c++11 - CppuTest 使用 C++11 版本构建

Question

在Ubuntu下安装了g++ 4.9.0(实验)版本(我正在使用该版本提供的某些功能)

构建代码时，我使用脚本中的 cmake，并且它可以正确构建。下面的gcc包含g++的安装路径(/mnt...)

$_cmake_ $_dir_ -DCMAKE_CXX_COMPILER=${_gpp_} -DCMAKE_C_COMPILER=${_gcc_} -DCMAKE_BUILD_TYPE=${_build_} -DCMAKE_INSTALL_PREFIX=${_install_} -DBUILD_TESTING:BOOL=1 

现在，当我使用 CppuTest 为我的代码构建单元测试时，出现以下错误。

make all 
compiling UncrosserTest.cpp

make: *** [objs/AllTests/Uncrosser/UncrosserTest.o] Error 1

在 CppuTest makefile 中包含 CPPUTEST_CPPFLAGS += -std=c++1y。我猜想这个 makefile 中缺少一些标志，因为正如我所说，C++ 实验库在我的“常规”代码中正确构建。我缺少什么？

Answer 1

可能是包含问题，请参阅 CppUTest Manual - 部分与运算符新宏(STL!)冲突和与我自己的重载冲突!

TL;DR

在 UncrosserTest 中，在您的 CppUTest 之后添加包含内容。

而不是

#include <CppUTest/TestHarnes.h>
#include "whatever.h"

做

#include "whatever.h"
#include <CppUTest/TestHarnes.h>
