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) 上并安装了XCode 4.5。
该程序在使用GCC编译时可以工作,例如,
gcc test.cpp -lboost_unit_test_framework-mt -lstdc++
但是当使用 Apple Clang 4.1 (tags/Apple/clang-421.11.65) (基于LLVM 3.1svn)编译时它会崩溃
clang -std=c++11 -stdlib=libc++ -lc++ test.cpp -lboost_unit_test_framework-mt
我使用的是使用 BREW 安装的 Boost 1.51.0。使用 Clang 重新编译 Boost 没有帮助。
这个谜团有解决办法吗?
