From beb34a045838982179b5e223c41236d9293f4791 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Sat, 15 Jun 2019 15:19:58 +0200 Subject: SCons: Enable -Werror and -Wextra in 'dev' build option We're close to being able to compile all platforms with -Werror -Wextra, so it's best if developers use those options when compiling their code as those checks are also done on CI. Also enabled -Wduplicated-branches on GCC. --- SConstruct | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/SConstruct b/SConstruct index 17cf779d4a..ce2566559c 100644 --- a/SConstruct +++ b/SConstruct @@ -125,7 +125,7 @@ opts.Add(BoolVariable('verbose', "Enable verbose output for the compilation", Fa opts.Add(BoolVariable('progress', "Show a progress indicator during compilation", True)) opts.Add(EnumVariable('warnings', "Set the level of warnings emitted during compilation", 'all', ('extra', 'all', 'moderate', 'no'))) opts.Add(BoolVariable('werror', "Treat compiler warnings as errors.
