使用Clang 4.1(LLVM 3.1svn)退出测试时崩溃

Question

考虑这个简单的程序:

#include <string>
#include <iostream>

#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE "MyTest"
#include <boost/test/unit_test.hpp>

using namespace std;

template<char* S>
void Test()
{
    BOOST_REQUIRE("Boom!" != string(S));
}

char bang[] = "Bang!";

BOOST_AUTO_TEST_CASE(Boom)
{
    char boom[] = "Boom!";
    Test<bang>();
}

我在Mac OS X v10.8.2(Mountain Lion)上安装了XCode 4.5.

例如,在使用GCC编译时,该程序可以正常工作

gcc test.cpp -lboost_unit_test_framework-mt -lstdc++

但是在使用Apple Clang 4.1(标签/ Apple/clang-421.11.65)编译时崩溃(基于LLVM 3.1svn)

clang -std=c++11 -stdlib=libc++ -lc++ test.cpp -lboost_unit_test_framework-mt

我使用的是Boost 1.51.0,使用BREW安装.使用Clang重新编译Boost没有帮助.

有这个谜的解决方案吗？

Answer 1

使用C++ 11选项重新编译Boost就可以了.

./bootstrap.sh --with-toolset=clang --prefix=/usr/local
sudo ./b2 install toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++" threading=multi

我./b2 install上次错误地使用了,但安装步骤似乎在安装之前构建了一些库.

Answer 2

以下似乎可行，但您可能需要其他参数。

USER (~/tmp)
$ clang++ -pedantic test.cpp -lboost_unit_test_framework-mt 

USER (~/tmp)
$ ./a.out
