我使用以下选项运行configure：
./configure --target=armv5tel CC=arm-linux-gnueabi-gcc --host=i686-linux
然后跑了make
我遇到以下错误：

我错过了什么吗？

解决方法
您的配置参数不适合交叉编译.要使用最近的autoconf进行交叉编译,您只需指定主机并让其完成剩下的工作.所以它会更像这样：
./configure –host = arm-linux-gnueabi
我还必须通过将“armv7 *”替换为“arm *”来修改配置脚本.你会看到哪里.
但是,还有另一个问题. valgrind中的ARM支持涵盖所有ARMv5指令以及v6和v7指令的选择子集.但是,这是一个很大但是,实际上RUN valgrind你必须使用能够运行ARMv7代码的cpu.这意味着Cortex-A或更好.
如果您打算在ARMv5类处理器(如XScale)上运行valgrind,它将无法工作,并且目标程序将因非法操作码而出错.
伤心但真实.对我来说没有valgrind.
HTH.
