Arnaldo Carvalho de Melo c6b1616f54 perf scripting python: Avoid declaring function pointers with a visibility attribute ... commit d0e7b0c71f upstream. To avoid this: util/scripting-engines/trace-event-python.c: In function 'python_start_script': util/scripting-engines/trace-event-python.c:1595:2: error: 'visibility' attribute ignored [-Werror=attributes] 1595 | PyMODINIT_FUNC (*initfunc)(void); | ^~~~~~~~~~~~~~ That started breaking when building with PYTHON=python3 and these gcc versions (I haven't checked with the clang ones, maybe it breaks there as well): # export PERF_TARBALL=http://192.168.86.5/perf/perf-5.9.0.tar.xz # dm fedora:33 fedora:rawhide 1 107.80 fedora:33 : Ok gcc (GCC) 10.2.1 20201005 (Red Hat 10.2.1-5), clang version 11.0.0 (Fedora 11.0.0-1.fc33) 2 92.47 fedora:rawhide : Ok gcc (GCC) 10.2.1 20201016 (Red Hat 10.2.1-6), clang version 11.0.0 (Fedora 11.0.0-1.fc34) # Avoid that by ditching that 'initfunc' function pointer with its: #define Py_EXPORTED_SYMBOL _attribute_ ((visibility ("default"))) #define PyMODINIT_FUNC Py_EXPORTED_SYMBOL PyObject* And just call PyImport_AppendInittab() at the end of the ifdef python3 block with the functions that were being attributed to that initfunc.
