Title: Problem with relative file path
Post by: Crumbler on September 16, 2020, 08:49:50 pm

I'm writing a program using C++.
In one of my functions I need to open a .txt file using an std::ifstream.
This file is supposed to be located in the same folder as the executable.
I'm using a relative path.
However when launching my program directly from CodeBlocks, it can't find the file.
If I copy the .txt file into ...\bin\Debug and launch the executable manually, it works just fine.
Absolute paths work fine from CodeBlocks.
How can I make the relative path work when launching my program directly from CodeBlocks?

You must go to Project -> Properties -> Buil targets and set "Execution working dir" to bin\Debug

Thanks, this works for me.
Though I still have to get the text file copied to the folder when I build the project.
I used a post-build step with a cmd command:

cmd /c copy $(PROJECTDIR)\fShader.txt $(TARGET_OUTPUT_DIR)
cmd /c copy $(PROJECTDIR)\vShader.txt $(TARGET_OUTPUT_DIR)

Is there any way to do that more elegantly?

If your program does not modify the files you need to copy them only once.

Set the Execution working dir to the directory where the files reside, this way you dont need to copy them around.
