qt - 交叉编译和部署 Valgrind 到嵌入式 linux 设备

Question

我正在尝试在我的 Fedora VM 上交叉编译 Valgrind，以便让它在自定义嵌入式 Linux 设备上运行(运行 Yacto 和带有 ARM Cortex M4 CPU 的 Kinetis KL2x MCU)。我有一个正确配置的 QT IDE，可以交叉编译 QT 项目并将其部署到设备。我想知道交叉编译非 QT 应用程序的最佳途径是什么。我尝试使用现有项目(Valgrind 源代码@ http://valgrind.org/downloads/valgrind-3.12.0.tar.bz2)创建一个新项目(在 QT>New Project>Import Project>Import Existing Project 中)，但我不断收到此错误:

17:20:46: Running steps for project valgrind...
17:20:46: Starting: "/usr/bin/make" all
make: *** No rule to make target `all'.  Stop.
17:20:46: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project valgrind (kit: ----)
When executing step "Make"
17:20:46: Elapsed time: 00:00.

我不确定如何解决它。是否可以仅使用交叉编译器本身 (arm-poky-linux-gnueabi-g++) 来编译 Valgrind？我是否最好更改 makefile 以使用交叉编译器而不是 gcc，然后使用 scp 将文件发送到我的设备(如果是这样，我使用许多不同的 makefile 中的哪一个？)？还是有更好的方法让我失踪？该系统本身没有任何包管理工具或编译器。非常感谢任何帮助/输入。

交叉编译环境设置后构建配方时出错:

使用 Yocto 工具链交叉编译 valgrind 的示例是:

# setup workspace
mkdir workspace && cd workspace

# download Yocto sdk
wget http://gumstix-yocto.s3.amazonaws.com/sdk.sh

#Install it to workspace/sdk
./sdk.sh

source sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi

# download valgrind tarball
wget http://valgrind.org/downloads/valgrind-3.12.0.tar.bz2

# extract source
tar jxf valgrind-3.12.0.tar.bz2 && cd valgrind-3.12.0

# this fix issue with unknown arm architecture (see http://stackoverflow.com/questions/29514706/cross-compiling-valgrind-for-arm)
sed -i -e "s#armv7#arm#g" configure

./configure --host=arm-poky-linux-gnueabi --prefix="$(pwd)/out"

make -j16

make install

这里的安装目录是out，也可以通过--prefix="${SDKTARGETSYSROOT}/安装到${SDKTARGETSYSROOT}/usr usr”
