i.MX交叉编译openssl

freescale的i.MX采用了yocto的框架编译。提取toolchain并安装后，在toolchain的安装目录有一个脚本可以用来设置交叉编译的环境变量。 ISSUE 但是当使用此环境变量编译openssl后，会出现以下问题： [crayon-6a14916f8381a941312126/] FIXes 此时可以通过手动配置编译环境解决： 重新开一个shell 设置交叉编译器目录到PATH [crayon-6a14916f8381f914688691/] 采用通用32位配置Autoconf [crayon-6a14916f83820357347092/] 修改Makefile中的CC为交叉编译器的GCC，注意不要忘了后面的参数 [crayon-6a14916f83821040144471/] 编译 [crayon-6a14916f83822841139092/] 参考 http://berniechenopenvpn.blogspot.com/2015/10/wpasupplicant-am335x.html
