Mac OS 10.6 / Snow Leopard上的Python构建问题

我在Snow Leopard上遇到了Python 2.6.4的构建问题.

> Mac OS X 10.6
> Yonah CPU,32位
> gcc-4.2.1

更新我

通过从CFLAGS中删除所有非标准的include和库来解决(碰巧那里是一个uuid / uuid.h …).尽管如此,尽管有以下描述的错误,它还是进行了编译,其中/usr/include/hfs/hfs_format.h:765是一个热点.对于好奇的还是机智的,有问题的源文件：

$cat /usr/include/hfs/hfs_format.h
...
748 #include <uuid/uuid.h>
749 
750 /* JournalInfoBlock - Structure that describes where our journal lives */
751 
752 // the original size of the reserved field in the JournalInfoBlock was
753 // 32*sizeof(u_int32_t).  To keep the total size of the structure the 
754 // same we subtract the size of new fields (currently: ext_jnl_uuid and
755 // machine_uuid).  If you add additional fields, place them before the
756 // reserved field and subtract their size in this macro.
757 //
758 #define JIB_RESERVED_SIZE  ((32*sizeof(u_int32_t)) - sizeof(uuid_string_t) - 48)
759 
760 struct JournalInfoBlock {
761         u_int32_t       flags;
762         u_int32_t       device_signature[8]; // signature used to locate device.
763         u_int64_t       offset;        // byte offset to the journal on the device
764         u_int64_t       size;          // size in bytes of the journal
765         uuid_string_t   ext_jnl_uuid;
766         char            machine_serial_num[48];
767         char            reserved[JIB_RESERVED_SIZE];
768 } __attribute__((aligned(2), packed));
769 typedef struct JournalInfoBlock JournalInfoBlock;
...

我将问题悬而未决,因为构建产生了太多警告,并且此错误仍然让我感到困惑…

更新二

为了摆脱有关部署目标的警告,我在编译之前编辑了Makefile：

$cat Makefile
...
126 MACOSX_DEPLOYMENT_TARGET=10.3 # => 10.6
...

原始问题

尝试从源代码构建Python 2.6.4时,出现错误：

$uname -v
$Darwin Kernel Version 10.2.0: Tue Nov  3 10:37:10 PST 2009; \
    root:xnu-1486.2.11~1/RELEASE_I386

$cd ~/src/Python-2.6.4
$./configure --enable-universalsdk=/ --prefix=$HOME
checking for --with-universal-archs... 32-bit
...
checking machine type as reported by uname -m... i386
...
checking for OSX 10.5 SDK or later... no   // <- But I have XCode + the SDKs installed?
...

$make
...

...
/usr/include/hfs/hfs_format.h:765: error: \
    expected specifier-qualifier-list before ‘uuid_string_t’

它似乎扎根于Python / mactoolboxglue.c.提示欢迎！

我也收到很多这类警告：

/usr/include/AvailabilityMacros.h:108:14: warning: #warning Building for \
Intel with Mac OS X Deployment Target < 10.4 is invalid.
gcc -c -arch ppc -arch i386 -isysroot /  -fno-strict-aliasing -DNDEBUG -g \

             from Include/Python.h:58,
             from Objects/structseq.c:4:

解决方法:

尝试在配置参数中添加–universal-archs = 32位.

编辑：您可能还需要设置环境变量MACOSX_DEPLOYMENT_TARGET = 10.6并显式使用10.6 SDK：

export MACOSX_DEPLOYMENT_TARGET=10.6
./configure --universal-archs=32-bit --enable-universalsdk=/Developer/SDKs/MacOSX10.6.sdk ...

在10.6上构建Python仍然存在一些配置问题.如果重新使用构建目录,请确保清除了先前运行configure可能遗留下来的所有缓存文件.

顺便说一句,如果您只需要32位版本,则可以使用python.org版本的2.6.4 OS X安装程序.
