在wscript
方法之后,我在dummy
中运行了一些自定义任务(apply_link
),
完成此dummy
任务之后,我想收集所有输出文件(将其设为*.dll
,*.exe
,*.o
,*.a
或*.elf
),然后在这些输出文件上运行另一个任务,但出现两个错误:
bld.path.get_bld().ant_glob(...)
找到的输出文件不会传递给任务。 wscript
看起来像这样:
#!/usr/bin/env python
# -*- encoding: utf-8 -*-
top = '.'
out = 'build'
VERSION = '0.0.0'
APPNAME = 'app'
from waflib import Task, TaskGen
def options(opt):
opt.load('compiler_c')
def configure(conf):
conf.load('compiler_c')
def build(bld):
bld.program(target='app', features='dummy', source='main.c')
bld.path.get_bld().ant_glob('**/*.elf **/*.a **/*.o', quiet=True)
bld(bld.path.get_bld().ant_glob('**/*.elf **/*.a **/*.o', quiet=True))
class tsk_1(Task.Task):
run_str = 'echo Hello from dummy and ${SRC} > ${TGT}'
color = 'GREEN'
@TaskGen.feature('dummy')
@TaskGen.after_method('apply_link')
def add_dummy_task(self):
# create one more *.o file
self.dummy_task = self.create_task(
'tsk_1',

@TaskGen.extension('.elf')

def process(self, node):
self.sk = self.create_task('size', node)
class size(Task.Task):
color = 'PINK'
def run(self):
print('Another hello from ${self.inputs[0]}')
Shell输出:

如果我重新运行build
命令waf
至少找到输出文件(当然,现在它们已经存在了;)),但是即使这样,它也不能运行我的其他自定义任务:
$ python waf build
Waf: Entering directory `/cygdrive/c/Users/user/Documents/waf-tests/test1/build'
[/cygdrive/c/Users/user/Documents/waf-tests/test1/build/apphello.o, /cygdrive/c/Users/user/Documents/waf-tests/test1/build/main.c.1.o]
Waf: Leaving directory `/cygdrive/c/Users/user/Documents/waf-tests/test1/build'
'build' finished successfully (0.040s)
所以我的问题总结为:
waf
不遵守@TaskGen.after('add_dummy_task')
完成后搜索输出文件的约束答案 0 :(得分:2)
由Taskgen.after
添加的约束仅在任务生成器方法的顺序上。它并不意味着对任务有任何约束。您可以使用--zone task_gen
选项看到这一点。
您描述的唯一来源是main.c
,它不会触发您的process
方法。
可能是拼写错误,但是您的第二个任务生成器没有source
所需的Taskgen.extension
属性,也没有features
属性。试试:
bld(
source = bld.path.get_bld().ant_glob('**/*.elf **/*.a **/*.o'),
features = 'dummy',
quiet = True
)
