Background
This article will introduce something related to rockchip rk3399 cross compilation. Later I will add some testing examples.
System Environment
HostUbuntu 16.04- x86_x64
-
gcc 5.4.0
Targetrk3399- ARM 64 (aarch64)
-
gcc 6.3.1
- Toolchain
- aarch64-linux-gnu-gcc
- aarch64-linux-gnu-g++
Steps
Download the cross compilation tools
- goto https://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/aarch64-linux-gnu/
- download
gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz - cp
gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz/opt (root) - cd /opt
- tar -zxvf gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz
- mv gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu gcc-aarch64-linux-gnu
- edit
~/.bashrc(user)
export PATH=$PATH:/opt/gcc-aarch64-linux-gnu/bin
- source
~/.bashrc - check setup,
aarch64-linux-gnu-gcc -v
Boost 1.66.0
- wget https://dl.bintray.com/boostorg/release/1.66.0/source/boost_1_66_0.tar.gz
- tar -zxvf boost_1_66_0.tar.gz
- cd boost_1_66_0
- ./bootstrap.sh –prefix=$PWD/../boost-1-66-0
- Moidfy project-config.jam to
using gcc : arm : aarch64-linux-gnu-gcc ;
- ./bjam
- ./bjam install
Protobuf 3.5.1
- wget https://github.com/protocolbuffers/protobuf/releases/download/v3.5.1/protobuf-cpp-3.5.1.tar.gz
- tar -zxvf protobuf-cpp-3.5.1.tar.gz
- cd protobuf-3.5.1
- sudo yum install autoconf automake libtool
- ./autogen.sh
generate protoc
- ./configure
- make
- sudo make install
- make disclean
cross compilation
- set configure as below
./configure --build=i686-pc-linux \
--host=aarch64-linux-gnu \
--with-protoc=protoc \
CC=aarch64-linux-gnu-gcc \
CXX=aarch64-linux-gnu-g++ \
--prefix=$PWD/install
- make -j8
- make install
OpenCV 3.4.4
- wget https://github.com/opencv/opencv/archive/3.4.4.tar.gz
- tar -zxvf 3.4.4.tar.gz
- cd opencv-3.4.4
- run configure as below:
