【问题描述】：
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 中删除所有非标准包含和库来解决（那里碰巧有一个 uuid/uuid.h ...）。尽管如此，它编译了尽管下面描述的错误，/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;
...
我没有回答这个问题，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
为了摆脱关于部署目标的警告，我在编译前编辑了Makefile：
$ cat Makefile
...
126 MACOSX_DEPLOYMENT_TARGET=10.3 # => 10.6
...
原始问题
在尝试从源代码构建 Python 2.6.4 时，我遇到了错误：
$ uname -v
$ Darwin Kernel Version 10.2.0: Tue Nov 3 10:37:10 PST 2009; \

...
$ make
...
...
/usr/include/hfs/hfs_format.h:765: error: \

它似乎植根于Python/mactoolboxglue.c。欢迎提示！
我也收到很多此类警告：
/usr/include/AvailabilityMacros.h:108:14: warning: #warning Building for \
Intel with Mac OS X Deployment Target < 10.4 is invalid.

【问题讨论】：
-
/usr/include/AvailabilityMacros.h:108:14: warning: #warning Building for \ Intel with Mac OS X Deployment Target < 10.4 is invalid.这些错误是由 Python ./configure 脚本将 MACOSX_DEPLOYMENT_TARGET 默认设置为 10.3 引起的。请参阅我的答案以了解如何摆脱这些。 -
在运行
./configure之前执行export MACOSX_DEPLOYMENT_TARGET=10.6而不是编辑 makefile。
