鏈接錯誤與cppunit，cmake，ubuntu

對不起，這可能是一個完整的noob問題，但我越來越絕望。我想獲得的CppUnit與KDevelop的/ CMake的Ubuntu上運行鏈接錯誤與cppunit，cmake，ubuntu

我安裝libcppunit-dev的：

[email protected]:~$ apt-cache policy libcppunit-dev 
libcppunit-dev: 
    Installed: 1.12.1-4 
    Candidate: 1.12.1-4 
    Version table: 
*** 1.12.1-4 0 
     500 http://at.archive.ubuntu.com/ubuntu/ precise/main i386 Packages 
     100 /var/lib/dpkg/status

我的CMakeLists.txt看起來是這樣的：

project(simpletest) 

include_directories(/usr/local/include/) 
link_directories(/usr/lib/) 

add_executable(simpletest main.cpp) 
LINK_LIBRARIES(simpletest cppunit)

和我SimpleTest的這樣：

#include <iostream> 

#include <cppunit/ui/text/TestRunner.h> 
#include <cppunit/CompilerOutputter.h> 
#include <cppunit/TestFixture.h> 
#include <cppunit/extensions/HelperMacros.h> 

int main() { 
    CppUnit::Test* suite = CppUnit::TestFactoryRegistry::getRegistry().makeTest(); 

    CppUnit::TextUi::TestRunner runner; 
    runner.addTest(suite); 
    runner.setOutputter(new CppUnit::CompilerOutputter(&runner.result(), std::cerr)); 

    return runner.run() ? 0 : 1; 
}

如果我只是做了：

g++ simpletest.cpp -lcppunit -o simpletest.bin

一切都編譯和鏈接就好了。但是，如果我生成使用CMake的，我得到的鏈接錯誤：

由於其工作調用g當++直接我認爲所有的圖書館都存在和運作（沒有編譯器hickup等），但問題是我的CMake文件。 - 圖書館宣言應如何運作 - 例如是名爲libcppunit或cppunit的庫。我認爲我只是犯了一些愚蠢的錯誤，但任何幫助將不勝感激。

您已通過徹底閱讀[**什麼是未定義的引用/無法解析的外部符號錯誤，以及如何解決它？**]，檢查了此錯誤的所有可能原因（http://stackoverflow.com/questions/ 12573816/what-is-unde-undefined-reference-unresolved-external-symbol-error-and-how-do-i-fix），是嗎？ – 2014-10-28 21:51:31

感謝您的鏈接。我假設我的問題是列表中的第一個（未能鏈接到適當的庫/對象文件或編譯實現文件）。我只是不知道如何告訴Cmake文件在哪裏可以找到正確的庫文件（直接使用g ++它與-lcppunit一起工作）。任何想法，我缺少什麼？ – markus 2014-10-28 22:01:08

好吧，我剛剛發現了錯誤。我用LINK_LIBRARIES代替target_link_libraries

此的CMakeLists.txt非常有效：

cmake_minimum_required(VERSION 2.8) 
project(simpletest) 

add_executable(simpletest main.cpp) 
target_link_libraries (simpletest cppunit)

@πάνταῥεῖ感謝出色的鏈路

我不確定你是否有同樣的問題（鏈接器沒有找到cppunit目標文件）或想共享一個答案，以防萬一。我的解決方案是使用target_link_libraries（yourTarget cppunit）而不是LINK_LIBRARIES。之後，一切正常。 – markus 2014-11-04 15:57:27
