Hi
I am receiving:
*** ERROR L121: IMPROPER FIXUP
MODULE: C:\KEIL\C51\LIB\C51C.LIB (PRINTF)
SEGMENT: ?PR?PRINTF?PRINTF
OFFSET: 0068H
I have tryied to read threads about this, but cannot understand it since it appears in a .LIB file
Any help? Really needing it. Thanks for your time Dario
maybe Large model is ok
No, it is not OK, go for 'small' if you decide to change.
Please explain, if you can, why you think it is not ok for the OP to change from the compact model to the large model.
"Best practice is to solve the errors/warnings in the order they appear."
Absolutely - one warning very often leads to another!
Thus it's often best to address them one at a time and in order

Is the fixup error the first error that you are getting from the linker?
You really should start fixing all the warnings.
Plenty, arround 75 warnings.
How comes that deleting code (so deleting variables) causes that now the space is insufficient? do you have any linker warnings "... L16 uncalled segment ..." ?

Good one.
But i am working over an existing code that uses that model(compact). So i cannot change the code, i can go to the previous version and start the last changes again, but iÂ'd rather understand what caused this issue. How comes that deleting code (so deleting variables) causes that now the space is insufficient? ShouldnÂ't i expect the other way round. Deleting lines that declare variables (some of them static), shouldnÂ't free space of the pdata?
Since i have no time demanding issues, maybe Large model is ok, but i do not feel comfortable changing things without knowing was is going on...
thanks for you reply Dario
"I am a beginner...
C comp v7.20 Asse : v7.10 Link/Loc: v5.11"
Those are quite old versions to be starting out with...
" It worked fine but i modify code and does not work anymore."
Yes, you get that! This is known as breaking the code; such code is said to be broken!
;-)
But seriously:
"I have no idea on the PDATA space."
So don't use it!
Use either the Small or Large memory model instead:

I think you can safely leave PDATA for another day as an "advanced" topic...
I still don't get the problem. It worked fine but i modify code and does not work anymore. How come that i encounter this issue? I have no idea on the PDATA space.
I will need more assistance with this one. Sorry. I am a beginner...
C comp v7.20 Asse : v7.10 Link/Loc: v5.11
You are using the COMPACT memory model and the fixup error indicates a problem with the PDATA addressing.
Is the PDATA space within 256 bytes? What version of the toolchain are you using?
