papi_test.h:没有文件或目录

Question

我尝试使用PAPI代码将自己附加到已经运行的代码上，但是在编译时会出现一个错误papi_test.h :没有这样的文件或目录。

    #include "papi_test.h"
    #include <sys/ptrace.h>

            sleep ( 10 );
            retval = PAPI_stop( EventSet1, values[0] );
            if ( retval != PAPI_OK )

              test_fail_exit( __FILE__, __LINE__, "PAPI_cleanup_eventset", retval );

            retval = PAPI_destroy_eventset(&EventSet1);

            printf( "Test case: 3rd party attach start, stop.\n" );

            printf( "Test type    : \t           1\n" );
            printf( TAB1, "PAPI_LD_INS : \t", ( values[0] )[0] );
            printf( TAB1, "PAPI_SR_INS : \t", ( values[0] )[1] );
            printf( TAB1, "PAPI_BR_INS : \t", ( values[0] )[2] );

            printf( "Verification: none\n" );

            test_pass( __FILE__, values, num_tests );
            exit( 1 );
    }

即使在Papi-5.3.0/src/ctest文件夹中编译文件attach_target.c时，也会出现同样的错误。我希望使用PAPI监视已经在运行的C代码，并将计数器插入到它。

您缺少了包含路径(可能还有库路径)，使用：

gcc -I/path/to/papi/include/dir -c <filename> -L/path/to/papi/libs -lpapi

此外，您可能从Makefile中受益。Here在“如何编写一个简单的Makefile”中给出了很好的解释，大概是从make开始所需的一切。
