XC8 is based on HiTech PICC + PICC18 with compatibility mode for C18.
XC16 is ex-C30.
XC32 is ex-C32.

Since MPLABX 1.20 all XCx tool chains are present.

However, now my Proteus tool chain disappeared but that's hardly a problem for the moment.

Hello

You will find user guide and instruction to add compiler plugin to mplab X here

The link in dl.txt is not working any more.

Original post updated; new links in dl.txt.

I just tried this fix with XC8 1.10 and the compiler stays in Free mode.

With XC8 1.00 and 1.01 everything is fine.

Try replacing xclm.exe in C:\Program Files\Microchip\xc8\v1.10\bin folder.

[LithiumOverdosE]

Ah, so that was the trick. In previous versions it was enough to replace it in C:\Program Files\Microchip\xclm directory. 

[marcodassi]

Just downloaded XC8, XC16 and XC32 1.10; tested with current fix; results:

- XC8 1.10 - fine, works in Pro mode with all optimizations;
- XC16 1.10 - fine, works in Pro mode with all optimizations;
- XC32 1.10 - DOESN'T WORK - the compiler stays in Free mode, no optimizations allowed

I've tried to copy xclm.exe in the "\Program Files\Microchip\xc32\v1.10\bin" folder too, with no luck.

Please fix it, if possibile
Thank you very much in advance!

The version v1.41 of MPLAB® X IDE is available from here : http://www.microchip.com/mplabx-ide-windows-installer

It solves some of compilation and compiler detection issues with XC compilers but introduces new problems too..

[SpaleKG]

Just to confirm that current fix works fine on Mac OSX on all XC compilers.

I have one question about MPLAB X IDE.
How to configure project when using bootloader in PIC. For example bootloader uses first 200 bytes of FLASH memory, so how to tell compiler to generate hex to start after that ?

[jukinch]

SpaleKG:
     you can use a project specific "linker script" to start after that memory location.

[odessa]

You can set a code offset from within MPlab X. If you right click your project - select properties - then click linker - Choose additional options from the drop down menu on the right you'll see a code offset option.

Does this move interrupt vector adresses too or I need to do that somehow?

I'm pretty sure you can't move the interrupt vector addresses.  Some of the PIC processors have alternate interrupt vector tables which follow directly in memory after the primary interrupt vectors but that doesn't help you much with typical bootloader related issues.

You can however point the interrupt vectors to a jump table that resides in your application memory space that can then be overwritten when you load a new firmware.  That way you can update interrupt function locations without overwriting the first segments of memory.

Mplab XC8 v1.11

Download:

[marcodassi]

XC8 1.11 works with latest "medicine" too

[j2mb]

I'm using MPLAB X IDE v1.51 and compiler XC8 v1.11 and is working well! 

[metal]

u'r kidding me!?

[TucoRamirez]

the thing that confuses me about mplabX is that even if my code is ok, mplab show me "!" signs ... (even with XC demos or the application libraries -that compile 100/100 ok ) ...  anyway, the config tool inside is quite nice  

but, mplabx is crappy slow on my eeepc netbook (1G Ram ... )  ...but in a 4GB elitebook hp runs ok ...

Well, same here on Win7 x64.

I have a lot of problems with this as well.  They don't have the parsing working quite right yet.  It's especially bad in XC8

[gamegurus]

After install, How to check, if XC compiler is free or PRO versions?
I tried all ways 1) cmd 2) compile test and see output in MPLABX
but didnt find any such info.

[TucoRamirez]

check the project properties, in the part of compiler tou will see the options of optimisation

[Gallymimu]

I don't think that tells you, all options always show in the properties.

You need to run the compiler and look at the output.  It should say it is running in free mode and omniscient code generation is disabled if it is in free mode.

XC8 v1.12 is working ok with this fix. Tested on Ubuntu 12.04.
