Suspected infinite loop. No value used in loop test (c) is modified by test or loop body. Assignment of int to char: c = getchar() Test expression for if is assignment expression: c = 'x' Test expression for if not boolean, type char: c = 'x' Fall through case (no preceding br...
include(CheckIPOSupported) check_ipo_supported(RESULT ipo_supported) if(ipo_supported) set(CMAKE_INTERPROCEDURAL_OPTIMIZATION True) endif() 正如你所见,我们不得不包含一个内置模块来获取check_ipo_supported()命令的访问权限。 检查支持的编译器功能 如我们之前讨论的,如果我们的构建失败,最好是早点失败,这样...
然后,我们不仅定义了测试,还定义了MEMORYCHECK_COMMAND: 代码语言:javascript 复制 find_program(MEMORYCHECK_COMMAND NAMES valgrind) set(MEMORYCHECK_COMMAND_OPTIONS "--trace-children=yes --leak-check=full") # add memcheck test action include(CTest) enable_testing() add_test( NAME cpp_test COMMAND $...
在以前版本的编译器中,此示例底部的静态断言可传递,因为 std::is_convertable<>::value 错误地设置为 true。 现在,std::is_convertable<>::value 正确设置为 false,使静态断言失败。 默认设置或已删除的日常复制和移动构造函数遵从访问说明符 对于默认设置或已删除的日常复制和移动构造函数的访问说明符,早期版本的...

The localeconv function declared in locale.h now works correctly when per-thread locale is enabled. In previous versions of the library, this function would return the lconv data for the global locale, not the thread's locale. If you use per-thread locales, you should check your use of loc...
