Hi,
I want to compile my code in C++ (because this is what I know and I am doing an experiment), but the standard makefile '.include <bsd.kmod.mk>' works only with the C compiler. At this stage, I do not have any idea about the various bits of code that must be linked and that is why I cannot simply write my own makefile.
This is the test code that I am wanting to compile:
This is the Makefile - which currently does not work:
The file <bsd.kmod.mk> does not seem to contain anything that prevents compilation in C++, but it includes <bsd.sys.mk> which seems to be where the problems come from. The first thing I would like to do is to simply use g++ and to remove all the references to c etc.
Can you help me to write a working makefile so I can use KLD via a C++ coded module?
What libraries would I need to link?
