[issue10782] Not possible to cross-compile due to poor detection of %lld support in printf

Post #1 of 4 (3923 views)

New submission from Ben Gamari <bgamari@gmail.com>:

Configure.in assumes that %lld is not supported by printf if cross-compiling. This causes build errors in pyport.h,

In file included from Include/Python.h:58:0,
from Parser/parser.c:8:
Include/pyport.h:243:13: error: #error "This platform's pyconfig.h needs to define PY_FORMAT_LONG_LONG"
...

What is one supposed to do about this short of changing the configure script to assume support by default.

Use config.cache to set ac_cv_have_long_long_format

Requests for information should go to python-list or other support forums. That said, does the response settle this issue, so that it can be closed, or is there still a claim that something should be changed in the Python repository?

Well, I'm not convinced that overriding config.cache is the best solution, but I am not really sure what else can be done. So far I've just been carrying a patch which changes configure.in, but this is clearly an awful hack.
