Question

我在理解导入带有使用setup.py安装的扩展的python包时遇到了一些问题。包是'gmes'，它有4个扩展模块，它们是.so文件。

首次尝试加载包gmes会出现有关符号c0
加载包含该符号的扩展模块_constant.so，然后重新加载'gmes'包，清除该符号错误并引入有关第二个扩展模块'_pw_material.so'的新错误。
明确加载第二个扩展模块对第三次尝试加载'gmes'时丢失的消息没有影响。

我得到的结果略有不同，具体取决于我从哪个目录启动python。看起来我错过了一些关于pythons包和扩展的约定的简单方法。

还有一个问题建议使用LD_LIBRARY_PATH和ldconfig。我只尝试过LD_LIBRARY_PATH但它没有用。

任何想法都赞赏！
