The simplest way is to do something like this:

[[!format python """ #!python

use GTK

CCFLAGS = ' pkg-config --cflags gtk+-2.0 ' LINKFLAGS = ' pkg-config --libs gtk+-2.0 '

env = Environment(CCFLAGS=CCFLAGS, LINKFLAGS=LINKFLAGS) env.Program('toaster-test.c') """]] Remember to keep them separate, you cannot do what you do in makefiles and specify --cflags and --libs together.

However, the cleaner, more correct - and really not much harder - way is to use ParseConfig like so:

[[!format python """ #!python env = Environment()

add support for GTK

env.ParseConfig('pkg-config --cflags --libs gtk+-2.0')

env.Program('toaster-test.c') """]] Of course, the above steps assume pkg-config and GTK+ are installed (though they will almost always be). If you want your configuration to be able to check for the existence of pkg-config, use something like what follows:

[[!format python """ #!python env = Environment()

def CheckPKGConfig(context, version): context.Message( 'Checking for pkg-config... ' ) ret = context.TryAction('pkg-config --atleast-pkgconfig-version=%s' % version)[0] context.Result( ret ) return ret

def CheckPKG(context, name): context.Message( 'Checking for %s... ' % name ) ret = context.TryAction('pkg-config --exists '%s'' % name)[0] context.Result( ret ) return ret


conf = Configure(env, custom_tests = { 'CheckPKGConfig' : CheckPKGConfig, 'CheckPKG' : CheckPKG })

if not conf.CheckPKGConfig('0.15.0'): print 'pkg-config >= 0.15.0 not found.' Exit(1)

if not conf.CheckPKG('gtk+-2.0 >= 2.4.9'): print 'GTK+-2.0 >= 2.4.9 not found.' Exit(1)

Your extra checks here

env = conf.Finish()

Now, build:

env.ParseConfig('pkg-config --cflags --libs gtk+-2.0')

env.Program('toaster-test.c') """]]
