Re: [Getfem-users] getFEM g++ error

[Yves Renard]

Dear Andy,

The libgetfem.a library should be complete ... of course you also have to link standard libraries (-lm) and optionnally  -lqhull -lblas -llapack and also optionnaly mumps. It the installation has been performed from the sources, the best in fact is to go to the tests directory of getfem

cd tests
rm laplacian.o
make laplacian

and compile with the same options (adapting the include directory and the location of the getfem library if the installation has been made).

Yves.

Hello,  I've been using the python interface upon discovery and installation of 5.0 but now I see I should use gmm for my transient analysis and requires c++.  Python worked fine, but upon attempting running the example laplacian.cc, with:

g++ -std=c++11 -o output laplacian.cc -I/usr/local/getfem/include -L/usr/local/getfem/lib/libgetfem.a

I get a stream of errors along the line of

laplacian.cc:(.text._ZN6getfem18ATN_smatrix_outputIN3gmm10row_matrixINS1_8rsvectorIdEEEEE5exec_Emt[_ZN6getfem18ATN_smatrix_outputIN3gmm10row_matrixINS1_8rsvectorIdEEEEE5exec_Emt]+0x356): undefined reference to `bgeot::operator<<(std::ostream&, bgeot::tensor_ranges const&)'
collect2: error: ld returned 1 exit status

Looking for assistance in this matter.

Thank you,

Andy
