Hi Foamers,

I am using OpenFoam-v2012 on WSL. When my cases have #calc or #codestream, dynamic code failed to compile giving the following error:

Any help please? Is this problem related to WSL or just I missed something?

Thank you

Hi,


To reproduce the error, I think we need a minimal reproducible example.

Hi HPE,

For example let see this blockMeshdict :

One issue is the missing dollar sign for the following variables:

hex (0 1 2 3 4 5 6 7) (xcells ycells zcells) simpleGrading (1 1 1)

Having said that I strongly recommend you to use #eval expression instead of #calc. With #eval, you will not need to deal with any compilation. Please search 'eval' among the tutorial cases and OpenFOAM release notes.

[Geb1313]

Hi HPE,
Nice! Half of my problem is solved. I used #eval instead of #calc. However still the problem with #codestream persisted to continue. I was running a dambreak using interfoam. I want to introduce initial conditions for alpha.water using #codestream like this:

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 0 0 0 0 0 0];

//internalField uniform 0;

internalField #codeStream
{
codeInclude
#{
#include "fvCFD.H"
#};

codeOptions
#{
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/meshTools/lnInclude
#};

//libs needed to visualize BC in paraview
codeLibs
#{
-lmeshTools \
-lfiniteVolume
#};

code
#{
const IOdictionary& d = static_cast<const IOdictionary&>(dict);
const fvMesh& mesh = refCast<const fvMesh>(d.db());
scalarField alpha(mesh.nCells(), 0.);

forAll(alpha, i)
{
const scalar x = mesh.C()[i][0];
const scalar y = mesh.C()[i][1];
const scalar z = mesh.C()[i][2];

if (y <= 0.2)
{
alpha[i] = 1.;
}
}

writeEntry(os, "", alpha);
#};
};

And the error message was similar which looks a compilation error like this:

Did you add all libraries to the 'libs' entry in system/controlDict?

You have Gcc63 as the compiler type, which makes it look like you have a separate gcc installation.
You should check the value of your LD_LIBRARY_PATH to verify that libmpfr (perhaps libgmp too) are accessible.

Since the compilation worked, but not the loading, use 'ldd -v' on the dynamically generated lib. Use Google or Stackoverflow or man if you aren't familiar with ldd.

[Geb1313]

Thank you for the reply olesen,
which gcc on the command line shows:

/opt/OpenFOAM/OpenFOAM-v2012/ThirdParty/platforms/linux64/gcc-6.3.0/bin/gcc

I don't think the problem is related to separate gcc installation(?)
To use the ldd -v [file], the file "_9a2905356e5313e2ff419c83e22111805dc3 aa4d.so" is not existing. When I look in to dynamicCode folder, there is no platforms sub-folder.

Looking in to config.sh/setting, I found:

_foamEtc -config compiler

archDir="$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER_ARCH"

case "$WM_COMPILER_TYPE-$WM_COMPILER" in

then

I am not sure whether this will help or not, but it is only this I could figure out about "mpfr" and "gmp".

Sorry my ignorance about linux system
