From 3b51c53eca040217936e0ed2ebf8ab0555ffb058 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Fri, 4 Sep 2020 14:31:03 +0200 Subject: [PATCH] win32/build.py: add -D_FORTIFY_SOURCE=0 This fixes the Windows build. Linking failed because some packages (e.g. libFLAC) default to enabling `_FORTIFY_SOURCE`, which is broken in recent mingw versions (https://github.com/msys2/MINGW-packages/issues/5803). --- win32/build.py | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/win32/build.py b/win32/build.py index fb636ded5..8aa87e288 100755 --- a/win32/build.py +++ b/win32/build.py @@ -66,6 +66,11 @@ class CrossGccToolchain: ' -static-libstdc++ -static-libgcc' self.libs = '' + # Explicitly disable _FORTIFY_SOURCE because it is broken with + # mingw.
