A tool to generate NativeCall code from C headers
You will need gccxml and gcc/g++ 4.9
Beware some distributions provide gccxml as castxml and it's bad (does not want to take c99 headers), you will need to change the code to use gccxml.real
or make sure the gccxml executable is gccxml
You will need gccxml and gcc/g++ 4.9 or castxml (it's based on clang/llvm)
By default GPTrixie use GCCXML.
Beware some distributions provide gccxml as castxml and it's bad, you will need to change the code to use gccxml.real
or make sure the gccxml executable is gccxml if you want to use gccxml.
To use castxml you will need to use the --castxml option and give it the standard option castxml need to use (it's the --std option of castxml, c99 or c11 should work fine on recent version)
