I believe that should be:
g++ -L/usr/lib
'-L' is for library paths, not include paths.
Additionally, you need to include both libraries in your linker
invocation. So it should be:
g++ *.o -o myprogr.exe -L/usr/lib -lssl -lcrypto
'ld' is a single pass linker, so the order of '-lss -lcrypto' matters.
See the ld(1) man page for details. http://linux.die.net/man/1/ld.
