Hi there,
I would like to improve a bit the packaging of pyaudio, and for that,
I need to do the following when configuring my package:
- to be able to retrieve a header file (sndfile.h). I need the full
pathname, because I need to read its content
- to be able to retrieve a library file. I need the full pathname,
including the library prefix and suffix/extension,
because I need to load it with ctypes.
I've shamelessly copied and pasted code from
numpy.distutils.system_info, and I manage to retrieve informations for
my library, and to retrieve the full pathname for sndfile.h, but I don't
know how to get the full shared library file. For now, my sndfile_info
looks like that:
class sndfile_info(system_info):
#variables to override
section = 'sndfile'
notfounderror = SndfileNotFoundError
libname = 'sndfile'
header = 'sndfile.h'
def __init__(self):
system_info.__init__(self)
def calc_info(self):
""" Compute the informations of the library """
# Look for the shared library
sndfile_libs = self.get_libs('sndfile_libs', self.libname)
lib_dirs = self.get_lib_dirs()
for i in lib_dirs:
tmp = self.check_libs(i, sndfile_libs)
if tmp is not None:
info = tmp
break
else:
return
# Look for the header file
include_dirs = self.get_include_dirs()
inc_dir = None
for d in include_dirs:
p = self.combine_paths(d,self.header)
if p:
inc_dir = os.path.dirname(p[0])
headername = os.path.abspath(p[0])
break
if inc_dir is not None:
dict_append(info, include_dirs=[inc_dir],
headername = headername)
self.set_info(**info)
return
Any help to get the full library name would be appreciated (I cannot
use find_library from ctypes.util, because I have no guarantee that it
will return the same one than distutils),
Thanks,
David
