请确认git clone 的时候有没有添加 --recursive 选项

请问是什么问题？ 谢谢！

@lxl910915 你解决了这个问题吗？我源码编译的时候也遇到了：
/usr/bin/ld: cannot find -lps_network_static
/usr/bin/ld: cannot find -lseastar
/usr/bin/ld: cannot find -lcares-seastar

@peipei-pig 还没有解决，使用官方提供的xdl镜像来编译，也是这个错误。

@peipei-pig @lxl910915
确认git clone 的时候有添加 --recursive 选项，同时确认seastar lib编译成功。在cmake .. -DTF_BACKEND=1的时候会生成seastar lib。

cmake .. -DTF_BACKEND=1之后，生产了这些seastar相关的包：

./ps-plus/CMakeFiles/seastar_service.dir
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar/lib/seastar_server_client_lib.cc.o
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar/lib/seastar_client_lib.cc.o
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar/lib/seastar_server_lib.cc.o
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar/lib/seastar_request_processor.cc.o
./ps-plus/CMakeFiles/seastar_service.dir/ps-plus/service/seastar/lib/seastar_response_processor.cc.o
./ps-plus/libseastar_service.a

请问seastar lib编译是否成功？
@shanshanpt

[songyue1104]

seastar没有编译成功，查看一下seastar相关的编译日志，编译成功应该包含下面三个静态库：libcares-seastar.a libseastar.a libps_network_static.a

[shanshanpt]

@lxl910915 seastar_service是成功的，确认一下：
x-deeplearning/xdl/third_party/seastar/build/release/libcares-seastar.a
x-deeplearning/xdl/third_party/seastar/build/release/libseastar.a
x-deeplearning/xdl/third_party/seastar/service/build_script/libps_network_static.a
这三个是否存在了。
