OOF2: The Manual

oof2setuputils.check_exec
	7.5. `oof2setuputils` Reference

Name

oof2setuputils.check_exec — Check that an external program exists

Synopsis

from oof2setuputils import check_exec
check_exec(xfile)

Description

check_exec checks that the given file exists and is executable. The file must be in the user's PATH. check_exec can be used in the set_clib_flags function in a DIR.py file to ensure that the functions called by other utility functions exist.

Parameters

xfile: The name of the executable file to check.

Example

The examples used in the reference pages for add_third_party_includes and add_third_party_libs can be combined and written more robustly like this:

import oof2setuputils
def set_clib_flags(clib):
   if oof2setuputils.check_exec('Magick++-config'):
      oof2setuputils.add_third_party_includes('Magick++-config --cppflags', clib)
      oof2setuputils.add_third_party_libs('Magick++-config --ldflags --libs', clib)
   else:
      print "Can't find Magick++-config!"
