Base for c programs/libraries

class waflib.Tools.c.link_task(*k, **kw)

Base class for all link tasks. A task generator is supposed to have at most one link task bound in the attribute link_task. See waflib.Tools.ccroot.apply_link().

color = 'YELLOW'

Color for the console display, see waflib.Logs.colors_lst

weight = 3

Try to process link tasks as early as possible

inst_to = None

Default installation path for the link task outputs, or None to disable

chmod = 493

Default installation mode for the link task outputs

add_target(target)

Process the target attribute to add the platform-specific prefix/suffix such as .so or .exe. The settings are retrieved from env.clsname_PATTERN

exec_command(*k, **kw)

Wrapper for waflib.Context.Context.exec_command(). This version set the current working directory (build.variant_dir), applies PATH settings (if self.env.PATH is provided), and can run long commands through a temporary @argfile.

Parameters

cmd (list of string (best) or string (process will use a shell)) – process command to execute

Returns

the return code

Return type

int

Optional parameters:

1. cwd: current working directory (Node or string)

2. stdout: set to None to prevent waf from capturing the process standard output

3. stderr: set to None to prevent waf from capturing the process standard error

4. timeout: timeout value (Python 3)

exec_mf()

Create manifest files for VS-like compilers (msvc, ifort, …)
