+# 简介
+输出gcl中的功能为C库
+
+步骤：
+- lib.go中编写要输出的函数:
+```
+//export Sm3
+func Sm3(in []byte, out []byte) {
+	d := sm3.Sum(in)
+	copy(out, d[:])
+}
+```
+- 生成go导出的C库(c-archive) 
+```
+go build -buildmode=c-archive -o libgcl_go.a lib.go
+```
+- lib.c中编写C包装代码
+```
+int sm3(void *data, int dataLen, void *digest){
+    // input check, omit
+
+    GoSlice in = {
+        data, dataLen, dataLen
+    };
+    GoSlice out = {
+        digest, 32, 32
+    };
+    Sm3(in,out);
+    return 0;
+}
+```
+- gcc编译gcl.c为动态库
+```
+gcc -shared -o libgcl.dylib -L. -lgcl_go gcl.c
+```
