g++ works in my machine but not work on another machine

[northfly]

I use the following command and am able to generate the execution file

g++ -o T201_UniformFilm -std=c++11 -I ~/Work/PhD/Runs/Eigen324 -O3 T201_UniformFilm.cpp BoundaryCondition.cpp CalculateEvaporation.cpp CalculateFlowfield.cpp CalculationDomain.cpp FiniteVolume.cpp Geometry.cpp Meshing.cpp Physics.cpp PoreThroat.cpp Testing.cpp

but after I copy all stuff to the supercomputer, they also got the same compiler installed, I cannot get the results, always says "...is not defined", looks like it cannot find the head file. But all the .cpp file and .h file are there, all the library are copied keeping the same file structure.

What can be the problem, Thanks!

The error message: I didn't copy all of them, it is too long, but something like thi.

[doug4]

what is not defined? Can you get the actual error message?

[northfly]

thanks doug4, I edited my topic, please take a look!

Those undefined staff are all the variables, member variables, member functions

[MikeyBoy]

Those are link errors. Are all those undefined references to symbols defined in your code? Or are they in external libraries?
