debug vs release

[Thiago Farina]

To have different sets of compilations flags depending whether you are doing a local debug build versus doing a release build for public consumption, is the following (two separate build files in two different directories) the best approach?

$ cat out/Debug/build.ninja

cc = clang

cflags = -g

rule compile

  command = $cc $cflags -c $in -o $out

$ ninja -C out/Debug

$ cat out/Release/build.ninja

cc = clang

cflags = -g0 -O2

defines = -DNDEBUG

rule compile

  command = $cc $cflags $defines -c $in -o $out

$ ninja -C out/Release

That works. Or you can use a single directory and regenerate your
build.ninja when you change flags.
