【AnyQ】遇到的问题整理（二）

【一】version `GLIBCXX_3.4.22' not found

【问题描述】

./run_server: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./run_server)

./run_server: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /home/rd/caiyueliang/AnyQ/build/third_party/lib/libpaddle_fluid.so)

这是因为当前版本的libstdc++.so.6缺少GLIBCXX_3.4.22.查看当前版本的GLIBCXX命令为,

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

【解决方法】

安装libstec++

sudo apt-get install libstdc++6

如果还未解决,则可以终端运行如下命令:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update sudo apt-get upgrade
sudo apt-get dist-upgrade

再运行命令

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

这时候应该就能看到GLIBCXX_3.4.22了，说明安装成功了。

【二】运行run_server报错，依赖库找不到

【问题描述】

./run_server报错，依赖库找不到，如下图：

error while loading shared libraries: libpaddle_fluid.so: cannot open shared object file: No such file or directory

【解决方案】

1）ldd run_server

看下run_server指向的libpaddle_fluid.so是否存在（查看依赖是否存在）

./run_server: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by ./run_server)
linux-vdso.so.1 => (0x00007ffc55f66000)
libpaddle_fluid.so => not found

libglog.so.0.3.5 => not found
libcurl.so.4 => not found
libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fb65891a000)

libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb6577fa000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb657430000)
/lib64/ld-linux-x86-64.so.2 (0x00007fb65a782000)

2）依赖库找不到，要重新加依赖库：

ls -s anyq代码路径/build/third_party run_server路径

或

cp -r anyq代码路径/build/third_party/lib run_server路径

或

export LD_LIBRARY_PATH=anyq代码路径/build/third_party/lib
