在mac OSX 10.8上编译C库以与python包装器一起使用

因此，我是过去几个月一直在学习python的noob。我最近发现了一个名为的python库，并想用它来做一些有趣的WiiMote。由于该库只是C库的一个包装器，我发现我必须先安装这两个库，然后才能开始任何操作

我有一个运行mac的mountain lion，我在编译和安装Wiuse库时遇到了一些严重的问题。自述文件说使用cmake为源代码生成一个MakeFile。在安装cmake、xcode和xcode命令行工具后，我运行了以下命令

cd /build_directory
cmake /source_directory
make
make install

cmake成功地创建了一个MakeFile，gnu make软件构建并安装了一个静态库libwiuse.a和头文件wiiuse.h。静态库安装到/usr/local/lib，头文件安装到/usr/local/include

我不知道如何处理stative图书馆。自述文件让我相信我会得到一个libwiuse.so形式的链接库。我读过静态库，了解到它们只是编译代码的存档。我将.o文件从归档文件提取到一个名为libwiuse的文件夹中，并运行以下代码：

gcc -shared -o libwiiuse.so io.o os_mac_find.o classic.o ir.o os_mac_interface.o dynamics.o motion_plus.o util.o events.o nunchuk.o wiiboard.o guitar_hero_3.o os_mac.o wiiuse.o

我试图编译所有的.oobject？将文件合并到一个.soshared对象中？文件我得到的结果出乎意料

所以我被困在这里了。我不确定对象文件是否是针对X86 64体系结构构建的，因此我对所有文件运行file命令，并对每个文件都得到相同的结果

Mach-O 64-bit object x86_64

我知道我想做什么，这可能真的很容易，但我一直在这里挣扎。有人能帮我吗？

当链接静态wiiuse时。Mac上的库，你还需要链接一些Apple框架。尝试将以下内容添加到CMakeLists.txt：

set(PLATFORM_LIBS)
if(APPLE)
    find_library(IOBLUETOOTH_FRAMEWORK
        NAMES
        IOBluetooth)
    find_library(COREFOUNDATION_FRAMEWORK
        NAMES
        CoreFoundation)
    find_library(FOUNDATION_FRAMEWORK
        NAMES
        Foundation)
    list(APPEND PLATFORM_LIBS
        ${IOBLUETOOTH_FRAMEWORK}
        ${COREFOUNDATION_FRAMEWORK}
        ${FOUNDATION_FRAMEWORK})
endif(APPLE)

然后，在创建目标之后，cmake link命令看起来像

target_link_libraries(${target}
    ${WIIUSE_LIB}
    ${PLATFORM_LIBS})

我原以为静态库会帮我们解决这个问题，但我错了。

虽然这直接涉及到编程工具，但我认为错误来自安装C库的事实值得在superuser上发布。
