Due to some limitation of profiling software, it may be useful to link statically some libs into our programs. The following command links statically only lcrypto – while using dynamic linking on all other libs.
# gcc test.c -o test -Wl,-Bstatic -lcrypto -Wl,-Bdynamic
If you forget the endingÂ -Wl,-Bdynamic you’ll get the following error:
/usr/bin/ld: cannot find -lgcc_s collect2: ld returned 1 exit status
This because gcc tries to link statically libgcc too – but using the wrong file: libgcc_s.a. To link statically libgcc you have to add the -static-libgcc flag
# gcc test.c -o test -Wl,-Bstatic -lcrypto -static-libgcc
