From: Simon Marchi Date: Thu, 23 Feb 2023 19:29:42 +0000 (-0500) Subject: bt2: ignore -Wredundant-decls warning X-Git-Url: https://git.efficios.com/?p=babeltrace.git;a=commitdiff_plain;h=92e41f9132ac72f234deb2f39f2eae0b1858cfc0 bt2: ignore -Wredundant-decls warning The ppc builder on the CI, which uses Python 3.11 + gcc 12.2.0, shows this warning: In file included from /usr/include/python3.11/Python.h:91, from bt2/native_bt.c:168: /usr/include/python3.11/modsupport.h:37:24: error: redundant redeclaration of ‘_Py_BuildValue_SizeT’ [-Werror=redundant-decls] 37 | PyAPI_FUNC(PyObject *) _Py_BuildValue_SizeT(const char *, ...); | ^~~~~~~~~~~~~~~~~~~~ /usr/include/python3.11/modsupport.h:20:41: note: previous declaration of ‘_Py_BuildValue_SizeT’ with type ‘PyObject *(const char *, ...)’ {aka ‘struct _object *(const char *, ...)’} 20 | #define Py_BuildValue _Py_BuildValue_SizeT | ^~~~~~~~~~~~~~~~~~~~ /usr/include/python3.11/modsupport.h:36:24: note: in expansion of macro ‘Py_BuildValue’ 36 | PyAPI_FUNC(PyObject *) Py_BuildValue(const char *, ...); | ^~~~~~~~~~~~~ I tried fixing it by placing some push/ignored/pop diagnostic pragmas in the SWIG sections %begin and %runtime, which would be around the Python.h including in the generated native_bt.c file, but it doesn't silence the warning for some reason. Ignore the warning for the whole native_bt.c compilation instead.
