C ++ ошибка "X не был объявлен в этой области"

0 голосов
/ 10 апреля 2011

, поэтому я скачал этот шахматный движок: http://www.ascotti.org/programming/chess/chess.htm

и попытался скомпилировать и запустить его с помощью eclipse ... но затем он выдал целую кучу ошибок ...

среди них много ошибок «X не был объявлен в этой области» в нескольких файлах, включая bitboard.h, hash.h и pawnhash.h ....

что означает эта ошибка и каквы решаете эти ошибки из этого кода?

также много Uint64 не было объявлено ошибок, таких как в bitboard.h ...

еще раз, почему это так, и как бы вы решили это?

спасибо заранее

Я только что скачал исходный код, и мне пришлось его пропатчить, чтобы скомпилировать: 

diff --git a/pgn_lex.h b/pgn_lex.h
--- a/pgn_lex.h
+++ b/pgn_lex.h
@@ -74,7 +74,7 @@ public:

         @return token identifier
     */
-    PGNTokenId PGNLex::getNextToken();
+    PGNTokenId getNextToken();

     /** Returns the current token identifier. */
     PGNTokenId tokenId() const {

Надеюсь, это поможет

Вам необходимо указать Uint64 и Uint32 для вашей платформы (вы не упоминаете, что это в вашем вопросе).

Для этого вам нужно взглянуть на platform.h во включенном источнике.

Похоже, что вы используете какую-то версию GCC в какой-то версии Windows, поэтому Я подозреваю, все, что вам нужно сделать, это предоставить -DWIN_I386 до g++. Я не знаю, как это сделать с вашей средой сборки. Если бы вы использовали прилагаемый Makefile, вы бы взяли следующую строку ... 

CC_FLAGS = -Wall -DEOF_AS_INPUT -DGCC -DLINUX_I386 -O2

... и заменить LINUX на WIN.

Вы найдете, что с этим исправлено, у вас есть более управляемый список предупреждений и ошибок. ответ sehe исправляет одну из ошибок, с которыми я столкнулся при построении i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664). Вот патч , показывающий исправления для моей сборки.

Как только вы исправите код для своей платформы, вы должны отправить патч Алессандро Скотти.

Наслаждайтесь!

Это означает, что идентификатор, использованный в коде, не был объявлен ранее.Это может быть что-нибудь действительно переменное, имя типа, что-то еще.Однако если ожидается, что рассматриваемый код будет действительным, вероятно, отсутствует некоторая библиотечная зависимость.Проверьте на более ранние ошибки.Среди них должно быть несколько «abc.h - Нет такого файла или каталога».Также прочитайте о необходимых внешних библиотеках, необходимых для компиляции загруженного кода и их установки.
