Multiple Definition errors

Palabos Bug Reports
#1

Dear all,

when trying to compile a case with more than one .cpp file, I got multiple definition errors of type


liggghtsCouplingWrapper.cpp:(.text+0x5c0): multiple definition of `plb::computeCopyReducedBulk(plb::Box3D)'
onetoone.o:onetoone.cpp:(.text+0xa00): first defined here

for the functions


plb::computeCopyReducedBulk(plb::Box3D)

in twoPhaseModel3D.h and


plb::stringToTwoPhaseModel(std::string) 
plb::computeCopyEdges(plb::Box3D, std::vector<plb::Box3D, std::allocator<plb::Box3D> >&)
plb::computeCopyCorners(plb::Box3D, std::vector<plb::Box3D, std::allocator<plb::Box3D> >&)

in multiGridGenerator3D.hh

Adding the

[code=“cpp”]
inline


keyword to the implementations of the four functions resovles the issue.

best regards
Philippe

Thanks a lot for reporting this issue, Philippe!

We added the inline keyword as you suggested, and will put this online with the next release.

Hello Jonas, dear all,

a new issue of this type has come up in version 1.5r1 in the file multiPhysics/twoPhaseModel3D.h:

[code=“cpp”]
TwoPhaseModel stringToTwoPhaseModel(std::string modelName)



needs to be declared inline to avoid any multiple definition errors. Please correct this in the next release.

thanks
Philippe

Hello Philippe,

I have tried with those changes you specified here. But still it shows multiple definition errors. Is it works fine for you ?

Hi Listy,

for me everything worked - but I can’t tell whether there are other issues like this hidden in other parts of the code. The conditional compilation via scons might hide this as I only use a small subset of the features of Palabos.
