我有两个简单的文件:
亚军.cpp:
#define BOOST_TEST_DYN_LINK
#define BOOST_TEST_MODULE Main
#include <boost/test/unit_test.hpp>
和 test1.cpp:
#define BOOST_TEST_DYN_LINK
#ifdef STAND_ALONE
# define BOOST_TEST_MODULE Main
#endif
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_SUITE( Foo)
BOOST_AUTO_TEST_CASE( TestSomething )
{
BOOST_CHECK( true );
}
BOOST_AUTO_TEST_SUITE_END()
要编译,我正在使用:
$ g++ -I/e/code/boost_1_52_0 -o runner -lboost_unit_test_framework runner.cpp test1.cpp
我收到以下错误:

我在 MinGW 上使用 g++ 4.7.2,boost 1.52.0。
仅尝试编译时,我会遇到相同的错误test1.cpp
-“多个主要定义”除外。
我仔细阅读了官方文档很长一段时间,但是关于链接选项的细节很少。当我编译 boost 库时,除此之外unit_test_framework
,我还得到了prg_exec_monitor
and test_exec_monitor
; 也许我应该以某种方式链接这些?我尝试了很多组合,但都导致了某种未定义的引用链接器错误。
