What should be the -L options for the gcc linker if the sysroot option is used?

Question

GCC

I need to cross compile a C++ project.
For gcc, the --sysroot=/home/me/mysysroot/ parameter is passed.
But there are also -L parameters that tell the linker the path to individual libraries.
So the question is -L should the path be the full path in my host machine where cross compilation is performed or the path relative to the path specified in the sysroot parameter?

Answer 1

-L must the path be the full path on my host machine where the cross compilation is being done, or a path relative to the path specified in the sysroot parameter?

The path can be a full path on the host machine, or if it starts with a character =or a string $SYSROOT($SYSROOT must not be interpreted by the shell and must be in the compiler arguments as such), it is interpreted relative to sysroot.
