Re: [Getfem-users] Compilation problem

[Yves Renard]

Dear Riccardo,

So, in my opinion, ... it should work. May be try to change the order of the library in the compilation.
Try for instance

g++ -O3 laplacian.cc -lgetfem -lm -lmuparser -lblas -lmetis -llapack -lgetfem

However, it seems to me that the order is correct ...

Do you use the same compiler for both the library and the program ?

Yves.

In fact the library seems to contain the code:

Dear Riccardo,

The function getfem::ATN::is_zero_size() is defined in the file
getfem_assembling_tensor.cc. So I don't see where is the problem here.
Normally, the library should contain the code for this function. Could
you test it with a
nm -a libgetfem.a | grep is_zero_size
for instance, or
readelf -Ws libgetfem.so | grep is_zero_size
?

Yves.
