+# Developing C/C++ Applications for DragonOS
+
+## Compilation Environment
+
+  DragonOS has partial binary compatibility with Linux, so you can use the musl-gcc compiler from Linux. However, since DragonOS does not currently support dynamic linking, you need to add the compilation parameter `-static`.
+
+For example, you can use the following command:
+```shell
+musl-gcc -static -o hello hello.c
+```
+to compile a hello.c file.
+
+When porting existing programs, you may need to configure `CFLAGS`, `LDFLAGS`, and `CPPFLAGS` to ensure correct compilation. Please refer to the actual requirements.
