors, but warnings. The error message was:

make[3]: Leaving directory `/home/flurec/temp/OpenFOAM/OpenFOAM-1.4.1-dev/applications/utilities/mesh/conve rsion/kivaToFoam'
make[2]: Leaving directory `/home/flurec/temp/OpenFOAM/OpenFOAM-1.4.1-dev/applications/utilities/mesh/conve rsion'
make[1]: Target `application' not remade because of errors.

Also, if I type wmake libso kivaToFoam, I get
"libNULL.so is up to date"

My hypothesis is that the flex version from my repository is not uptodate (package 2.5.4a-41.fc6), but still, I do not understand why the one supplied with openFOAM in not the one used (and why I had to install zlib-devel to get zlib.h which is supplied in OF by the way). The latter has been built, I can found a flex executable in : applications/utilities/miscellaneous/foamFlex

I am really motivated to get OF built from development version, however I am limited in my understanding of what is currently going on.

[johndeas]

update: I should not have written wmake libso reaKiva, if I go the kivaToFoam directory and type wmake, I get :
FOAM_APPBIN/kivaToFoam is up to date.

also, if I type which foamFlex++, I get one which is inside FOAM_APPBIN

[jas]

It is written in the Install-Instruction that
you have to install the OPENFOAM direct into the HOME.

So if I´m right
/home/flurec/temp/dev/OpenFOAM-1.4.1-dev/lib/linuxGccDPOpt/libOpenFOAM.so
should look like
/home/OpenFOAM-1.4.1-dev/lib/linuxGccDPOpt/libOpenFOAM.so

[johndeas]

I modified two variables to take into account that I did not install in the home:

export WM_PROJECT_INST_DIR=/home/flurec/temp/$WM_PROJECT
export WM_PROJECT_USER_DIR=/home/flurec/temp/$LOGNAME-$WM_PROJECT_VERSION

Using similar settings, the stable binary version of OpenFOAM worked (and I was able to compile my owm solvers). But maybe I should ajust other variables to compile the core of OpenFOAM librairies ?
