Valgrind用于ARMv5tel的交叉编译

Question

我使用以下选项运行配置:

./configure --target=armv5tel CC=arm-linux-gnueabi-gcc --host=i686-linux

然后跑

我遇到以下错误:

我想念什么吗？

您的configure参数不适合交叉编译。要使用最新的autoconf进行交叉编译，您只需指定host，然后将剩下的内容搞清楚即可。因此，它将更像这样:

./configure --host = arm-linux-gnueabi

我还必须通过将“armv7 *”替换为“arm *”来修改配置脚本。您会在哪里看到。

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指令的选定子集。但是，这很大，但是要真正运行valgrind，必须使用能够运行ARMv7代码的CPU。那意味着Cortex-A或更好。

如果您打算在ARMv5类处理器(如XScale)上运行valgrind，则它将无法运行，并且目标程序将因非法操作码而出错。

悲伤但真实。没有valgrind对我来说。

HTH。
