- What is the 'soname' option for building shared libraries for?
- How does linker find shared library without SONAME
(in this case libm is considered before the object files and discarded independently from the content of the two.)
$ gcc -Wl,--as-needed -lm someunit1.o someunit2.o -o program
(this is the correct linking order to get libm linked only if needed.)
$ gcc -Wl,--as-needed someunit1.o someunit2.o -lm -o program
