Hey; I'm trying to write a new rockspec for Lua-SDL2[1], using the "builtin" backend so that users won't need CMake installed.
I'm having trouble cleanly configuring it to find the SDL2 headers. Context: LibSDL2 normally installs its headers to /usr/include/SDL2/; however, certain platforms install to other locations, which may not necessarily end in an SDL2/ folder. If I search for "SDL2/SDL_scancode.h" in external_dependencies and include "$(SDL2_INCDIR)/SDL2" in incdirs, then the rock builds just fine on my machine; however, unusual platforms would not be able to override with a usable SDL2_INCDIR, since it assumes the existence of SDL2/. If I search for just "SDL_scancode.h" and reference just "$(SDL2_INCDIR)", then any platform can be directed to the right location. But, luarocks doesn't know to search /usr/include/SDL2, so now *every* platform needs manual configuration to build the rock. Am I missing a way to give LuaRocks "hints" to augment its search path with subdirectories of the platform defaults? Any pointers would be appreciated; ~Joseph Wallace [1]: https://github.com/Tangent128/luasdl2/tree/luarocks-builtin ------------------------------------------------------------------------------ _______________________________________________ Luarocks-developers mailing list Luarocks-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/luarocks-developers
