# udp2raw build guide
|
||
|
||
the guide on how to build udp2raw to you own platform
|
||
|
||
## linux platform which supports local compile
|
||
such as PC,raspberry pi
|
||
|
||
##### install git
|
||
run on debian/ubuntun：
|
||
```
|
||
sudo apt-get install git
|
||
```
|
||
run on redhat/centos:
|
||
```
|
||
sudo yum install git
|
||
```
|
||
##### clone git code
|
||
|
||
run in any dir：
|
||
|
||
```
|
||
git clone https://github.com/wangyu-/udp2raw-tunnel.git
|
||
cd udp2raw-tunnel
|
||
```
|
||
|
||
##### install compile tool
|
||
run on debian/ubuntun：
|
||
```
|
||
sudo apt-get install build-essential
|
||
```
|
||
|
||
run on redhat/centos:
|
||
```
|
||
sudo yum groupinstall 'Development Tools'
|
||
```
|
||
|
||
run 'make'，compilation done. the udp2raw file is the just compiled binary
|
||
|
||
## platform which needs cross-compile
|
||
such as openwrt router,run following instructions on your PC
|
||
|
||
##### install git
|
||
run on debian/ubuntun：
|
||
```
|
||
sudo apt-get install git
|
||
```
|
||
run on redhat/centos:
|
||
```
|
||
sudo yum install git
|
||
```
|
||
|
||
##### download cross compile tool chain
|
||
|
||
find it on downloads.openwrt.org according to your openwrt version and cpu model.
|
||
|
||
for example, my tplink wdr4310 runs chaos_calmer 15.05,its with ar71xx cpu，download the following package.
|
||
|
||
```
|
||
http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/OpenWrt-SDK-15.05-ar71xx-generic_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64.tar.bz2
|
||
```
|
||
unzip it to any dir,such as ：/home/wangyu/OpenWrt-SDK-ar71xx-for-linux-x86_64-gcc-4.8-linaro_uClibc-0.9.33.2
|
||
|
||
cd into staging_dir ，toolchain-xxxxx ，bin .find the soft link with g++ suffix. in my case ,its mips-openwrt-linux-g++ ,check for its full path:
|
||
|
||
```
|
||
/home/wangyu/Desktop/OpenWrt-SDK-15.05-ar71xx-generic_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/bin/mips-openwrt-linux-g++
|
||
```
|
||
##### compile
|
||
modify first line of makefile to:
|
||
```
|
||
cc_cross=/home/wangyu/Desktop/OpenWrt-SDK-15.05-ar71xx-generic_gcc-4.8-linaro_uClibc-0.9.33.2.Linux-x86_64/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/bin/mips-openwrt-linux-g++
|
||
```
|
||
|
||
run `make cross`，the just generated `udp2raw_cross` is the binary,compile done. copy it to your router to run.
|
||
|
||
`make cross` generates non-static binary. If you have any problem on running it,try to compile a static binary by using `make cross2` or `make cross3`.If your toolchain supports static compiling, usually one of them will succeed. The generated file is still named `udp2raw_cross`
