Question

尝试使用cocos2d-x 2.2.2，Fedora 20和Eclipse Kepler将示例游戏（由create_project.py创建）添加到EditBox时，我遇到了一个问题，

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"

并收到错误

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，所以我添加到了我的makefile

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

现在我收到另一个错误，请参阅下面的makefile和错误

有谁知道为什么会这样？

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

您需要添加＆＃34;扩展/ CocoStudio / GUI / Layouts / UILayoutDefine.cpp＆＃34;或删除＆＃34; cocos-ext.h＆＃34;从你的代码。
