Keil uVision 5.23.0.0 compilation error(s) C4065E

I have a project in Keil uVision version 5.23.0.0 for STM32F103RC microcontroller and my project is located under C:\Projects\TestProj\LCDController\ on NTFS file system using Windows 7 x64 Ultimate as Virtual Machine in VMWare Player. Now, when I try to build project, I get following errors:

The error is related (I think) to Project Include paths: Keil Include Settings Why I am getting these errors and how do I solve them? Now, according to @LP's comment, this is the procedure for setting up Include dirs:
STEP 1 - Adding Inc directory
I am selecting Inc directory through Keil GUI:GUI Selection and when I select C:\Projects\TestProj\LCDController\Inc directory, my directory path gets truncated into ..\Inc.:GUI Selection 1GUI Selection 2. Is maybe bug in Keil and the path is wrong? Same happens for other two include dirs.

Solution

  • I don't know if it will be the case but this sometimes works.

    1. close project
    2. close Keil
    3. reopen project

    this is because Keil have many internals errors.
