 Make sure that you are using the same Go version, and remember to set the git commit id (7 bytes):
 
 ```bash
-CGO_ENABLED=0 go build -o xray -trimpath -buildvcs=false -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid=" -v ./main

+If you are compiling a 32-bit MIPS/MIPSLE target, use this command instead:
+
+```bash
+CGO_ENABLED=0 go build -o xray -trimpath -buildvcs=false -gcflags="-l=4" -ldflags="-X github.com/xtls/xray-core/core.build=REPLACE -s -w -buildid=" -v ./main
