标题: gsnap截屏工具移植imx8m-evk
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/*

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


gsnap_include.tar.bz2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
