Hello,
I`ve added the .c with .h files to project. After removed them both from folders. But now got compiler error. Seems compiler still searching for it. How to fix it?
Using Keil uVision
*** Using Compiler 'V5.06 update 6 (build 750)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin' Build target 'ROOM_LIGHT' compiling hdc1080.c... "no source": Error: #5: cannot open source input file "..\Src\hdc1080.c": No such file or directory ..\Src\hdc1080.c: 0 warnings, 1 error "ROOM_LIGHT\ROOM_LIGHT.axf" - 1 Error(s), 0 Warning(s). Target not created. Build Time Elapsed: 00:00:00
1. I`ve restarted the IDE, but error stays
2. I pressed "Batch Clean" in IDE, compiled but error stays.
3. I`ve manually deleted all files in Output folder, compiled again, but error stays.
After re-compile in Output folder created hdc1080.d file again.
IlgarSky said:I pressed "Batch Clean" in IDE, compiled but error stays.
really?
You need 'Clean Targets', and then 'Rebuild all target files':
Ok. I did it now exactly. Cleaned all files in Output folders. But no changes.
You mean you clicked on the 'Clean Targets' option on the 'Project' menu - as shown?
And then you clicked on the 'Rebuild all target files' option?
Remember that we can't see your screen, and we can't see what you're doing - so it's up to you to describe clearly and completely and precisely what you have done.
I understand. I did exactly as you displayed in picture. The is no such file in Src and Inc folders. Cleaned, Rebuilded but error stays.
Now I cheat the compiler: Created blank hdc1080.c and hdc1080.h files and put them to the project folders. Compiled. Error gone :)It is strange but worked.
Note that the project files are just plain text - so you can look at them in a text editor, and search for references to your mystery files...
And, again, you're not #including the .c file in another .c file, are you ... ?
I looked that .c file in Notepad++. Found nothing unusual. It was about regular I2C data transfer procedure for HDC1080 temperature sensor. Here it was:
