pandas/lib.so: undefined symbol: is_complex_object

先啰嗦两句，起因是最近更新到了ubuntu22，然后我司的python2项目安装了python2后无法启动。报错如下

/home/wxp/.config/pyenv/versions/wj/lib/python2.7/site-packages/pandas/lib.so: undefined symbol: is_complex_object

各种重装，重新build from source都无法解决。最后终于在相似的问题中找到了解决方案。主要原因是ubuntu 22中gcc默认使用新的标准，导致pands中inline函数编译不正确。

CFLAGS=-fgnu89-inline pip install --force-reinstall --no-cache --only-binary :all: --global-option=build_ext pandas==0.11.0
