HELP_USAGE = """Usage: generate_libs.py root libs classes internal external.
|
|
root - Root directory where to create libs.
|
|
libs - Number of libraries (libraries only depend on those with smaller numbers)
|
|
classes - Number of classes per library
|
|
internal - Number of includes per file referring to that same library
|
|
external - Number of includes per file pointing to other libraries
|
|
|
|
For example:
|
|
./genbench.py /tmp/build 200 100 15 5
|
|
|
|
To try the waf part, do:
|
|
waf configure build -p -j5
|
|
|
|
To test the autotools part, do:
|
|
touch README AUTHORS NEWS ChangeLog &&
|
|
autoreconf --install --symlink --verbose &&
|
|
mkdir autotools-build-dir &&
|
|
cd autotools-build-dir &&
