我有兩個簡單的文件:升壓試驗 - '未定義的參考' 錯誤
runner.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()
進行編譯,我使用:
$ g++ -I/e/code/boost_1_52_0 -o runner -lboost_unit_test_framework runner.cpp test1.cpp
我得到以下錯誤:

我在MinGW上使用g ++ 4.7.2,boost 1.52.0。
僅在嘗試編譯test1.cpp
時出現同樣的錯誤 - 「多主定義」除外。
我在官方文檔中閱讀了很長一段時間,但在關於鏈接選項的細節上很少見。當我編譯提升庫時,除了unit_test_framework
,我也得到了prg_exec_monitor
和test_exec_monitor
;也許我應該連接這些莫名其妙?我嘗試了很多組合,但都導致了某種未定義的參考鏈接器錯誤。
完成升壓產生的庫列表 - 我把它們都在項目的根:
libboost_prg_exec_monitor-mgw47-mt-1_52.a
libboost_prg_exec_monitor-mgw47-mt-1_52.dll
libboost_prg_exec_monitor-mgw47-mt-1_52.dll.a
libboost_prg_exec_monitor-mgw47-mt-d-1_52.a
libboost_prg_exec_monitor-mgw47-mt-d-1_52.dll
libboost_prg_exec_monitor-mgw47-mt-d-1_52.dll.a
libboost_test_exec_monitor-mgw47-mt-1_52.a
libboost_test_exec_monitor-mgw47-mt-d-1_52.a
libboost_unit_test_framework-mgw47-mt-1_52.a
libboost_unit_test_framework-mgw47-mt-1_52.dll
libboost_unit_test_framework-mgw47-mt-1_52.dll.a
libboost_unit_test_framework-mgw47-mt-d-1_52.a
libboost_unit_test_framework-mgw47-mt-d-1_52.dll
libboost_unit_test_framework-mgw47-mt-d-1_52.dll.a
使用g ++,你需要把你的庫(-lwhatever)源後或目標文件(即'g ++ -I/e/code/boost_1_52_0 -o runner runner.cpp test1.cpp -lboost_unit_test_framework')。鏈接[here](http://www.network-theory.co.uk/docs/gccintro/gccintro_18.html)。有可能你還需要爲你的'-I/e/code/boost_1_52_0'增加一個'-L/path/to/libraries'。 – 2012-12-07 18:18:05
[This answer](http:// stackoverflow。com/a/2907582/1252091)似乎與你所做的非常相似。 – 2012-12-07 18:33:06
@llonesmiz確實,把對象工作後的lib。 '-L.'也是需要的,並且lib需要作爲'-lboost_unit_test_framework-mgw47-mt-1_52'傳遞。將它作爲'-lboost_unit_test_framework'傳遞會導致鏈接錯誤。但是,當我懷疑它可能找不到lib時,我給了'-lfoo'之類的東西,它抱怨沒有這樣的lib存在。在查閱了[這個頁面](http://www.mingw.org/wiki/HOWTO_Specify_the_Location_of_External_Libraries_for_use_with_MinGW)關於默認的MinGW lib路徑之後,我發現在這些文件夾中有一個'libboost_unit_test_framework.a'。 –
