Split up the options into additional flags for the linker and additional libraries. Quoting from issue #636: > Here's an example, attempting to link one object file named example.o into an executable named example. Libcrypto here is superfluous and should be removed by --as-needed: ``` LDFLAGS="-Wl,--as-needed" LIBS="-lcrypto" gcc ${LDFLAGS} ${LIBS} example.o -o example # doesn't link libcrypto! gcc example.o ${LDFLAGS} ${LIBS} -o example # doesn't honor --as-needed! gcc ${LDFLAGS} example.o ${LIBS} -o example # works great! ``` > In short, the placement of your -l<foo> flags differs from that of all the other linker flags. Since ECL is only providing one big variable ld-flags for all of the linker flags, there's no correct way to pass in options like --as-needed and -l<foo> at the same time. Fixes #636.
