Hello,
if i try to compile, i get this message:
*** FATAL ERROR L210: I/O ERROR ON INPUT FILE: EXCEPTION 0021H: PATH OR FILE NOT FOUND FILE: LED.obj
The compiler should make the LED.obj or is that wrong? Whats the problem here?
Please help me
Bye!

Yes there is a license issue, but a Keil FAQ says, that it should be compiler. How to fix that?
KEIL FAQ says, that the compiler should compile. The licence problem is only information that there are no updates any longer.
Another clue:
If I start a new project with 2 header files and the LEd.c and the Startup File. He create a Startup.obj, but not the LED.obj after the compiler ends.
Have you enabled the SRC directive?
Is an LED.obj being created anywhere on your hard drive?
No .obj file on hard drive!
How do I enable the SRC directive? Clue: The startup file and the LED.c are in the same directory in KEIL!
http://www.keil.com/support/man/docs/c51/c51_src.htm
"The SRC directive creates an assembler source (.SRC) file instead of an object (.OBJ) file."
But i want the .obj file.
If i uncheck "Generate Assembler SRC File" he compiles but brings up 3 warnings:
Build target 'Target 1' assembling STARTUP.A51... compiling LED.c... LED.C(1): warning C500: SERIAL NUMBER EXPIRED linking... *** WARNING L1: UNRESOLVED EXTERNAL SYMBOL SYMBOL: ?C_START MODULE: STARTUP.obj (?C_STARTUP) *** WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL SYMBOL: ?C_START MODULE: STARTUP.obj (?C_STARTUP) ADDRESS: 000DH Program Size: data=9.0 xdata=0 code=15 creating hex file from "LED"... "LED" - 0 Error(s), 3 Warning(s).
Then, obviously, you must not check 'Generate Assembler SRC File'
Or, if you do, you must also check 'Assemble SRC file'.
"i uncheck 'Generate Assembler SRC File' he compiles..."
So you did have it checked, then?!
"...but brings up 3 warnings"
Does your LED.c file contain a valid main() ?
Yes there is a valid main()!
I have to uncheck Assemble SRC File and check Generate Assembler SRC File -> result: 3 warningsbut it compiles
If I try anything other -> the error I mentioned in the beginning!
No - that's wrong!
I think you need to just throw that project away, and start again from scratch with a good, clean project; eg,
http://www.keil.com/support/man/docs/uv4/uv4_ex_hello.htm
result:
Build target 'Simulator' compiling HELLO.C... HELLO.C(1): warning C500: SERIAL NUMBER EXPIRED linking...

Your project is messed-up, and you are floundering with this.
It's impossible to debug remotely on a forum like this.
Just throw that project away, and start again from scratch with a good, clean project; eg,
Follow the tutorial carefully!
Build target 'Simulator' error - can't create command input file 'HELLO.__i' Target not created
Did you follow the tutorial carefully?
Is this for your job, or for a hobby?
I reinstalled uVision4 and it worked with a project in Evaluation mode.
But if I add the LIC in license management, he has two warnings:
Build target 'Target 1' assembling STARTUP.A51... compiling LCD2.c... LCD2.C(1): warning C500: SERIAL NUMBER EXPIRED linking... *** WARNING L52: EVAL VERSION USED BEFORE, REBUILD ALL *.OBJ FILES MODULE: LCD2.obj (LCD2) Program Size: data=13.0 xdata=0 code=221 creating hex file from "LCD"... "LCD" - 0 Error(s), 2 Warning(s).
LCD2.C(1): warning C500: SERIAL NUMBER EXPIRED
You know why you get that one.
*** WARNING L52: EVAL VERSION USED BEFORE
And that seems to be just an obvious statement of fact!
Again, is this for your job, or hobby?
only hobby....maybe later for job!
