Please remove ":" before <link>shared. The ":" separates parameters - and you want both <include>include and <link>shared to
be part of 'requirements' parameter.

So, you're not using gcc, you're using g++, but it should not matter, since "-x c" changes the input language to C. You
also have -fPIC there already. To add -w you can use

        <cflags>-w

in the requirements parameter to the "lib" function.

The errors you get do not appear related to complication options at all - but rather by something else in your sources.
Did you try looking at the source to determine what's up? Warnings like 'implicit declaration of malloc' are also
risky, and unrelated to build tool - probably somethign needs fixing in the source code.
