[OpenFOAM.com] Trouble compiling Waves2Foam with OpenFoam-v2106

Legacy · December 20, 2022, 06:09

Hello Foamers.
I am trying to compile Waves2Foam but experiencing some reference linking issues. I tried modifying $WM_DIR/rules/*/c++ file but it did not help. Any ideas? Thanks. Here is the output:

Code:

Make/linux64GccDPInt32Opt/porousWaveFoam.o:(.data.rel.ro._ZTVN4Foam8OPstreamE[_ZTVN4Foam8OPstreamE]+0x80): undefined reference to `Foam::UOPstream::writeQuoted(std::string const&, bool)'
collect2: error: ld returned 1 exit status

looks like you might be using the gold linker, which is more stringent about the linking requirements.
The new OpenFOAM versions have this type of linking:

Code:

LINK_LIBS   = $(c++DBUG) 

LINKLIBSO   = $(CC) $(c++FLAGS) -shared \ 
    -fuse-ld=gold 

LINKEXE     = $(CC) $(c++FLAGS) \ 
    -fuse-ld=gold 

# Link dummy stub to resolve libPstream symbols used by libOpenFOAM 
ifneq (,$(findstring -lOpenFOAM,$(PROJECT_LIBS))) 
    LINKEXE += -L$(FOAM_LIBBIN)/dummy -lPstream 
endif
