Hi everyone!


I am using OpenFOAM 2.3.0 and trying to compile a modified version of icoFoam (with temperature equation and thermophysical properties varying with temperature) and I'm getting the following error:

"
/usr/bin/ld: cannot find -lthermophysicalModels

collect2: ld returned 1 exit status

make: *** [/home/duarte/OpenFOAM/duarte-2.3.0/platforms/linuxGccDPOpt/bin/own_icoFoamPV] Error 1
"

Can anyone tell me how can I make the program find this library?

Thank you for your help!

(I'm afraid this post is in the wrong sub-forum as I haven't seen many threads about compilation errors around here. If so, please redirect me to the correct one)

Hi,

if you take a look at options files in Make folder of compressible solvers, usually it is:

...
EXE_LIBS = \
    -lfluidThermophysicalModels \
    -lspecie \
...

Hi Alexey,

Thank you for your quick reply!

My Make/options file is as follows:

"
EXE_INC = \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/sampling/lnInclude \
-I$(LIB_SRC)/thermophysicalModels/basic/rhoThermo \
-I$(LIB_SRC)/thermophysicalModels/basic/fluidThermo \
-I$(LIB_SRC)/thermophysicalModels/basic/basicThermo

EXE_LIBS = \
-lfiniteVolume \
-lsampling \
-lthermophysicalModels
"

I thought this was correct. I am using rhoThermo to calculate the fields rho () and mu (). I just need these fields from rhoThermo.

Please advise, thanks a lot!

Well,

$ cd $FOAM_LIBBIN 
$ pwd
.../OpenFOAM-2.3.0/platforms/.../lib
$ ls | grep Thermo
libSLGThermo.dylib
libfluidThermophysicalModels.dylib
libmultiphaseMixtureThermo.dylib
libreactionThermophysicalModels.dylib
libsolidThermo.dylib
libtwoPhaseMixtureThermo.dylib
$

So change your -lthermophysicalModels to something that is available like -lfluidThermophysicalModels.

Alexey,

You are right. There is a libfluidThermophysicalModels.so file in the opt/openfoam230/platforms/LinuxGccDPOpt/lib directory, and not a libthermophysicalModels.so file.

However, in opt/openfoam230/src, I cannot find a "fluidThermophysical" directory, but there is a thermophysicalModels directory

Supposedly, existing a thermophysicalModels directory in /src, a .so file would be expected to exist in opt/openfoam230/platforms/LinuxGccDPOpt/lib directory, right?

Ok, problem solved, I was getting it all wrong, my options file ended up as:

EXE_INC = \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/sampling/lnInclude \
-I$(LIB_SRC)/thermophysicalModels/specie/lnInclude \
-I$(LIB_SRC)/thermophysicalModels/basic/lnInclude


EXE_LIBS = \
-lfiniteVolume \
-lsampling \
-lfluidThermophysicalModels \
-lspecie


Thank you so much for your help Alexey!

Not exactly. It's right, for example, for surfMesh folder in src (so it's libsurfMesh.so), turbulenceModels folder (it's turbulenceModels.so), but thermophysicalModels are split into several dynamic libraries (thermophysicalModels/basic -> libfluidThermophysicalModels.so, thermophysicalModels/SLGThermo -> libSLGThermo.so, etc.). Another example of such split is postProcessing folder.
