问题描述
在msys2上进行的httpd构建失败，并出现以下错误:
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory
在实际的Linux发行版上，安装expat-devel软件包似乎可以解决问题请参阅在这里，更确切地说，expat-devel是apr-util的先决条件至少在msys2上缺少其标头.
那么由于没有可用的expat-devel软件包或头文件，因此如何使用msys构建httpd?在配置httpd --with-included-apr时，apr-utils在哪里寻找expat标头或如何配置它?
更准确地 CHANGES-APR-UTIL-1.6 文档说
应该在httpds构建目录树中的哪些位置安装expat标头和库?
我最终不得不分别构建expat，然后出现了其他错误并找到了解决方案，这要归功于此链接，用于缺少libtool，并链接到那链接，可以有效地在不生成导出重新定义的情况下构建外派人员.
在此处找到完整的构建脚本:

构建过程成功完成，但很有用，因为httpd无法按照此处所述进行加载，因此无法使用运行时是很有用的/p>
httpd build on msys2 fails with the following error:
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory
On real linux distros, installing the expat-devel package seems to solve the problem see here,more precisely, expat-devel is an apr-util prerequisiteand at least its headers ar missing on msys2.
So how to build httpd with msys since no expat-devel package or headers is available ?When configuring httpd --with-included-apr, where do apr-utils look for expat headers or how to configure that ?
more precisely the CHANGES-APR-UTIL-1.6 documentation says
where should expat headers and libs be installed in httpds build directory tree ?
I finally had to build expat separately,then other errors arised and found a solution thanks tothis link for missing libtool and to that link for the effective way to build expat without generating export redefinition.
let find the full build script here:

The build process completed successfully,but usefull to say that the runtime can't be used since httpd is not able to load its dynamic modules as described here
