我試圖使用通過柯南安裝的gtest,但結束了未定義的參考鏈接器錯誤。這個問題或多或少是跟進this stackoverflow question。但我認爲提供的例子很簡單。我使用gcc 6.3編譯了最新的arch linux x64。GTest與柯南一起安裝:未定義的參考
會有一些C + +版本的錯位?還是你有任何其他想法來解決這個問題?
我會提供以下我的源代碼:
目錄樹:
tree
.
├── CMakeLists.txt
├── conanfile.txt
└── main.cpp
main.cpp中:
#include <iostream>
#include <gtest/gtest.h>
class TestFixture : public ::testing::Test {
protected:
void SetUp(){
std::cout << "SetUp()" << std::endl;
}
void TearDown(){
std::cout << "TearDown()" << std::endl;
}
};
TEST_F (TestFixture, shouldCompile) {
std::cout << "shouldCompile" << std::endl;
ASSERT_TRUE(true); // works, maybe optimized out?
ASSERT_TRUE("hi" == "hallo"); // undefined reference
}
int main(int argc, char **argv) {
::testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
的的CMakeLists.txt:
project(ConanGtestExample)
cmake_minimum_required(VERSION 2.8.12)
set(CMAKE_CXX_STANDARD 11)
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake)
conan_basic_setup()
# Necessary to compile gtest
# - dependencies and final build
# need to be compiled with same
# build type. Otherwise linker
# error will occure.
set(CMAKE_BUILD_TYPE Release)
add_executable(main main.cpp)
target_link_libraries(main ${CONAN_LIBS})
的conanfile.txt:
[requires]
gtest/[email protected]/stable
[generators]
cmake
我試圖建立與下面的命令的項目:
mkdir build
cd build
conan install -s build_type=Release .. --build=missing
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .
未定義參考輸出:

我剛想回答這個問題,你快了秒!事實是,conan使用默認的''libstdC++'',你可以在你的''/.conan/conan.conf''中檢查它,因爲它提供了更廣泛的兼容性。您可能想閱讀http://blog.conan.io/2016/03/22/From-CMake-syntax-to-libstdc++-ABI-incompatibiliy-migrations-are-always-hard.html。 TL; DR:使用''libstdC++'',你可以在大多數發行版甚至更老的發行版上運行bin,甚至gcc> 5.1,它們都帶有libstdC++(不是11) –
