I got an unexpected link behaviour linking statically.

linking dynamically:

g++ -Wall -g0 -O3 -o batch_mesh_1 batch_mesh_1.o
- -L/raid/tecosim/it/devel/install-test/hp/lib -ltecosim -lteclic

everything works fine and ldd batch_mesh_1 gives:
         =>
        /usr/lib/libc.2 =>      /usr/lib/libc.2
        /usr/lib/libdld.2 =>    /usr/lib/libdld.2
        /usr/lib/libc.2 =>      /usr/lib/libc.2
        /usr/lib/libm.2 =>      /usr/lib/libm.2


linking statically:

g++ -Wall -g0 -O3 -static -o batch_mesh_1 batch_mesh_1.o
- -L/raid/tecosim/it/devel/install-test/hp/lib -ltecosim -lteclic

Here I have to add -lpthread manually, then the link succeeds:
g++ -Wall -g0 -O3 -static -o batch_mesh_1 batch_mesh_1.o
- -L/raid/tecosim/it/devel/install-test/hp/lib -ltecosim -lteclic -lpthread

and ldd batch_mesh_1 gives:
         =>
        /usr/lib/libdld.2 =>    /usr/lib/libdld.2
        /usr/lib/libc.2 =>      /usr/lib/libc.2
        /usr/lib/libdld.2 =>    /usr/lib/libdld.2
