From 5e94e315119117898ce1a2798641848f61d796b1 Mon Sep 17 00:00:00 2001 From: Mingli Yu Date: Thu, 9 Jul 2020 07:58:44 +0000 Subject: [PATCH] configure.ac: define a path for profile data There comes below error when use ccache 3.7.10 to compile python3 and check [1] for more details. | Python-3.8.3/Modules/_contextvarsmodule.c:43:1: error: source locations for function 'PyInit__contextvars' have changed, the profile data may be out of date [-Werror=coverage-mismatch] That's because the logic for profile directory changes a little in [2] after ccache upgrades to 3.7.10. So define a profile directory path accordingly to fix the above error.
