c_tests¶
Various configuration tests.
-
waflib.Tools.c_tests.
link_lib_test_fun
(self)[source]¶ Task generator method
The configuration test
waflib.Configure.run_build()
declares a unique task generator, so we need to create other task generators from here to check if the linker is able to link libraries.Feature: link_lib_test
-
waflib.Tools.c_tests.
check_library
(self, mode=None, test_exec=True)[source]¶ Configuration Method bound to
waflib.Configure.ConfigurationContext
Checks if libraries can be linked with the current linker. Uses
waflib.Tools.c_tests.link_lib_test_fun()
.Parameters: mode (string) – c or cxx or d
-
waflib.Tools.c_tests.
check_inline
(self, **kw)[source]¶ Configuration Method bound to
waflib.Configure.ConfigurationContext
Checks for the right value for inline macro. Define INLINE_MACRO to 1 if the define is found. If the inline macro is not ‘inline’, add a define to the
config.h
(#define inline __inline__)Parameters: - define_name (string) – define INLINE_MACRO by default to 1 if the macro is defined
- features (list of string) – by default c or cxx depending on the compiler present
-
waflib.Tools.c_tests.
check_large_file
(self, **kw)[source]¶ Configuration Method bound to
waflib.Configure.ConfigurationContext
Checks for large file support and define the macro HAVE_LARGEFILE The test is skipped on win32 systems (DEST_BINFMT == pe).
Parameters: - define_name (string) – define to set, by default HAVE_LARGEFILE
- execute (bool) – execute the test (yes by default)
-
class
waflib.Tools.c_tests.
grep_for_endianness
(*k, **kw)[source]¶ Bases:
waflib.Task.Task
Task that reads a binary and tries to determine the endianness
-
color
= 'PINK'¶
-
hcode
= b"\tdef run(self):\n\t\ttxt = self.inputs[0].read(flags='rb').decode('latin-1')\n\t\tif txt.find('LiTTleEnDian') > -1:\n\t\t\tself.generator.tmp.append('little')\n\t\telif txt.find('BIGenDianSyS') > -1:\n\t\t\tself.generator.tmp.append('big')\n\t\telse:\n\t\t\treturn -1\n"¶

-
waflib.Tools.c_tests.
grep_for_endianness_fun
(self)[source]¶ Task generator method
Used by the endianness configuration test
Feature: grep_for_endianness
-
waflib.Tools.c_tests.
check_endianness
(self)[source]¶ Configuration Method bound to
waflib.Configure.ConfigurationContext
Executes a configuration test to determine the endianness
-
waflib.Tools.c_tests.
conf
(f)¶ Decorator: attach new configuration functions to
waflib.Build.BuildContext
andwaflib.Configure.ConfigurationContext
. The methods bound will accept a parameter named ‘mandatory’ to disable the configuration errors:def configure(conf): conf.find_program('abc', mandatory=False)
Parameters: f (function) – method to bind
-
waflib.Tools.c_tests.
feature
(*k)¶ Decorator that registers a task generator method that will be executed when the object attribute
feature
contains the corresponding key(s):from waflib.Task import feature @feature('myfeature') def myfunction(self): print('that is my feature!') def build(bld): bld(features='myfeature')
Parameters: k (list of string) – feature names
-
waflib.Tools.c_tests.
before_method
(*k)[source]¶ Decorator that registera task generator method which will be executed before the functions of given name(s):
from waflib.TaskGen import feature, before @feature('myfeature') @before_method('fun2') def fun1(self): print('feature 1!') @feature('myfeature') def fun2(self): print('feature 2!') def build(bld): bld(features='myfeature')
Parameters: k (list of string) – method names
-
waflib.Tools.c_tests.
after_method
(*k)[source]¶ Decorator that registers a task generator method which will be executed after the functions of given name(s):
from waflib.TaskGen import feature, after @feature('myfeature') @after_method('fun2') def fun1(self): print('feature 1!') @feature('myfeature') def fun2(self): print('feature 2!') def build(bld): bld(features='myfeature')
Parameters: k (list of string) – method names
