cocos2d-x - compiling the example

Sheado

Hi All,

I'd like to try out the cocos2d-x example to see if Spine is a good fit for my project.

When compiling (in linux) I get the following error:
../Classes/spine/spine-cocos2dx.h:46:45: error: expected class-name before ‘,’ token

I think it's complaining about CCNodeRGBA. I'm using cocos2d-x version 2.1.1
Is a different version required? Or is CCNodeRGBA defined elsewhere?

Thanks!

I used cocos2d-2.1rc0-x-2.1.2. Did you put cocos2dx in the "spine-cocos2dx/cocos2dx" directory? Note that I just committed a total rewrite of spine-cocos2dx tonight, so you might want to grab the latest from git again.

Ah, thanks for the quick reply.
It looks like CCNodeRGBA doesn't exist in 2.1.1. Just upgraded to 2.1.2 and it's there now. I expect it will compile fine now.

thanks,

I added a new class named *CCNodeRGBA"

//.h{{
//////////////
namespace cocos2d
{
class CCNodeRGBA :public cocos2d::CCNode, public cocos2d::CCRGBAProtocol
{
public:
virtual void setOpacityModifyRGB(bool bValue);
virtual bool isOpacityModifyRGB(void);
private:
/** conforms to CCRGBAProtocol protocol */
CC_PROPERTY(GLubyte, m_cOpacity, Opacity)
/** conforms to CCRGBAProtocol protocol */
CC_PROPERTY_PASS_BY_REF(ccColor3B, m_tColor, Color)
/** conforms to CCRGBAProtocol protocol */
bool m_bIsOpacityModifyRGB;
};
};

//.h }}

and
//.cpp

// Opacity and RGB color protocol
/// opacity getter
GLubyte CCNodeRGBA::getOpacity()
{
return m_cOpacity;
}
/// opacity setter
void CCNodeRGBA::setOpacity(GLubyte var)
{
m_cOpacity = var;
// updateColor();
}

/// color getter
const ccColor3B& CCNodeRGBA::getColor()
{
return m_tColor;
}

/// color setter
void CCNodeRGBA::setColor(const ccColor3B& var)
{
m_tColor = var;
//updateColor();
}

/////////////////////////////////////////////

So I can compile the demo.

Probably better to just use the right version of cocos2dx...

stone

which verion of cocos2d-x?
I am usring the cocos2d-2.1beta3-x-2.1.1.

Nate

As mentioned, I used cocos2d-2.1rc0-x-2.1.2. Use the latest.

Hi guys,

I am similarly trying to compile on linux but not sure quite how to get setup. I am a beginner, so please excuse how obvious the answer may be...

Basically, as a test setup, I am trying to copy the spine-runtimes/spine-cocos2dx sample into my own existing project. This is my directory layout:
app_root/

Classes

ExampleLayer.cpp
...
spine/

CCSkeleton.cpp
...
cocos_root
proj.linux
Makefile

My Makefile looks like this:

EXECUTABLE = SpineTest

SOURCES = main.cpp \
        ../Classes/spine/spine-cocos2dx.cpp \
        ../Classes/spine/CCSkeleton.cpp \
        ../Classes/spine/CCSkeletonAnimation.cpp \
        ../Classes/AppDelegate.cpp \
        ../Classes/ExampleLayer.cpp 


COCOS_ROOT = ../cocos_root

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

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


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

STATICLIBS += \
    $(STATICLIBS_DIR)/libcurl.a \
    $(LIB_DIR)/libextension.a \
    $(LIB_DIR)/libbox2d.a \
    $(LIB_DIR)/libchipmunk.a

$(TARGET): $(OBJECTS) $(STATICLIBS) $(COCOS_LIBS) $(CORE_MAKEFILE_LIST)
    @mkdir -p $(@D)
    $(LOG_LINK)$(CXX) $(CXXFLAGS) $(OBJECTS) -o $@ $(SHAREDLIBS) $(STATICLIBS)

$(OBJ_DIR)/%.o: %.cpp $(CORE_MAKEFILE_LIST)
    @mkdir -p $(@D)
    $(LOG_CXX)$(CXX) $(CXXFLAGS) $(INCLUDES) $(DEFINES) $(VISIBILITY) -c $< -o $@

$(OBJ_DIR)/%.o: ../%.cpp $(CORE_MAKEFILE_LIST)
    @mkdir -p $(@D)
    $(LOG_CXX)$(CXX) $(CXXFLAGS) $(INCLUDES) $(DEFINES) $(VISIBILITY) -c $< -o $@

I run the following to compile:

export MAKEFLAGS=-j10
make PLATFORM=linux DEBUG=1 clean
make PLATFORM=linux DEBUG=1 all

And I run into issues trying to reference spine types:
../Classes/spine/CCSkeleton.h:41:2: error: ‘Skeleton’ does not name a type

Any help is greatly appreciated. I am very excited to start using Spine
Thanks

I was able to compile and run the sample after editing CCSkeleton.h to include

using namespace cocos2d::extension;
