Symbol lookup error??!

Dan1788 · July 9, 2014, 18:59

Hello,

I typed Allwmake in "src/thermophysicalModels" folder to compile a change I had made in the chemistryModel.C file located in "src/thermophysicalModels/chemistryModel" folder.

The compilation did not give me any errors. But when I compile my reactingFoam solver, it gives me the following error message:

symbol lookup error: /home/Dan/apps/OpenFOAM/OpenFOAM-2.2.0/platforms/linux64GccDPOpt/lib/libreactionThermophysicalModels.so: undefined symbol: _ZN11yyFlexLexer6yywrapEv

Can anyone help me to understand what this means and how I can get rid of this error? Thanks!

Hello Daniel,
though this is an old post but were you able to solve it?

Sorry to bother. Have you solved this problem and could you give me some suggestions？I compiled src/thermoPhysicalModels/chemistryModel successfully.But when i run tutorials/combustion/laminar/counterFlowFlame2D using reactingFoam, it reminded me that

Code:

reactingFoam: symbol lookup error: /home/dyfluid/OpenFOAM/OpenFOAM-7/platforms/linux64GccDPInt32Opt/lib/libchemistryModel.so: undefined symbol: _ZN4Foam18TDACChemistryModelINS_17psiReactionThermoENS_19sutherlandTransportINS_7species6thermoINS_11janafThermoINS_15PengRobinsonGasINS_6specieEEEEENS_16sensibleEnthalpyEEEEEE8typeNameE
