z/OS USS 上的 zlib
我正在尝试在 z/OS USS（这就是大型机）上编译 z/lib。 我有 gmake 和 c89 编译器（我假设它符合 c89 标准），并且 USS 应该符合 POSIX。
zlib 似乎会遇到
struct internal_state FAR *state; /* not visible by applications */
以下错误，
c89 -O3 -DUSE_MMAP -D_XOPEN_SOURCE_EXTENDED=1 -D_POSIX_SOURCE -c -o example.o example.c

gmake: *** [example.o] Error 3
但是当我逐渐取出 FAR * （我认为它是一个远指针，但我真的不太确定）时， 错误就会消失。 但由于这是一个库，我不确定删除它会产生什么其他工件。
有人有什么想法吗？
那里有旧的主机头吗？
Im trying to compile z/lib on z/OS USS(thats right a mainframe). ive got gmake and the c89 compiler (which im assuming is c89 standards compliant) and USS is supposed to be POSIX compliant.
But zlib seems to be tripping up on
struct internal_state FAR *state; /* not visible by applications */
with the following error(s)
c89 -O3 -DUSE_MMAP -D_XOPEN_SOURCE_EXTENDED=1 -D_POSIX_SOURCE -c -o example.o example.c

when i progressively take out the FAR * (i think its a far pointer but im really not that sure) the errors go away. But as this is a library, im not sure what other artifacts are going to be produced by removing this.
has anybody got any ideas?
any old mainframe heads out there?

事实证明，zlib 的早期版本可以在 USS 上编译，版本 1.1.4 或接近该版本。 它是一个后级，但我认为这是可行的，因为它是在最新代码中实现 FAR 指针之前。 所以我想我已经可以使用自动取款机了。
感谢你的帮助。
问候
马克。
it turns out there is a previous version of zlib that compiles on USS, version 1.1.4 or close to that. Its a back level, but i presume this works because it is before the implementation of the FAR pointer in the latest code. So atm i think ive got it to work.
thanks for all your help.
Regards
Mark.
FAR 不是 C89 关键字，它是 Microsoft/Intelism，并且可能在某处 #define。 如果不是，您需要将其定义为空：
但是，这可能只能解决许多问题之一。 我猜想该库使用某种形式的条件编译来处理 FAR 指针之类的事情 - 您需要阅读文档以查找哪种配置最适合您的平台。
FAR is not a C89 keyword, it is a Microsoft/Intelism and is probably #defined somewhere. If not, you need to define it as nothing:
However, this will probably only fix one of many problems. I would guess that the library uses some form of conditional compilation to handle things like FAR pointers - you need to read the docs to find which configuration is most suitabkle for your platform.
我会使用 xlc 而不是 c89，因为 xlc 是您的系统默认编译器，但您仍然可能会遇到问题。 我会订阅 MVS-OE 电子邮件列表，上面的人非常有帮助。 有关该列表的信息的链接现在似乎已关闭，因此请发送电子邮件至

I'd use xlc instead of c89 since xlc is your system default compiler but you'll still probably have issues. I'd subscribe to the MVS-OE email list, the people on it are quite helpful. The link to info about the list appears to be down now so send email to

FWIW，IBM 提供了 zlib 的预构建版本，其中包括对最新老式大型机上可用的压缩硬件（所谓的 zEDC）的支持。 请参阅 zEnterprise 的 zlib数据压缩
FWIW, IBM provides a prebuilt version of zlib that includes support for the compression hardware (so-called zEDC) available on recent-vintage mainframes. See zlib for zEnterprise Data Compression
