如何为 64 位平台编译 32 位 apache 模块? [英] How do I compile a 32 bit apache module for a 64 bit platform?
问题描述
我正在尝试在 mac os x 10.5.7 上为 apache 完成 mod_auth_kerb.我没有收到编译错误，但是当 apache 尝试加载它时:
I am trying to comple mod_auth_kerb for apache on mac os x 10.5.7. I get no compilation errors, but when apache tries to load it:
org.apache.httpd[95092]:httpd:/private/etc/apache2/httpd.conf 第 160 行的语法错误:无法将/usr/libexec/apache2/mod_auth_kerb.so 加载到服务器:dlopen(/usr/libexec/apache2/mod_auth_kerb.so, 10): 找不到合适的图像.确实找到了: /usr/libexec/apache2/mod_auth_kerb.so:mach-o，但架构错误
org.apache.httpd[95092]: httpd: Syntax error on line 160 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec/apache2/mod_auth_kerb.so into server: dlopen(/usr/libexec/apache2/mod_auth_kerb.so, 10): no suitable image found. Did find: /usr/libexec/apache2/mod_auth_kerb.so: mach-o, but wrong architecture
我在 make 文件中尝试了以下内容:
I have tried the following in the make file:
ARCHFLAGS='-arch ppc64'CPPFLAGS = -I.-Ispnegokrb5 $(KRB5_CPPFLAGS) $(KRB4_CPPFLAGS) $(DEFS) -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64LDFLAGS = $(KRB5_LDFLAGS) $(KRB4_LDFLAGS) $(LIB_resolv) -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64CFLAGS = -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64
ARCHFLAGS='-arch ppc64' CPPFLAGS = -I. -Ispnegokrb5 $(KRB5_CPPFLAGS) $(KRB4_CPPFLAGS) $(DEFS) -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64 LDFLAGS = $(KRB5_LDFLAGS) $(KRB4_LDFLAGS) $(LIB_resolv) -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64 CFLAGS = -mpowerpc64 -mcpu=G5 -mtune=G5 -arch ppc64
我查看了这些主题:

http://objectmix.com/apache/690208-re-mod_auth_kerb-mac-os-x-10-5-client.html
我也在源代码中更改了这一点:
I also changed this in the source:
来自krb5_rc_resolve_full
到__KerberosInternal_krb5_rc_resolve_full
from
krb5_rc_resolve_full
to
__KerberosInternal_krb5_rc_resolve_full
我无法让 apache 加载它，它声称它是错误的架构.我认为 apache 在这个版本的 mac 服务器中是 64 位的，所以这可能是问题所在.我只是不知道如何度过它.
I cannot get apache to load it and it claims it is the wrong architecture. I think apache is 64 bit from the ground up in this version of mac server so that is probably the problem. I just don't know how to get through it.
第 160 行是 httpd.conf 文件中的一条红鲱鱼(它有 ##).
Line 160 is a red herring in the httpd.conf file (it has ##).
我不知道如何正确编译它，希望得到帮助.
I don't know how to compile it correctly and was hoping for help.
我有一个 G5 PPC 64.
I have a G5 PPC 64.
谢谢.
奇怪的是:
otool -hv mod_auth_kerb.so mod_auth_kerb.so:马赫头魔术 cputype cpusubtype caps filetype ncmds sizeofcmds flags
otool -hv mod_auth_kerb.so mod_auth_kerb.so: Mach header magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC_64 PPC64 ALL 0x00 BUNDLE 10 1328 NOUNDEFS DYLDLINK TWOLEVEL
MH_MAGIC_64 PPC64 ALL 0x00 BUNDLE 10 1328 NOUNDEFS DYLDLINK TWOLEVEL
所以我不知道出了什么问题.
So I don't know what's wrong.
我使用的是 PPC64，这就是我编译的样子.
I am on the PPC64 and that's what it looks like I have compiled.
推荐答案
如果我正确地回答了这个问题，我认为您将需要构建/安装一个交叉编译工具链 将其构建为从 PPC 到 x86_64 或其他非 PPC 架构，甚至在某些情况下，PPC 到 PPC64，反之亦然.
If i'm following the question correctly, I think you will need to build/install a cross compiling toolchain to build it from PPC to x86_64 or another non-PPC architecture, or even in some cases, PPC to PPC64 and vice-versa.
如果您不熟悉 GCC、Unix 工具链和达尔文基金会的一般内容，我不会建议您这样做.
I would not advise this if you are unfamiliar with GCC, the Unix toolchain and the Darwin foundation stuff in general.
您或许可以在网络上找到 Darwin 工具链设置.一些正确方向的链接:
You might be able to find Darwin toolchain setups on the web. Some links in the right direction:
