c++macos cmake cocos2d-x

After upgrade to macOS Big Sur 11.01 i get the following error:

clang: error: no such file or directory: '/usr/lib/libz.dylib' clang: error: no such file or directory: '/usr/lib/libiconv.dylib' Command Ld failed with a nonzero exit code

How to reproduce: make new cocos2d-x project using:

cocos -n -d dirname -l cpp
cd dirname/MyCppGame
mkdir build-iphone
cd build-iphone
cmake .. -GXcode -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos

Open the generated xcode project (change bundle identifier) and build

Versions:

macOS Big sur 11.01
CMake 3.18 or CMake 3.19.0-rc3
cocos2d-x v4.0
Xcode 12.2

What solution did you use finally? – Incognito 25/6, 2021 at 4:3

I still use the first answer because i use cmake to build the apps (cmake is doing the same). If you only have one or two project you can use the other answers. – Streamer 26/6, 2021 at 14:58

Setting libz each time is tedious, did you find a solution using CMake ? – Incognito 19/4, 2022 at 4:27

I changed the file: 'CocosConfigDepend.cmake' in cmake/modules/ of the cocos2d-x v4.0 library.

    elseif(IOS)
        # Locate system libraries on iOS
        find_library(UIKIT_LIBRARY UIKit)
        find_library(OPENGLES_LIBRARY OpenGLES)
        find_library(CORE_MOTION_LIBRARY CoreMotion)
        find_library(AVKIT_LIBRARY AVKit)
        find_library(CORE_MEDIA_LIBRARY CoreMedia)
        find_library(CORE_TEXT_LIBRARY CoreText)
        find_library(SECURITY_LIBRARY Security)
        find_library(CORE_GRAPHICS_LIBRARY CoreGraphics)
        find_library(AV_FOUNDATION_LIBRARY AVFoundation)
        find_library(WEBKIT_LIBRARY WebKit)
   
        find_library(ZLIB z)
        find_library(ICONVLIB iconv)

        list(APPEND PLATFORM_SPECIFIC_LIBS
             ${UIKIT_LIBRARY}
             ${OPENGLES_LIBRARY}
             ${CORE_MOTION_LIBRARY}
             ${AVKIT_LIBRARY}
             ${CORE_MEDIA_LIBRARY}
             ${CORE_TEXT_LIBRARY}
             ${SECURITY_LIBRARY}
             ${CORE_GRAPHICS_LIBRARY}
             ${AV_FOUNDATION_LIBRARY}
             ${WEBKIT_LIBRARY}
             ${COCOS_APPLE_LIBS}
             ${ZLIB}
             ${ICONVLIB}
             #"/usr/lib/libz.dylib"
             #"/usr/lib/libiconv.dylib"
             )
    endif()

Added the ZLIB and ICONVLIB, and removed full path rows.

This is more like a hack. We need a proper solution to this problem. Have you tried installing the libraries using a package manager like Homebrew? Here are the links: formulae.brew.sh/formula/libiconv and formulae.brew.sh/formula/zlib – Corpulence 22/11, 2020 at 14:3

This doesn't seem to work by itself. Was there anything else you edited ? I get a bunch of errors when I try this.... – Incognito 19/4, 2022 at 5:0

Here is what I did, instead of ${ZLIB}, I just did -lz, and instead of ${ICONVLIB} did -liconv – Incognito 19/4, 2022 at 5:14

you can fix this issue like this.
