移植ubux、libubox

https://cmake.org/cmake/help/v3.12/manual/cmake-toolchains.7.html   //cmake官方学习网站

 

1. download

git clone https://github.com/json-c/json-c.git
git clone http://git.openwrt.org/project/libubox.git
git clone http://nbd.name/gitweb.cgi?p=luci2/ubus.git
git clone https://git.openwrt.org/project/ubus.git

2. build

- ubus
cmake -DBUILD_LUA=OFF -DCMAKE_INSTALL_PREFIX=../install/ -DCMAKE_TOOLCHAIN_FILE=../toolChain_ubus.cmake .
make

- libubox
cmake -DBUILD_LUA=OFF -DCMAKE_INSTALL_PREFIX=../install/ -DCMAKE_TOOLCHAIN_FILE=../toolChain_libubox.cmake .
make

- json
cmake -DCMAKE_INSTALL_PREFIX=../install/ -DCMAKE_TOOLCHAIN_FILE=../toolChain_json.cmake .
make

下面是几个cmake文件，把编译器路径，和json、libubox、ubux路径换成自己的就可以了
