ARMv5tel 的 Valgrind 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

然后运行 ​​make

我遇到以下错误：

我错过了什么吗？

Answer 1

您的配置参数不适合交叉编译。要与最近的 autoconf 进行交叉编译，您只需指定主机并让它计算其余部分。所以它更像是这样的：

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

我还必须通过用“arm*”替换“armv7*”来修改配置脚本。你会看到在哪里。

然而，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，这是一个很大的但是，要实际运行 valgrind，您必须使用能够运行 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，并且目标程序将出现非法操作码错误。

悲伤但真实。对我来说没有valgrind。

HTH。

1. make clean
2. ./configure CC="你的gcc路径" --target=arm-none-linux-gnueabi --host=armv7-none-linux-gnueabi
3. make
4. sudo make install
