适配龙芯平台的Apache交叉编译
下载Apache源码：
- 从http://www.apache.org/ 上下载apache_1.3.39.tar.gz，然后解压缩的一个目录，然后转到apache_1.3.39目录。
- 我这边下载了httpd-2.4.41…tar.gz的包，解压后：
编译安装
- 执行：./configure
- 【报错】：configure: error: APR not found. Please read the documentation.
- 【解决方法】：缺乏依赖的APR源码包，下载安装：https://apr.apache.org/download.cgi
- 【报错】：checking for APR-util… no
- 【解决方法】：缺乏依赖的APR-UTIL安装包，继续下载安装对应的包。
安装依赖的APR包：
- 下载对应的APR源码包：https://apr.apache.org/download.cgi
- 解压：tar -xvf apr-1.7.0.tar.gz
./configure --prefix=/home/ww/Apache/mips-apr make make install
安装依赖的APR-UTIL包：
tar -xvf apr-util-1.6.1.tar.gz mkdir x86-apr-util ./configure --prefix=/home/ww/Apache/x86-apr-util/ --with-apr=/home/ww/Apache/x86-apr/bin/apr-1-config make make install
安装完成依赖库后继续安装
./configure --with-apr=/home/ww/Apache/x86-apr --with-apr-util=/home/ww/Apache/x86-apr-util
- 显示
make make install
- 此时，完成了x86平台下的源码安装，但是我们需要的是使用龙芯mips编译器编译的龙芯平台下使用的Apache运行环境，所以还需要回到开始的状态继续配置安装。
龙芯平台下的MIPS交叉编译Apache
- 配置：
./configure --with-apr=/home/ww/Apache/x86-apr --with-apr-util=/home/ww/Apache/x86-apr-util --host=mips
- 【报错】

- 应该是没有编译对应平台下的APR、apr-uttil库，使用交叉编译器重新编译对应平台下的APR库及apr-util库。
交叉编译Apr库
cd apr-1.7.0 sudo ./configure --prefix=/home/ww/Apache/mips-apr --host=mips CC=/opt/opt/gcc-4.9.3-64-gnu/bin/mips64el-linux-gcc CXX=/opt/opt/gcc-4.9.3-64-gnu/bin/mips64el-linux-g++ LD=/opt/opt/gcc-4.9.3-64-gnu/bin/mips64el-linux-ld ac_cv_file__dev_zero=yes ac_cv_func_setpgrp_void=yes apr_cv_tcp_nodelay_with_cork=yes --cache=mips64el-linux.cache make
- 【报错】：

修改mips64el-linux.cache中的内容：
apr_cv_process_shared_works=yes apr_cv_mutex_robust_shared=yes ac_cv_sizeof_struct_iovec=8
- 继续configure配置。
- 【报错】：
- 安装apache的依赖apr时报rm: cannot remove ‘libtoolT’: No such file or directory的错
编辑configure
找到RM" RM “RM"cfgfile” 将其注释掉即可
$RM "$cfgfile" 将其注释即可
最后还是没能成功编译完成。
- 不过借助buildroot工具包，成功在这里完成了MIPS龙芯平台下的Apache运行环境的编译。
- 哎。。。。
