为什么我无法使用相对路径在CLion中打开文件？

Question

I seem to get errors when trying to open an std::ifstream if I use a relative path. Though it works fine if using an absolute path.

Is there something I need to add to the CMakeLists.txt? (I'm pretty new to using cmake) Or is it just a problem in CLion?

Answer 1

It's CLion. You have to set the Working Directory in your compilation options. (under run > edit configurations)
For example:

Because CLion works in an other directory on ubuntu under ~/.clion10/system/cmake/generated/[id_of_project]
