[R-pkg-devel] Link compiled C object to internal package file

Yeah, but that would require completely rewriting the C code to accept a variable for something that is used hundreds of times as a simple macro. (Most of that C code is an old library bundled with the package, so not my work in that regard.) It would still be enormously easier to robustly provide a relative location within the compiled source object to direct it to the file ... but how?
I assume you have something like #define MYMACRO "path/to/file" and this MYMACRO is used here and there in the internal library. Instead, you can set #define MYMACRO getPath() and this getPath function is defined somewhere and uses R's C API to find that file and return the path (does someone know whether the functionality of system.file() is directly accessible from C?). I?aki
