从SConscript文件调用CheckLib

我正在尝试从SConscript文件中检查是否存在库,如下所示:

# Not sure if this bit is relevant:
Import('env')
env = env.Clone()

# This is what I'm trying to do:
conf = env.Configure()
if conf.CheckLib('gcrypt'):
    pass # actually something more interesting

......但它不起作用。我得到的是来自scons的不透明错误,如下所示:

scons: ***
File "/home/src/foo/bar/SConscript", line 49, in <module>

...第49行是conf = env.Configure()行。

这是在Mac OS X上,我不希望找到提到的库。如何在SConscript文件中检测到这一点?

答案 0 :(得分:0)

我对此进行了测试,效果很好。也许它是你如何创建或传递env的问题。这是我的示例代码,以防它有用:

<强> SConstruct

env = Environment()
env.SConscript('SConscript', exports='env', duplicate=0)

<强> SConscript

Import('env')

env = env.Clone()

conf = env.Configure()
if conf.CheckLib('gcrypt'):
  pass

结果如下:

$ scons
scons: Reading SConscript files ...
Checking for C library gcrypt... no
scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.
