Directives want to compile from 3.17.2 to 4.0

cocos2d-x
#1

Hi all id like to port to cocos2dx V4 and its not too much trouble but want to keep support for V 3.17.2
I see this for target build but is there one for the Version’s of Cocos 3.17.2 detection
#if (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32) || (CC_TARGET_PLATFORM == CC_PLATFORM_MAC) || (CC_TARGET_PLATFORM == CC_PLATFORM_LINUX)

many thanks in advance.
also not sounding too silly was compiling for win32 theirs no WebView is there still and inbuilt browser for
Cocos or we just launching Internet explore external.

I don’t understand why you want to do this. Can you explain more of your use case?

Are you trying to keep the same code base and have v3 and v4 specific functionality?

Perhaps you can check the version of Cocos being used by using this:

#3

Certain sections of the CMakeLists.txt will be differnet between v3.17.2 and v4, so use this to get the version:

get_target_property(COCOS2D_X_VERSION cocos2d VERSION)

For instance:

get_target_property(COCOS2D_X_VERSION cocos2d VERSION)

if (COCOS2D_X_VERSION VERSION_GREATER_EQUAL 4.0.0)
    if(APPLE)
        set_target_properties(${APP_NAME} PROPERTIES RESOURCE "${APP_UI_RES}")

        if(MACOSX)
            set_target_properties(${APP_NAME} PROPERTIES MACOSX_BUNDLE_INFO_PLIST "${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/mac/Info.plist")
        elseif(IOS)
            set_target_properties(${APP_NAME} PROPERTIES MACOSX_BUNDLE_INFO_PLIST "${CMAKE_CURRENT_SOURCE_DIR}/proj.ios_mac/ios/Info.plist")
            set_xcode_property(${APP_NAME} ASSETCATALOG_COMPILER_APPICON_NAME "AppIcon")
            set_xcode_property(${APP_NAME} XCODE_ATTRIBUTE_TARGETED_DEVICE_FAMILY "1,2") # iphone, ipad

            set_target_properties(${APP_NAME} PROPERTIES

                XCODE_ATTRIBUTE_VALID_ARCHS[sdk=iphonesimulator*] x86_64
                )
        endif()

Thanks yeah did not think to look in the CMakeLists it’s all there, lol its cos I have been using Xcode for a long while and I’m now using android studio forgot need to edit that file now Many thanks.

You will still need to use the COCOS2D_VERSION define from cocos2d.h to handle differences in your source code (check the post above by @slackmoehrle). The only alternative to this is creating your own version definition in the CMakeLists.txt, and passing that to the compiler.

The main differences between 3.17.2 and 4.0 will be related to the rendering and shader code, such as cocos2d::GLProgramState in 3.17.2 and cocos2d::backend::ProgramState in 4.0.
