[petsc-users] Compiling lists all the libraries

[Y. Shidi]

Dear developers,

I stated to use certain libraries in the Makefile of my code,
but it turns out that Petsc automatically uses all the libraries.
Some are listed twice.
I am wondering how does this happen.

-Wl,-rpath,/home/ys453/Sources/petsc/arch-linux2-c-debug/lib 
-L/home/ys453/Sources/petsc/arch-linux2-c-debug/lib 
-Wl,-rpath,/home/ys453/Sources/petsc/arch-linux2-c-debug/lib

-lgcc_s -lquadmath -lpthread -lrt -lm -lpthread -lz -lstdc++ -ldl 
-lparmetis -lmetis -lpetsc -lboost_timer -lboost_system

Thank you for your time.

Kind Regards,
