c++ - 这个 c++ html 整洁程序有什么问题

Question

我编译了一个 c tidy 程序，但出现错误，这是他们给出的示例程序

#include "tidy/tidy.h"
#include <stdio.h>
#include <errno.h>


int main(int argc, char **argv )
{
  const char* input = "<title>Foo</title><p>Foo!";
  TidyBuffer output = {0};
  TidyBuffer errbuf = {0};
  int rc = -1;
  Bool ok;

  TidyDoc tdoc = tidyCreate();                     // Initialize "document"
  printf( "Tidying:\t%s\n", input );

  ok = tidyOptSetBool( tdoc, TidyXhtmlOut, yes );  // Convert to XHTML
  if ( ok )
    rc = tidySetErrorBuffer( tdoc, &errbuf );      // Capture diagnostics
  if ( rc >= 0 )
    rc = tidyParseString( tdoc, input );           // Parse the input
  if ( rc >= 0 )
    rc = tidyCleanAndRepair( tdoc );               // Tidy it up!
  if ( rc >= 0 )
    rc = tidyRunDiagnostics( tdoc );               // Kvetch
  if ( rc > 1 )                                    // If error, force output.
    rc = ( tidyOptSetBool(tdoc, TidyForceOutput, yes) ? rc : -1 );
  if ( rc >= 0 )
    rc = tidySaveBuffer( tdoc, &output );          // Pretty Print

  if ( rc >= 0 )
  {
    if ( rc > 0 )
      printf( "\nDiagnostics:\n\n%s", errbuf.bp );
    printf( "\nAnd here is the result:\n\n%s", output.bp );
  }
  else
    printf( "A severe error (%d) occurred.\n", rc );

  tidyBufFree( &output );
  tidyBufFree( &errbuf );
  tidyRelease( tdoc );
  return rc;
}

错误

TidyBuffer 结构在 Tidy 库头 buffio.h 中声明，因此如果您也包含它，它应该可以工作。

顶部的包含应该如下所示:

#include <tidy.h>
#include <buffio.h>
#include <errno.h>
