gsnap截屏工具移植imx8m-evk

myzr_soft

主机平台： UBUNTU16.04
硬件平台：明远智睿MY-IMX8M-EVK
内核版本 ：Linux-4.14.98
交叉编译链：aarch64-linux-gnu
文件系统：fsl-image-qt5-validation-imx-imx8mqevk.rootfs.tar.bz2

设置交叉工具链:

$ source /home/jj/my-work/03_toolchain/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.env

$export CC=aarch64-linux-gnu-gcc

把源码包复制到虚拟机后解压:

$ tar xzvf jpegsrc.v9c.tar.gz

$ tar xzvf libpng-1.6.37.tar.gz

$ tar xzvf zlib-1.2.11.tar.gz

$ mkdir gsnap

$ cd gsnap/

$ mkdir jpeg zlib png install

$ mv gsnap.c /home/jj/my-work/transplant/gsnap/install

jpeg库编译安装:

$ cd ../jpeg-9c/

$ ./configure --host=aarch64-linux-gnu --prefix=/home/jj/my-work/transplant/gsnap/jpeg/

$ make

$ make install

zlib库编译安装:

$ cd ../zlib-1.2.11/

$ ./configure --prefix=/home/jj/my-work/transplant/gsnap/zlib/

$ make

$ make install

png库编译安装:

$ cd ../libpng-1.6.37/

$ ./configure --host=aarch64-linux-gnu --prefix=/home/jj/my-work/transplant/gsnap/png/

$ make

$ make install

gsnap编译：

$ cd ../gsnap/install/

$ $CC gsnap.c -o gsnap  -L/home/jj/my-work/transplant/gsnap/jpeg/lib/ -I/home/jj/my-work/transplant/gsnap/jpeg/include/ -L/home/jj/my-work/transplant/gsnap/zlib/lib/ -I/home/jj/my-work/transplant/gsnap/zlib/include/ -L/home/jj/my-work/transplant/gsnap/png/lib/ -I/home/jj/my-work/transplant/gsnap/png/include/ -lpng -ljpeg -lz -lm

将编译生成的gsnap可执行文件复制到开发板文件系统的/usr/bin/目录

打包库和头文件

cd ..

sudo tar -cjf gsnaplib.tar.bz2 peg/lib/* ./zlib/lib/* ./png/lib/*

sudo tar -cjf gsnap_include.tar.bz2 ./jpeg/include/* ./zlib/include/* ./png/include/*

将gsnaplib.tar.bz2拉到开发板文件系统的/usr/lib目录下

并且解压

sudo tar -xvf gsnaplib.tar.bz2

rm gsnaplib.tar.bz2

将gsnap_include.tar.bz2拉到开发板文件系统的/usr/lib目录下

并且解压

sudo tar -xvf gsnap_include.tar.bz2

rm gsnap_include.tar.bz2

运行gsnap fb.jpg /dev/fb0
