arm - 用于 ARM 的 Valgrind，带有 Linaro 工具链，需要带有 Buildroot 的 libc6-dbg

Question

我在 Ubuntu 10.04 主机上使用以下命令与 Linaro 工具链交叉编译了适用于 ARM 的 Valgrind (http://valgrind.org/downloads/valgrind-3.8.1.tar.bz2)(我使用的是 Buildroot ):

export PATH=$PATH:/home/user/toolchain/linaro/bin
CC=arm-linux-gnueabi-gcc CFLAGS=-I/home/user/toolchain/linaro/arm-linux-gnueabi/libc/usr/include LDFLAGS=-L/home/user/toolchain/linaro/arm-linux-gnueabi/libc/usr/lib ./configure --prefix=/opt/valgrind --host=armv7-none-linux-gnueabi --target=arm-none-linux-gnueabi --build=i386-ubuntu-linux
make
sudo make install

当我将二进制文件复制到 ARM 目标板时，出现以下错误:

我的 Linaro 工具链版本是:

gcc version 4.7.1 20120402 (prerelease) (crosstool-NG linaro-1.13.1-2012.04-20120426 - Linaro GCC 2012.04) 

我在 Google 上进行了搜索，但找不到解决方案。如何让 Valgrind 在我的目标板上工作？我使用 Buildroot 来构建我的系统，但 libc6-dbg 不是我可以在构建系统中找到的包。我需要从工具链 sysroot 复制一些目录或文件吗？谢谢-

我用来运行 Valgrind 的命令如下所示:

# which valgrind
/usr/bin/valgrind
# valgrind /home/user/MyQtApp
==216== Memcheck, a memory error detector
...

Answer 1

那么您正在使用 Buildroot 或 OpenEmbedded 来构建您的 Libc？

如果是 OE，那么您应该在本地存储库 (TMPDIR/deploy/ipk) 中提供 libc6-dbg 软件包。或者将“dbg-pkgs”添加到 IMAGE_FEATURES 中并重建您的镜像。

Glibc 2.12 显示您正在使用旧版本的 OpenEmbedded。但即使这样也应该给你 libc6-dbg 包。

无法帮助使用 Buildroot，因为从未使用过它。
