ubuntu64位交叉编译flex为32位程序

首先尝试交叉编译，查看./configure-h后，使用./configure --HOST=i386 编译![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2dvZnJlc2htYW4_size_16_color_FFFFFF_t_70]  
通过以上可看出编译仍为64位。  
查阅博客，得知需首先安装安装依赖包m4、autoconf、automake、libtool和gettext，下载解压后尝试运行./autogen.sh 报出如下错误：

autoreconf: failed to run autopoint: No such file or directory
    autoreconf: autopoint is needed because this package uses Gettext

可知此时本机已含有上述四个依赖，但是缺少**autopoint**,安装此依赖：

sudo apt-get install autopoint

再次运行./autogen.sh ，无错误，尝试编译，此时本机含有的交叉编译工具链为i586，如下：

./configure --host=i586-linux-gcc
    
    checking build system type... x86_64-pc-linux-gnu
    checking host system type... Invalid configuration `i586-linux-gcc': system `gcc' not recognized
    configure: error: /bin/bash build-aux/config.sub i586-linux-gcc failed

如上报出找不到编译工具链，再次添加CC参数，尝试如下：

sudo ./configure --host=i586-linux-gcc CC=i586-linux-gcc

错误与上一致

checking build system type... x86_64-pc-linux-gnu
    checking host system type... Invalid configuration `i586-linux-gcc': system `gcc' not recognized
    configure: error: /bin/bash build-aux/config.sub i586-linux-gcc failed

怀疑没有找到对应编译器导致，将CC参数添加绝对路径尝试成功

sudo ./configure --host=i586-linux CC=/home/ubuntu/.../.../..../.../.../.../../bin/i586-linux-gcc

checking that generated files are newer than configure... done
    configure: creating ./config.status
    config.status: creating Makefile
    config.status: creating doc/Makefile

接下来的make与make install 均成功执行
