Run cross compiled go program on original openwrt mips32 firmware

[bettermanbao]

Does anyone know the advantage of re-compile openwrt firmware with this repo? Currently I could run cross compiled go program on original openwrt mips32 firmware, but the performance is very poor.

I tried an UDP tunnel program which written in golang, but when it runs on my mips32 router after cross compiled, the transfer rate is only 2-3Mbps.

So I'm looking for some optimized metheds to run golang on my mips32 router now. Thanks!

My cross compile bin attahed, source code here: https://github.com/xtaci/kcptun

你是怎么编译的 编译时候的参数都有哪些 我编译出来的有7m呢

cd
git clone https://github.com/gomini/go-mips32.git
cd go-mips32/src
export GOOS=linux
export GOARCH=mips32 <== Change to mips32le if ramips
sudo mkdir /opt/mipsgo
./make.bash
cd ..
sudo cp -R * /opt/mipsgo
export GOROOT=/opt/mipsgo
export PATH=/opt/mipsgo/bin:$PATH
vi helloworld.go
go build helloworld.go

I have trouble when building mips32go on x86_64 machine, please help me:

To make the "unexpected relocation" errors go away, change the ./make.bash command to:
CGO_ENABLED=0 ./make.bash
