最近工作中要编译一个第三方的C库用于iOS端使用,我直接在Mac OS的终端中./configure & make & make install常规走下来,却无法在真机iOS上使用,提示“Symbol(s) not found for architecture arm64”! 通过命令file *.a或者lipo -info *.a,可以看到生成的静态库文件时x86_64架构的. 编译器粗略分为词法分析,语法分析,类型检查,中间代码生成,代码优化,目标代码生成,目标代码优化.把中间代码生成
1.交叉编译 # tar -xvf sudo-1.8.6p7.tar.gz # cd sudo-1.8.6p7/ # mkdir build # ./configure --prefix=/home//sudo-1.8.6p7/build/ CC=aarch64-linux-gnu-gcc AR=aarch64-linux-gnu-ar --host=aarch64-linux-gnu # make & make install # ls build/ bin include libexec s
