c++ - cocos2d-x EditBox的简单例子，报错undefined reference to

Question

我在尝试使用 cocos2d-x 2.2.2、Fedora 20 和 Eclipse Kepler 将 EditBox 添加到示例游戏(由 create_project.py 创建)时遇到问题，

我在HelloWorldScene.cpp中添加了

using namespace cocos2d::extension;
using namespace cocos2d::gui;

和

CCEditBox *m_pEditName = CCEditBox::create(ccp(100,100),CCScale9Sprite::create("input_field.png"));
m_pEditName->setPosition(ccp(origin.x+visibleSize.width/2, origin.y+visibleSize.height*3/4));
m_pEditName->setFontColor(ccRED);
m_pEditName->setPlaceHolder("Name:");
m_pEditName->setMaxLength(8);
m_pEditName->setReturnType(kKeyboardReturnTypeDone);
addChild(m_pEditName);

添加到我的 HelloWorldScene.h

#include "cocos-ext.h"

出现错误

fatal error: cocos-ext.h: No such file or directory

我意识到编译器正试图在/usr/include 或/usr/local/include 中找到 .h 文件，所以我将其添加到我的 makefile

INCLUDES += -I$(COCOS_ROOT)/extensions
INCLUDES += -I$(COCOS_ROOT)/external/chipmunk/include/chipmunk

现在我又遇到了另一个错误，请看下面我的 makefile 和错误

生成文件

EXECUTABLE = thief

COCOS_ROOT = ../../..

INCLUDES = -I.. -I../Classes
INCLUDES += -I$(COCOS_ROOT)/extensions
INCLUDES += -I$(COCOS_ROOT)/external/chipmunk/include/chipmunk

SOURCES = main.cpp \
        ../Classes/AppDelegate.cpp \
        ../Classes/HelloWorldScene.cpp


include $(COCOS_ROOT)/cocos2dx/proj.linux/cocos2dx.mk

SHAREDLIBS += -lcocos2d
COCOS_LIBS = $(LIB_DIR)/libcocos2d.so

有人知道为什么会这样吗？

为了设置我的 cocos2d-x，我使用了这个说明 Building Cocos2d-x on RHEL / Fedora / CentOS Linux

谢谢

您需要在代码中添加“extensions/CocoStudio/GUI/Layouts/UILayoutDefine.cpp”或删除“cocos-ext.h”。
