编译

apt install openjdk-8-jdk
autoreconf -i
./configure --prefix=/home/zys/work/tool/lcm-1.3.1/lcm-install
make
make install

安装jdk是为了log-player-gui
也可以不编译java 和 py的，可以增加选项./configure
–without-lua --without-java

交叉编译

交叉编译不能使用x86的库。但是在做编译链接的时候默认的是使用本地库，即/usr/lib,/lib两个目录。因此，在交叉编译的时候，要采取一些方法使得在编译链接的时候找到需要的库。

./configure --without-lua --without-java --prefix=/home/zys/work/tool/lcm-1.3.1/lcm-arm-install --host=aarch64-linux-gnu LDFLAGS=-L/home/zys/work/tool/lcm_arm_LDFLAGS
