From d98739ceaac1c477879b9c4fba89ea76dba2d539 Mon Sep 17 00:00:00 2001 From: axxel Date: Sun, 22 Sep 2024 22:39:11 +0200 Subject: [PATCH] cmake: switch to c++-20 by default for the core library I finally accept the incurred performance penalty from the position independent DataMatrix detection by default. This is finally fixing #386. It also (sufficiently) fixes #822 and thereby supersedes #836. --- CMakeLists.txt | 4 +++- 1 file changed, 3 insertions(+), 1 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index b602712d79..fee4c68cdc 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -71,7 +71,9 @@ if(NOT ZXING_DEPENDENCIES IN_LIST ZXING_DEPENDENCIES_LIST) endif() if (NOT DEFINED CMAKE_CXX_STANDARD) - set (CMAKE_CXX_STANDARD 17) + set (CMAKE_CXX_STANDARD 20) + # Allow the fallback to earlier versions if the compiler does not support it. + set(CMAKE_CXX_STANDARD_REQUIRED OFF) endif() if (NOT DEFINED CMAKE_CXX_EXTENSIONS) set (CMAKE_CXX_EXTENSIONS OFF)
