Message179187
The Py_ARRAY_LENGTH macro (Include/pymacro.h:36) checks to see if using GCC by simply looking for __GCC__ being defined. If so, it uses the GCC extension function "__builtin_types_compatible_p." However, this function was not introduced until GCC 3.1. This simple check for a GCC compiler causes the Python build to fail on GCC < 3.1 (2.95 for example).
The check should actually be:
#if (defined(__GNUC__) && !defined(__STRICT_ANSI__) && \
((__GNUC__ == 3) && (__GNU_MINOR__) >= 1) || (__GNUC__ >= 4)))
Similar checks are made in other locations in the core library, just not here.
This bug was discovered while attempting a build on m68k-atari-mint, which relies on GCC 2.95.3. Other systems may also be using this compiler still. |
