g++ error unrecognized command line option

I'm trying make Makefile.

I get error:

g++: error: unrecognized command line option ‘-Wl’
g++: error: unrecognized command line option ‘--out-implib’

Can someone please explain what's the problem and how can I fix it?

Thanks.

Please show the entire command line, or nobody is going to be able to help you.

The GCC compiler driver can be called as either "gcc" or "g++" (and on many systems "cc" or "c++"). The -Wl command-line option tells the compiler driver to pass the following comma-separated options to the linker.

You'll want to verify that g++ is in fact the GNU compiler on your system, and not something that pretends to be the GNU compiler.

Note that --out-implib as a linker flag is only applicable on systems that use the PE binary format (that is, Microsoft Windows, ReactOS, older versions of BeOS, and a largely-forgotten operating system called SkyOS). If you're building software for any other platform, the linker will reject that option.

Anyway, need to see the whole command-line. If you're using "make" to build the software in question, paste the command line immediately proceededing the error message. If you're using a "-j" option to make, remove it so as to ensure that you're finding the correct failing invocation.
