How would one go about creating a kernel module which utilizes C++ code?
I was planning on using the macro __cplusplus to toggle using
extern "C" { }, however the bsd.kmod.mk style Makefiles seem to
force the language to -std=c99 even when compiling with c++ .my initial steps have been as follows: take a functioning C based kernel module and rename to .cc added extern "C" around the includes. #defined key words such as new to xxx_new recompiled the new .cc file by hand without -std=c99, but keeping all the flags as the Makefile set them. then linked using the Makefile and finally loaded the module.
as long as I do not make any calls into kernel functions things seem to work (load), however when I make a call to mtx_init then on load i get the following error: __gxx_personality_v0 undefined.
thoughts/ideas/suggestions?
thanks
