I've been building an automated build framework for my UpLib system,
which requires PIL. I've made a couple of changes to the PIL setup.py
which might go into the standard release, and attach a patch.
Basically two changes:
1. It's useful to be able to set TIFF_ROOT, JPEG_ROOT, etc. without
editing the setup.py file. This patch modifies the default values for
those setup variables to be read from the environment, as PIL_TIFF_ROOT,
PIL_JPEG_ROOT, etc. This allows a build script to just set the
environment variables to pass them in to setup.py.
2. When linking _imagingft on msys, the auxiliary libraries (-ljpeg,
-lz, etc.) need to be passed as arguments to the link command. So I've
modified the link code
if feature.freetype:
defs = []
if feature.freetype_version == 20:
defs.append(("USE_FREETYPE_2_0", None))
exts.append(Extension(
"_imagingft", ["_imagingft.c"], libraries=["freetype"],
define_macros=defs
))
to read instead
if feature.freetype:
defs = []
if feature.freetype_version == 20:
defs.append(("USE_FREETYPE_2_0", None))
exts.append(Extension(
"_imagingft", ["_imagingft.c"], libraries=["freetype"] + libs,
define_macros=defs
))
adding back in the necessary libraries. Similarly for _imagingtiff and
_imagingcms.
Should this perhaps be done only for msys, via an "extra" parameter,
such as that used with _imagingcms? Be happy to change it, but it seems
to work fine on OS X and Ubuntu, too, as is.
