CCS bootloader

[Tagge]

Hi,
I cant compile the CCS bootloader, ex_bootloader.c
It seems that a whole lot of declarations and other stuff are missing?
that is in the loader.c file, why?
Has anyone managed to compile the bootloader without larger modifications, or is there something wrong with my ex files and drivers?
Im using the ver: 3.242
I intend to use a pic 18f2525 at 4MHz
and I must be able to use a software UART, is this possible?
It seems that at least, bytefactorys codeloader, aint possible to use with a sw uart. Without major rewriting, it uses kbhit() and that only works, as supposed in that program, with HW uart? Has anyone rewritten this to function with a software uart? in that case, I would be very happy for some examples of what has to be changed.
Happy for all suggestions..

I created a project in MPLAB vs. 7.20, called Ex_bootloader,
and I added the Ex_bootloader.c file to it and compiled it
with PCH vs. 3.242. It compiled with no errors.
There are two warnings, but aren't important.

When I compile it in MPLAB(but using CCS as tool) I get this?

Maybe my loader.c is corrupted?
And i still wonder about using a SW uart and a bootloader, is there any solutions around?
Can one use the tinyloader and a sw uart? and is it possible to use it without a hw pin "trigger"?
/have a nice, bugless day
