Mac OS 10.6/Snow Leopard 上的 Python 构建问题

Question

我在 Snow Leopard 上遇到 Python 2.6.4 的构建问题。

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

更新一

通过从 CFLAGS 中删除所有非标准包含和库来解决(那里碰巧有一个 uuid/uuid.h ...)。尽管如此，尽管下面描述的错误，它还是编译了，/usr/include/hfs/hfs_format.h:765 是一个热点。对于好奇或足智多谋的人，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;
...

我不问这个问题，因为构建产生了太多的警告和这个错误，仍然让我有点困惑......

更新二

为了消除有关部署目标的警告，我在编译前编辑了 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 时遇到错误:

$ 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 Root 于 Python/mactoolboxglue.c。欢迎提示!

我也收到了很多这样的警告:

Answer 1

尝试将 --universal-archs=32-bit 添加到 configure 参数。

编辑:您可能还需要设置环境变量 MACOSX_DEPLOYMENT_TARGET=10.6 并明确使用 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。如果您重新使用构建目录，请确保清除之前运行 configure 可能留下的所有缓存文件。

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