如何在jenkins中使用GoogleMock？

Question

我在CentOS虛擬機上安裝了Jenkins。 現在，我想使用模擬（Google模擬）運行unittests（谷歌測試）。 我嘗試安裝這里描述的框架。 （在我的lubuntu機器上，使用這些步驟，所有程序運行都沒有問題）

當我嘗試構建時：

g++ -O2 -pthread -Werror -Wall -o unitTest DriveTest.cpp Drive.cpp PWM.cpp -lgtest -lgtest_main -lgmock

我收到以下錯誤：

 make unitTest
 g++ -O2 -std=c++0x -pthread -Werror -Wall -o unitTest DriveTest.cpp Drive.cpp PWM.cpp -lgtest -lgtest_main -lgmock

我怎樣才能解決這個問題？

Answer 1

您在CentOS上擁有的GCC版本似乎太舊了，無法處理這些可變參數模板。 我希望4.4.7可以使它們可用，因為狀態頁面似乎表明它們應該可用。 但是， 這個問題似乎可以證實這種情況。

我的建議是使用dev-toolset 2 repo升級編譯器。 這將使您能夠訪問CentOS 6上的GCC 4.8（我猜您使用的是GCC版本），但具有修改過的stdlib，這意味着您的二進制文件仍將使用CentOS / RedHat 5中的運行時運行。
