Do you have pkgconfig installed? In setupext.py, it looks like the
'z' lib is added only if we are not finding pkgconfig:
def add_ft2font_flags(module):
'Add the module flags to ft2font extension'
if not get_pkgconfig(module, 'freetype2'):
module.libraries.extend(['freetype', 'z'])
If get_pkgconfig is returning True, but it is not configured properly
to find libz for freetype2, you may fall into a configure black hole
where libz never gets added.
Does it help to modify this function to read:
def add_ft2font_flags(module):
'Add the module flags to ft2font extension'
if not get_pkgconfig(module, 'freetype2'):
module.libraries.extend(['freetype', 'z'])
add_base_flags(module)
basedirs = module.include_dirs[:] # copy the list to avoid inf loop!
for d in basedirs:
module.include_dirs.append(os.path.join(d, 'freetype2'))
p = os.path.join(d, 'lib/freetype2/include')
if os.path.exists(p): module.include_dirs.append(p)
p = os.path.join(d, 'lib/freetype2/include/freetype2')
if os.path.exists(p): module.include_dirs.append(p)
basedirs = module.library_dirs[:] # copy the list to avoid inf loop!
for d in basedirs:
p = os.path.join(d, 'freetype2/lib')
if os.path.exists(p): module.library_dirs.append(p)
else:
add_base_flags(module)
module.libraries.append('z')
