Question

私はこのcmakeのリストを持っています問題は、私は、コードのこの作品に対するエラーメッセージerror: undefined reference to Pa_GetVersion'` を取得していますということですrecord.h

#ifndef RECORD_H 
#define RECORD_H 
#include <iostream> 
#include "portaudio.h" 
class record 
{ 
public: 
    record(); 
    void example(); 
}; 

#endif // RECORD_H 

main.cppに：

#include <iostream> 
#include "record.h" 

using namespace std; 

int main() 
{ 
    record test; 
    test.example(); 

    cout << "Hello World!" << endl; 
    return 0; 
}

which code必要なファイルが存在し、CMakeListが追加されたので、賢明ではありません。だから問題は見えません。いくつかのことを変更しました

Answer 1

あなたCMakeのスクリプトは、あなたをリンクすることを指示する、「target_link_libraries」行が含まれていないようですプロジェクトは、portaudioライブラリに対して実行可能です。 'add_dependencies'行は、portaudioが最初に構築されているかどうかを確認するだけで、実際にはそれとリンクしません。次のようなものを追加すること

試してみてください。

target_link_libraries(${PROJECT_NAME} portaudio)
