arm 32位板的Valgrind交叉编译-橙色pi

如何在x86 ubuntu机器上交叉编译ARM的valgrind

---

这里是一个自包含的过程，假设您是在x86_64 Ubuntu Linux机器上构建的。如果不是这样，只需为linux发行版提供的

arm none linux gnueabihf

目标安装交叉编译器，确保它位于您的路径中，并相应地修改

configure

命令

在PC端：

# downloading/installing toolchain
wget https://developer.arm.com/-/media/Files/downloads/gnu-a/10.2-2020.11/binrel/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf.tar.xz?revision=d0b90559-3960-4e4b-9297-7ddbc3e52783&la=en&hash=985078B758BC782BC338DB947347107FBCF8EF6B

sudo mkdir -p /opt/arm/10
sudo tar Jxf gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf.tar.xz -C /opt/arm/10

# downloading/extracting valgrind
wget https://sourceware.org/pub/valgrind/valgrind-3.16.1.tar.bz2
tar jxf valgrind-3.16.1.tar.bz2

# building
export PATH=/opt/arm/10/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf/bin:$PATH
mdkir valgrind
cd valgrind

../valgrind-3.16.1/configure --host=arm-none-linux-gnueabihf --prefix=$(pwd)/valgrind-3.16.1-arm-none-linux-gnueabihf
make all install

关于Orangepi：

将

valgrind-3.16.1-arm-none-linux-gnueabihf

目录及其子目录的内容从PC复制到Orangepi的/usr/local目录中

安装

libc6dbg

（假设您在Orangepi上运行Ubuntu或Debian）：

apt get Install libc6dbg

使用以下程序进行测试：
