This sounds a bit overly complex to me. It sounds to me like the main requirement here is to enable doing a compile step on a command-line specified directory or file. Possibly even a list of files/directories. Note that this is just about doing the C++ compiling. Linking and other steps does not provide as much error information so seems less important. Having the build system figure out which files use a particular function sounds like it would be slow enough that it's better to simply type out the files/directories you know are affected. And once you get those passing you can do a more general full-tree build. Or is the ask here really for something more complex? / Jonas _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
