undefined - 如何设置哪个 libstdc++.so 与 libarrow.so 链接？

问题描述

我在 Redhat 7.4 上使用 gcc7.2 从源代码构建 libarrow.so 和 pyarrow。尽管如此，我仍然遇到以下错误，这似乎是由使用不同版本的 gcc（4.8.5 与 7.2.0）引起的。

[u0017649@sys-97675 ~]$ python
Python 3.7.1 (default, Dec 14 2018, 19:46:41)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyarrow
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/u0017649/anaconda3/lib/python3.7/site-packages/pyarrow/__init__.py", line 47, in <module>
    from pyarrow.lib import cpu_count, set_cpu_count
ImportError: /usr/local/lib64/libarrow.so.13: undefined symbol: _ZN5boost6system16generic_categoryEv

我检查了 ldconfig，它清楚地表明 libarrow.so 与来自 Redhat OS（使用 gcc4.8.5 构建）的 libstdc++.so 链接，而不是与我自己使用 gcc7.2.0 构建的链接。

[u0017649@sys-97675 ~]$ sudo ldd /usr/local/lib64/libarrow.so.13

我重新检查了我的 LD_LIBRARY_PATH，但看起来没问题。 

[u0017649@sys-97675 ~]$ env | grep LD_ 
LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/lib64:/usr/local/lib:/usr/lib64:/usr/lib:/lib64:/lib:

我做错了什么 ？我该如何解决这种情况？请帮忙。

解决方案

没关系。我傻到在 ldd 前面白白使用 'sudo'，这改变了 LD_LIBRARY_PATH 的环境变量。没有 sudo，正确的 LD_LIBRARY_PATH 设置，我可以看到一切都很好。
