I want to build a shared library using waf as it looks much easier and less cluttered than GNU autotools.

I actually have several questions so far related to the wscript I've started to write:

VERSION='0.0.1'
APPNAME='libmylib'

srcdir = '.'
blddir = 'build'

def set_options(opt):
 opt.tool_options('compiler_cc')
 pass

def configure(conf):
 conf.check_tool('compiler_cc')
 conf.env.append_value('CCFLAGS', '-std=gnu99 -Wall -pedantic -ggdb')

def build(bld):
 bld.new_task_gen(
  features = 'cc cshlib',
  source = '*.c',
  target='libmylib')

The line containing source = '*.c' does not work. Must I specify each and every .c file instead of using a wildcard?

How can I enable a debug build for example (currently the wscript is using the debug builds CFLAGS, but I want to make this optional for the end user).

It is planned for the library sources to be within a sub directory, and programs that use the lib each in their own sub directories.
