New submission from Jeffrey Armstrong: Within Modules/posixmodule.c:4914 (in 3.5.0a3), the preprocessor checks for compiler macros as such:
#if ( defined(__WATCOMC__) || defined(PYCC_VACPP) ) && !defined(__QNX__) result = mkdir(path->narrow); #else result = mkdir(path->narrow, mode); #endif The purpose of the code was to detect if we're compiling using Watcom, but not on QNX, or VisualAge as our compiler, where mkdir() wouldn't accept a mode. However, Watcom supports Linux as well and properly implements the mode argument, causing the compilation to fail. The proper check, rather than looking for "!defined(__QNX__)" would be "!defined(__UNIX__)," which would allow the code to properly compile using Watcom on either Linux or QNX: #if ( defined(__WATCOMC__) || defined(PYCC_VACPP) ) && !defined(__UNIX__) result = mkdir(path->narrow); #else result = mkdir(path->narrow, mode); #endif FYI, in Watcom, the __UNIX__ macro is defined on both Linux and QNX, so this change will not break code for people who are still using Watcom to build Python for QNX (which is probably nobody at all). There are two other places where the __QNX__ macro should be replaced in Modules/posixmodule.c, and the attached patch fixes both. ---------- components: Interpreter Core files: watcom_qnx_to_unix-3.5.0a3.patch keywords: patch messages: 240153 nosy: Jeffrey.Armstrong priority: normal severity: normal status: open title: Fix mkdir() call for Watcom compilers on UNIX-like platforms type: compile error versions: Python 3.5 Added file: http://bugs.python.org/file38843/watcom_qnx_to_unix-3.5.0a3.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23876> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
