Question

我正在尝试使用

编译this git-repository（branch：feature-pybind）

option(BUILD_PYTHON_BINDINGS "Whether or not a binary python module should be built" ON)

This is the output of the compilation，但有趣的部分是：

显然我将-fPIC标志传递给clang。我真的不明白错误信息。什么是抱怨？我该如何解决这个问题？

Answer 1

链接时传递-fPIC但编译时可能不传递。编译时也应该传递它。

我认为这里真正的问题是你似乎试图用几个静态库创建一个共享库。那是不对的：你应该从目标文件创建它（当然用-fPIC编译）。

选项传递给链接器时出现“重新编译-fPIC”错误
