That is not a compiler option, so gcc-help is not the right mailing
list. It is a GNU linker option. The right list for questions about
the linker is binutils@xxxxxxxxxxxxxxx See
http://sourceware.org/binutils/
The -no-undefined option is documented in the linker manual. When
creating a shared library, the default for an undefined symbol is to
not report an error. The --no-undefined option changes this to report
an error.
This is useful if you want to ensure that the shared library is
complete in itself, and does not have any references to other shared
libraries.
