googletest＆cmake - アーキテクチャx86_64の未定義シンボル

Question

私はシンプルなC++プロジェクトに取り組んでおり、単体テスト、特にgoogletestを使いたいと思っていました。まず、私のプロジェクトの構造はhttps://github.com/snikulov/google-test-examplesです。私がそれをクローンしてそれをテストしたとき、それは完全に機能しました。私はその後、私のプロジェクトに必要なコンポーネントを移動し、私は次のリンカエラーを取得：

Undefined symbols for architecture x86_64: 
    "Vector::Vector(int, float*)", referenced from: 
     cpp_vector_test_vector_operator_adder_Test::TestBody() in cpp_vector_test.cc.o 
    "Vector::~Vector()", referenced from: 
     cpp_vector_test_vector_operator_adder_Test::TestBody() in cpp_vector_test.cc.o 
    "Vector::operator==(Vector)", referenced from: 
     cpp_vector_test_vector_operator_adder_Test::TestBody() in cpp_vector_test.cc.o 
    "Vector::operator+(Vector)", referenced from: 
     cpp_vector_test_vector_operator_adder_Test::TestBody() in cpp_vector_test.cc.o 
ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

私が間に一日か二日で数時間のためにこれを通じて取り組んできましたし、運がなかったしています。私のプロジェクトはhttps://github.com/bi3mer/Bragiです。私はそうのようなcmakeの実行しようとしたしばらくcmakeの設定で遊んでてきた：

cmake -DBUILD_SHARED_LIBS=ON .. 

と定期：

cmake .. 

私を投げている、特に奇数のノートがあればということです私は私のようなテストコードを持っています：

#include "Vector.h" 
#include "gtest/gtest.h" 

TEST(cpp_vector_test, vector_operator_adder) 
{ 
    EXPECT_EQ(true, true); 
} 

それは正常に動作します。私は一度クラスをインスタンス化しようとすると、エラーが発生します。

#include "Vector.h" 
#include "gtest/gtest.h" 

TEST(cpp_vector_test, vector_operator_adder) 
{ 
    Vector test = Vector(3); // throws error 
    EXPECT_EQ(true, true); 
} 

私はまた、このようなgtest: Undefined symbols for architecture x86_64 error with clang++ and std::vectorなどの他のスレッドを見てきたが、私はconfigureスクリプトから来ている見当がつかない。

コンパイラの不一致が起こっているように見えたすべてに基づいて、私は読んだことのあるものすべてに基づいて修正する方法がわかりません。

私はクローンを作成する、あなたが役立つことを願っ：

git clone https://github.com/bi3mer/Bragi.git 

私は、これはファイルやeveryingに貼り付けるよりも簡単である把握。私はあなたが助けてくれることを願っています。お手伝いありがとう。

全ファイルがgithubの上で見ることができます：それは、SRCに

file(GLOB SRC_FILES ${PROJECT_SOURCE_DIR}/src/*.cc) 

を追加し、実行可能

add_executable(${PROJECT_TEST_NAME} ${TEST_SRC_FILES} ${SRC_FILES}) 

にそれを含めているに沸く何https://github.com/bi3mer/Bragi/blob/master/CMakeLists.txt#L27

私が持っていた例は、私を捨てたこの一歩を含んでいませんでした。

ありがとうございました。
