ceph 编译时遇到的一些问题-526互联

在用git submodule update --init --recursive --progress下载子模块时，一些子模块加载有问题，包括rook-clinet-python

#######################################执行./do_cmake.sh时报错###########################

Make Error at /usr/share/cmake/Modules/ExternalProject.cmake:2847 (message):  No download info given for 'mgr-rook-client' and its source directory:

############解决办法###########
1.可以用在主目录下 用 git diff 看哪些模块下载有问题，例如
@@ -1 +1 @@ 
-Subproject commit 389cb68b87193358358ae87cc56d257fd0d80189 
+Subproject commit 389cb68b87193358358ae87cc56d257fd0d80189-dirty 
diff --git a/src/pybind/mgr/rook/rook-client-python b/src/pybind/mgr/rook/rook-client-python 
        --- a/src/pybind/mgr/rook/rook-client-python
        +++ b/src/pybind/mgr/rook/rook-client-python
2.然后在.gitmodules下看子模块加载路径path，和地址url
 
submodule "src/pybind/mgr/rook/rook-client-python"
 
path = src/pybind/mgr/rook/rook-client-python   

url = https://github.com/ceph/rook-client-python.git
3.删除rook-client-python
然后git clone https://github.com/ceph/rook-client-python.git 下载
下载下来后 放到src/pybind/mgr/rook目录下
