Objective c OSX弃用警告CMake

我正在使用

CMake

构建一些代码，这些代码应该根据

ScriptingBridge

进行编译

我看到数以万计的日志行，例如：

正在使用以下工具编译这些文件：

/usr/bin/c++    -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/include -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/../libwatchedit/include    -x objective-c -o CMakeFiles/whatsplaying.dir/src/osx/itunes_scripting_bridge.m.o -c /Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/src/osx/itunes_scripting_bridge.m

/usr/bin/gcc -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/include -I/Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/../libwatchedit/include    -F/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks  -x objective-c -o CMakeFiles/whatsplaying.dir/src/osx/itunes_scripting_bridge.m.o -c /Users/codebeaker/Projects/watchedit-client-code/src/libwhatsplaying/src/osx/itunes_scripting_bridge.m

在我的Mac上查看了（Clang）

gcc

的手册页后，有一个听起来很有趣：

-Fdir Add the framework directory dir to the head of the list of directories to be searched for header files. These directories are interleaved with those specified by -I options and are scanned in a left-to-right order. A framework directory is a directory with frameworks in it. A framework is a directory with a "Headers" and/or "PrivateHeaders" directory contained directly in it that ends in ".framework". The name of a framework is the name of this directory excluding the ".framework". Headers associated with the framework are found in one of those two directories, with "Headers" being searched first. A subframework is a framework directory that is in a framework's "Frameworks" directory. Includes of subframework headers can only appear in a header of a framework that contains the subframework, or in a sibling subframework header. Two subframeworks are siblings if they occur in the same framework. A subframework should not have the same name as a framework, a warning will be issued if this is violated. Currently a subframework cannot have subframeworks, in the future, the mechanism may be extended to support this. The standard frameworks can be found in "/System/Library/Frameworks" and "/Library/Frameworks". An example include looks like "#include ", where Framework denotes the name of the framework and header.h is found in the "PrivateHeaders" or "Headers" directory. -iframeworkdir Like -F except the directory is a treated as a system directory. The main effect is to not warn about constructs contained within header files found via dir. -Fdir 将框架目录dir添加到要搜索头文件的目录列表的头部。这些目录与那些目录交错 由-I选项指定，并按从左到右的顺序扫描。 框架目录是包含框架的目录。框架是包含“Headers”和/或“PrivateHeaders”目录的目录 直接在以“.framework”结尾的it中。框架名称是此目录的名称，不包括“.framework”。与关联的标题 该框架位于这两个目录之一，首先搜索“Headers”。子框架是位于 框架的“框架”目录。子框架标题的包含只能出现在包含子框架的框架的标题中，或在 同级子框架标头。如果两个子框架出现在同一框架中，则它们是同级。子框架不应与子框架具有相同的名称 框架中，如果违反此规则，将发出警告。当前子框架不能有子框架，将来可能会 扩展到支持这一点。标准框架可在“/System/Library/frameworks”和“/Library/frameworks”中找到。一个例子包括外观 与“#include”类似，其中Framework表示框架和头的名称。h可在“PrivateHeaders”或“Headers”中找到 目录 -iframeworkdir 与-F类似，只是目录被视为系统目录。其主要作用是不警告所找到的头文件中包含的构造 经由目录。 也许我应该找

-iframework

。在终端上使用

-iframework

构建时，手动完成此操作，不会出现任何弃用警告

但是，CMake不支持使用

-framework

的选项。从他们的

find_library（）

文档中：

CMake将使用a-frameworkA和a-F将框架链接到目标

---

我正在寻找一种安静的方式。我还有来自OpenSSL'x EVA接口的（4倍）较小的警告，我可以处理这些警告。。。提前感谢。

答案是使用

-iframework

，这可能是为了在无法解决系统级弃用警告时忽略它们

相反，我能够使用

-Wno不推荐的声明

，这是一个指向

GCC

的标志，它被记录在案并且随处可见。它是可靠的，我将其包括在我的CMake声明中：

IF(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
  find_and_add_framework(Foundation watchedit)
  find_and_add_framework(Cocoa watchedit)
  find_and_add_framework(AppKit watchedit)
  find_and_add_framework(ScriptingBridge watchedit)
  set_source_files_properties(${sources} PROPERTIES COMPILE_FLAGS
    "-xobjective-c -Wno-deprecated-declarations")
  set_source_files_properties(${sources} PROPERTIES LANGUAGE C)
ENDIF(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")

对于任何想从中受益的人，下面是

find\u和\u add\u框架

的实现。我不确定是从哪里抄袭的，但这不是我自己的作品：

macro(FIND_AND_ADD_FRAMEWORK fwname appname)
    find_library(FRAMEWORK_${fwname}
        NAMES ${fwname}
        PATHS ${CMAKE_OSX_SYSROOT}/System/Library
        PATH_SUFFIXES Frameworks
        NO_DEFAULT_PATH)
    if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
        MESSAGE(ERROR ": Framework ${fwname} not found")
    else()
        TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})
        # MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
    endif()
endmacro(FIND_AND_ADD_FRAMEWORK)
