Question

以下是我在Eclipse CDT中使用的代码（来自官方提升文档http://www.boost.org/doc/libs/1_55_0/libs/test/doc/html/tutorials/hello-the-testing-world.html）：

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

int add(int i, int j) {
   return i + j;
}

BOOST_AUTO_TEST_CASE( my_test ) {
   // seven ways to detect and report the same error:
   BOOST_CHECK(add(2, 2) == 4);        // #1 continues on error

   BOOST_REQUIRE(add(2, 2) == 4);      // #2 throws on error

   if (add(2, 2) != 4)
      BOOST_ERROR("Ouch...");            // #3 continues on error

   if (add(2, 2) != 4)
      BOOST_FAIL("Ouch...");             // #4 throws on error

   if (add(2, 2) != 4)
      throw "Ouch..."; // #5 throws on error

   BOOST_CHECK_MESSAGE(add(2, 2) == 4,  // #6 continues on error
   "add(..) result: " << add( 2,2 ));

   BOOST_CHECK_EQUAL(add(2, 2), 4);      // #7 continues on error
}

当我尝试在Eclipse或终端中构建它时，我收到一条关于缺少入口点或主要功能的错误消息：

在代码中放置一个main函数会导致程序构建正常，但之后会完全跳过测试。我使用synaptic包管理器安装了boost测试，所以它应该是即插即用减去我指定库（-l）的部分为boost_unit_test_framework。

我已经能够获得boost / test / minimal.hpp链接并且工作正常，但不幸的是我还没有得到boost / test / unit_test.hpp在Eclipse中很好地运行单元测试输出显示在C / C ++单元视图中。我尝试过几个官方和非正式的文档/教程，并且还没有成功。我试图在Eclipse中开始进行单元测试，这与在Eclipse中使用JUnit的舒适性有些相似。任何帮助或建议表示赞赏。感谢。

想出来。事实证明我应该避免通过包管理器安装框架库。最好从源代码安装，以便了解所有内容。这两个文档有所帮助：

以及处理共享库的一般情况（即在bjam安装阶段之后）：

http://www.cprogramming.com/tutorial/shared-libraries-linux-gcc.html

我不确定软件包管理器放置库的位置，但我需要在链接时和运行时验证链接的完整性，确保将库文件放在/ usr / local / lib中然后跟进ldconfig。
