我想用waf触发makefile来构建另一个库。为此,我创建了以下任务:
def build(bld):
def run(self):
bld_dir = self.generator.bld.path.get_bld()
src_dir = self.inputs[0].parent
tgt = self.outputs[0]
tgt_dir = bld_dir.make_node(os.path.splitext(tgt.name)[0])
cmd = 'BUILDDIR="{tgt_dir}" make config gdb=1 debug=1 cc={cc} && BUILDDIR=" {tgt_dir}" make'.format(
tgt_dir = tgt_dir.abspath(),
cc = self.env.get_flat("CC"))
self.exec_command(cmd, cwd=src_dir.abspath())
return self.exec_command(['cp', lib.abspath(), tgt.abspath()],
cwd=tgt_dir.abspath())
bld(
rule = run,
source = "Makefile",
target = 'metis',
)
我如何告诉waf该任务创建了一个静态库,以便我可以在use关键字中使用“metis”:
bld(
features = "cxx cxxprogramm"
source = "main.cpp",
target = 'main',
use = 'metis'
)
答案 0 :(得分:4)
为了最终解决问题,我创建了一个on link任务,基本上什么都不做(类似于ccroot.py中的假lib):
from waflib.TaskGen import feature, after_method
from waflib.Tools.ccroot import stlink_task
class custom_stlib(stlink_task):
""" Dummy link task """
pass
@feature("custom_stlib")
def custom_lib(self):
self.env['custom_stlib_PATTERN'] = 'lib%s.a'
self.link_task = self.create_task('custom_stlib', [])
self.link_task.add_target(self.target)
def build(bld):
# ...
bld(
features = "cxx custom_stlib",
target = 'metis',
after = "metis_bld",
)
