Build Options
-------------
* Environment Variable: ``MAX_CONCURRENCY=n``. By default, Pillow will
use multiprocessing to build the extension in parallel. This may not
be ideal for machines that report a large number of cores compared
to the actual processor power. Set ``MAX_CONCURRENCY`` to 1 to disable
parallel building, or to a larger number to limit to that number of
parallel tasks.
* Build flags: ``--disable-zlib``, ``--disable-jpeg``,
``--disable-tiff``, ``--disable-freetype``, ``--disable-tcl``,
``--disable-tk``, ``--disable-lcms``, ``--disable-webp``,
``--disable-webpmux``, ``--disable-jpeg2000``. Disable building the
corresponding feature even if the development libraries are present
on the building machine.
* Build flags: ``--enable-zlib``, ``--enable-jpeg``,
``--enable-tiff``, ``--enable-freetype``, ``--enable-tcl``,
``--enable-tk``, ``--enable-lcms``, ``--enable-webp``,
``--enable-webpmux``, ``--enable-jpeg2000``. Require that the
corresponding feature is built. The build will raise an exception if
the libraries are not found. Webpmux (WebP metadata) relies on WebP
support. Tcl and Tk also must be used together.
Sample Usage::
$ MAX_CONCURRENCY=1 python setup.py build-ext --enable-[feature] install
