Additional features
-------------------
The XFLAGS and XLIBS macros/environment variables control which additional
features (i.e. non-default compile-time features) should be enabled and
included during compilation.
The following table lists the available additional features--the column
*Requires* indicates, which libraries need to be installed for a feature; the
columns *XFLAGS* and *XLIBS* show, what needs to be added to these environment
variables to enable the corresponding feature:
Feature | Requires | XFLAGS | XLIBS
----------------------------------+----------+----------------+--------
GIF support: Load all frames and | giflib | -DGIF_SUPPORT | -lgif
play animations of GIF files | | |
----------------------------------+----------+----------------+--------
EXIF support: auto-orientate JPEG | libexif | -DEXIF_SUPPORT | -lexif
files according to their EXIF tag | | |
For instance, to enable GIF support, the giflib library needs to be installed
on your system and you need to execute the following shell commands before
running make:
$ export XFLAGS=-DGIF_SUPPORT
$ export XLIBS=-lgif
