Question

我试图在我的Fedora VM上交叉编译Valgrind，以使其在自定义嵌入式Linux设备上运行（使用带有ARM Cortex M4 CPU的Kinetis KL2x MCU运行Yacto）。我有一个正确配置的QT IDE来交叉编译和部署QT项目到设备。我想知道跨越编译非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＆gt; New Project＆gt; Import Project＆gt; Import Existing Project），并且我一直收到此错误：

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。是否可以使用交叉编译器本身编译Valgrind（arm-poky-linux-gnueabi-g ++）？我最好更改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，我使用了多个不同的makefile？）？还是有更好的方法让我失踪？系统没有任何自己的包管理工具或编译器。任何帮助/意见都将非常感激。

使用Yocto工具链交叉编译valgrind的示例如下：

# 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

此处，安装目录为out，您也可以使用${SDKTARGETSYSROOT}/usr安装到--prefix="${SDKTARGETSYSROOT}/usr"

使用Yocto SDK检查this link交叉编译的基本示例

Answer 2

我认为最简单的方法是在你的yocto构建环境中构建它（source poky / oe_init_build_env）并使用

构建valgrind

bitbake -c build valgrind

然后查看构建文件夹tmp / work /＆＃34; plattform＆＃34; / valgrind /＆＃34; version＆＃34; / image / for files

将Valgrind交叉编译并部署到嵌入式Linux设备
