yea i dont know how to get cmake to compile my C files using clang instead of clang++
if file extension is "c" - it will compile it as "c" file.
if extension is "cpp" - it will compile it as "c++" file.

but not if they are mixed in the same library?
AT
you can mix c and cpp files
MG
eg if the lib has both C and C++ files
MG
and C++ declares a C definition
MG
eg
extern void main(int argc, char ** argv);MG
would that still need to be
extern "C" void main(int argc, char ** argv); since even tho it is being compiled IN the same library as the C++ file, it will not link the same way unless the file defining main is ALSO a C++ fileAT
extern "C"
void main(int argc, char ** argv);AT
in both header and cpp file you need to use to use extern "C"
MG
eg $ g++ main.cpp realMain.c
MG
vs $ g++ main.cpp realMain.cpp
AT
what build system you use ?
MG
cmake
AT
eg $ g++ main.cpp realMain.c - this is not good.
MG
and MacOS which cmake uses clang
AT
it must be separate commands for c++ and c
I
G++ will compile everything mangled. Gcc wont iirc
MG
even if the files are in the same command (g++ a.cpp b.c) ? eg is it not smart enough to automatically extern "C" any referenced C functions belonging to C files, in C++ files?
I
There is no smart auto extern
