This commit makes the decimal module support optional: since Python 3.3 it relies on an external library. The source code of this library is available built-in as part of the Python sources, but in Buildroot we generally prefer to use the external library when possible. To achieve this, this commit adds a patch to Python that is similar to the one we use for expat support, but this time for the libmpdec/mpdecimal library. As a consequence, since mpdecimal now builds properly even when <fenv.h> is not available (on i386), this commit fixes: http://autobuild.buildroot.org/results/b64/b64d5c941a7cac00619da3a0696939f86a8eafc2/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Add an option to disable decimal
|
|
|
|
This patch replaces the existing --with-system-libmpdec option with a
|
|
--with-libmpdec={system,builtin,none} option, which allows to tell
|
|
Python whether we want to use the system libmpdec (already installed),
|
|
the libmpdec builtin the Python sources, or no libmpdec at all.
