main initializes what it is explicitly linked against. lib1 initializes lib2 before it initializes itself. -- See attached test_init_order.cpp: $ # -- create lib2 $ g++ -shared -o lib2.a -D LIBNAME=LIB2 test_init_order.cpp $ # -- create lib1 depends on lib2 $ g++ -shared -L. -l2 -o lib1.a -D LIBNAME=LIB1 -DCALLEE=LIB2 test_init_order.cpp $ # -- hide lib2 from main $ mv lib2.a /tmp/lib2.hide $ # -- link main against lib1 $ g++ -L. -l1 -o m -D LIBNAME=main -DCALLEE=LIB1 test_init_order.cpp $ # -- unhide lib2 $ mv /tmp/lib2.hide lib2.a $ ./m LIB2_init LIB1_init main_init main() LIB1() LIB2() main_fini LIB1_fini LIB2_fini $ # -- replace lib1 with a library that doesn't depend on lib2 $ # -- leave main alone $ g++ -shared -o lib1.a -D LIBNAME=LIB1 test_init_order.cpp $ /usr/local/bin/sudo slibclean $ ./m LIB1_init main_init main() LIB1() main_fini LIB1_fini -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33704
