+#### objtool 缺失
+
+今天在 deepin 上编译时，遇到了下面的问题：
+
+```
+make[4]: *** No rule to make target 'tools/objtool/objtool', needed by '/home/chn/repo/xmurp-ua/debug/openwrt-sdk-18.06.5-x86-64_gcc-7.3.0_musl.Linux-x86_64/build_dir/target-x86_64_musl/linux-x86_64/xmurp-ua/xmurp-ua.o'.  Stop.
+```
+
+解决办法是，把系统的 objtool 复制过来，然后再编译。
+
+```bash
+mkdir ./build_dir/target-x86_64_musl/linux-x86_64/linux-4.14.151/tools/objtool
+cp /usr/src/linux-headers-4.15.0-30deepin-generic/tools/objtool/objtool ./build_dir/target-x86_64_musl/linux-x86_64/linux-4.14.151/tools/objtool/
