因为一直用Ubuntu 20.04环境，没有使用官方的VMWARE镜像搭建环境，所以直接开贴来一篇。 一、开发环境准备

（一）操作系统

使用的是Ubuntu 20.04。

复制root@EliteDesk:/$ uname -a Linux EliteDesk 5.15.0–48-generic #54~20.04.1-Ubuntu SMP Thu Sep 1 16:17:26 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

（二）Cmake

执行复制sudo apt install cmake命令安装cmake。

复制root@EliteDesk:/$ sudo apt install cmake [sudo] password for root: Reading package lists… Done Building dependency tree Reading state information… Done The following package was automatically installed and is no longer required: libfwupdplugin1 Use sudo apt autoremove to remove it. The following additional packages will be installed: cmake-data libjsoncpp1 librhash0 Suggested packages: cmake-doc ninja-build The following NEW packages will be installed: cmake cmake-data libjsoncpp1 librhash0 0 upgraded, 4 newly installed, 0 to remove and 0 not upgraded.

二、安装交叉编译工具链

直接使用官方下载的rv1126_rv1109_compiler_20220715_175105.tar.gz 文件，执行复制sudo tar xvf rv1126_rv1109_compiler_20220715_175105.tar.gz -C /

千万记得加上sudo，不要问为什么。 复制root@EliteDesk:/$ sudo tar xvf rv1126_rv1109_compiler_20220715_175105.tar.gz -C / [sudo] password for root: opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/cc1plus opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/collect2 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/liblto_plugin.so.0.0.0 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/install-tools/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/install-tools/mkinstalldirs opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/install-tools/fixincl opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/install-tools/mkheaders opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/install-tools/fixinc.sh opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/f951 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/plugin/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/plugin/gengtype opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/lto-wrapper opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/liblto_plugin.so opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/liblto_plugin.so.0 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/lto1 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/libexec/gcc/arm-linux-gnueabihf/8.3.0/cc1 opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/8.3–2019.03-x86_64-arm-linux-gnueabihf-manifest.txt opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/share/ opt/rv1126_rv1109_sdk/prebuilts/gcc/linux-x86/arm/gcc-arm-8.3–2019.03-x86_64-arm-linux-gnueabihf/share/locale/

然后坐等安装完成。

设置环境变量，将刚才安装的SDK包含：

复制root@EliteDesk:/media/rv1126$ export PATH=/opt/rv1126_rv1109_sdk/buildroot/output/rockchip_face_board/host/bin:$PATH root@EliteDesk:/media/rv1126$ export ARCH=arm root@EliteDesk:/media/rv1126$ export CROSS_COMPILE=arm-linux-gnueabihf-

测试交叉编译环境是否安装成功：

复制root@EliteDesk:/media/rv1126$ qmake -v QMake version 3.1 Using Qt version 5.15.2 in /opt/rv1126_rv1109_sdk/buildroot/output/rockchip_face_board/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib root@EliteDesk:/media/rv1126$ arm-linux-gnueabihf-gcc -v Using built-in specs.

OK，一切正常。

三、HELLO Easy EAI

来个hello小程序吧。

复制#include #include int main(void) { int i; for(i = 0; i < 5; i++) { printf(“hello Easy EAI!%d n”, i); } return 0; }

这样就好，之后执行复制arm-linux-gnueabihf-gcc hello.c -o hello，生成ARM的可执行程序hello，再通过复制adb push hello /userdata到开发板。

复制adb shell登录到开发板，执行程序，执行之前记得chmod修改下属性。
