Protobuf

  1. 下载:https://github.com/protocolbuffers/protobuf.git
  2. 解压,进入文件夹内
  3. 本地编译
./autogen.sh
./configure
make
sudo make install
./configure
  1. 交叉编译
make distclean
./configure --build=x86_64-pc-linux-gnu --host=aarch64-linux-gnu --with-protoc=protoc --prefix=/usr/aarch64-linux-gnu/protobuf
make
make check
sudo make install
--build表示本机环境,如果不清楚,在第一步,./configure时生成makefile时,查看打印信息,或插卡第一步生成的makefile
--host表示编译库的运行的环境,我的是arm架构cpu上运行,所以使用arm-linux,而生成的makefile中--host选项是arm-unknown-linux-gnu
--with-protoc=protoc,此选项的设置,是应为README.txt中所属,交叉编译需要增加此项,如果没有第一步得到部署protoc.exe,会出现错误,提示为:protoc找不到

opencv 本地

  1. 安装依赖项
sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg-dev libswscale-dev libtiff5-dev
sudo apt-get install libgtk2.0-dev
sudo apt-get install pkg-config
  1. 编译
make build
cd build
sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
sudo make install

opencv 交叉编译

  1. 安装依赖项
apt-get install libavcodec-dev libavformat-dev libswscale-dev
  1. 安装依赖库
export CC=aarch64-linux-gnu-gcc
./configure --prefix=/usr/aarch64-linux-gnu/opencvdeps
make
sudo make install
./configure --host=aarch64-linux-gnu --prefix=/usr/aarch64-linux-gnu/opencvdeps --enable-shared --enable-static
make
make install
cp scripts/makefile.linux makefile
vim makefile

makefile中找到zlib相关的两行,修改成实际的zlib/lib和zlib/include,
再找到prefix项,修改为你想prefix的目录
如果此处是交叉编译的话,还需要在cc那边把gcc修改成您系统的交叉编译器,比如:arm-linux-gcc

make
make install
CC=aarch64-linux-gnu-gcc ./configure --enable-shared --host=aarch64-linux-gnu --disable-asm --prefix=/usr/aarch64-linux-gnu/opencvdeps
make
make install
CC=aarch64-linux-gnu-gcc ./configure --enable-shared --host=aarch64-linux-gnu --disable-asm --prefix=/usr/aarch64-linux-gnu/opencvdeps
make
make install
cd ./build/generic

然后输入命令:

./configure --prefix=/usr/aarch64-linux-gnu/opencvdeps --host=aarch64-linux-gnu --disable-assembly
make
make install
./configure --prefix=/usr/aarch64-linux-gnu/opencvdeps --enable-shared --disable-static --enable-gpl --enable-cross-compile --arch=arm64 --disable-stripping --target-os=linux --enable-libx264 --enable-libxvid --cc=aarch64-linux-gnu-gcc --enable-swscale --extra-ldflags=-L/usr/aarch64-linux-gnu/opencvdeps/lib --extra-cflags=-I/usr/aarch64-linux-gnu/opencvdeps/include
make
make install
  1. 编译opencv:
mkdir build
cd build
cmake \
    -DWITH_PNG= OFF  \
    -DCMAKE_SYSTEM_PROCESSOR=aarch64-linux-gnu \
    -DWITH_FFMPEG= ON  \
    -DCMAKE_CXX_COMPILER=aarch64-linux-gnu-g++ \
    -DCMAKE_C_COMPILER=aarch64-linux-gnu-gcc \
    -DCMAKE_AR=aarch64-linux-gnu-ar \
    -DCMAKE_LINKER=aarch64-linux-gnu-ld \
    -DCMAKE_NM=aarch64-linux-gnu-nm \
    -DCMAKE_OBJCOPY=aarch64-linux-gnu-objcopy \
    -DCMAKE_OBJDUMP=aarch64-linux-gnu-objdump \
    -DCMAKE_RANLIB=aarch64-linux-gnu-ranlib \
    -DCMAKE_TOOLCHAIN_FILE=../platforms/linux/aarch64-gnu.toolchain.cmake \
    -DCMAKE_INSTALL_PREFIX=/usr/aarch64-linux-gnu/opencv ..
make                # 使用make -j,虚拟机有卡死的风险
sudo make install

openssl

  1. 下载:https://www.openssl.org/source/old/1.1.1/
  2. 解压,进入目录
  3. 交叉编译
export ARCH=arm64
./Configure linux-aarch64 no-asm shared --prefix=/usr/aarch64-linux-gnu/ssl CROSS_COMPILE=aarch64-linux-gnu-
make
make install

libwebsockets

  1. 下载
  2. 解压,进入目录
  3. 交叉编译
mkdir build
cd build
cmake .. \
-DCMAKE_INSTALL_PREFIX=/usr/aarch64-linux-gnu/libwebsocket \
-DCMAKE_SYSTEM_NAME=Linux \
-DCMAKE_C_COMPILER=/usr/bin/aarch64-linux-gnu-gcc \
-DCMAKE_CXX_COMPILER=/usr/bin/aarch64-linux-gnu-g++ \
-DZLIB_INCLUDE_DIR=/usr/aarch64-linux-gnu/zlib/include \
-DZLIB_LIBRARY="/usr/aarch64-linux-gnu/zlib/lib/libz.so"  \
-DLWS_OPENSSL_INCLUDE_DIRS=/usr/aarch64-linux-gnu/ssl/include/ \
-DLWS_OPENSSL_LIBRARIES="/usr/aarch64-linux-gnu/ssl/lib/libssl.so;/usr/aarch64-linux-gnu/ssl/lib/libcrypto.so" 
# 编译并安装
sudo make
sudo make install

qt

  1. 下载
  2. 解压,进入目录
  3. 修改qt-everywhere-opensource-src-5.9.6/qtbase/mkspecs/linux-aarch64-gnu-g++/qmake.conf文件
./configure -prefix /home/forlinx/OK3399/qt \
-opensource \
-debug \
-confirm-license \
-xplatform linux-aarch64-gnu-g++ \
-no-opengl \
-no-pch \
-shared \
-no-iconv \
-no-xcb 
  1. 交叉编译
./configure -prefix /home/forlinx/Downloads/qt \
-opensource \
-confirm-license \
-xplatform linux-aarch64-gnu-g++ \
-no-opengl \
-no-pch \
-shared \
-no-iconv \
-no-xcb 
# 编译并安装
sudo make
sudo make install
