XC8 Compilers - Discussion

Also as of v1.11 it is advisable to use quote marks to avoid preprocessor messing with your code. Check out documentation.

Damn. I lower my head in shame. Is Pic16 though but you're right everything is there.

No need to lower your head in shame, just read the manual, thu I won't use XC8 for PIC18, especially if I am going to use microchip library, at least not for now, current release of microchip applications library (v2012-10-15) includes support only for XC16 and XC32 compilers, which I think are more important than supporting PIC18. If you look at the manual, you can learn how to support both C18 and XC8, so in future you only need to change a #define to jump among compilers.

Where is that mentioned in the manual that comes with the compiler?

I think he mentions the conflict that can occur if you have predefined ON or OFF to specific logic levels as mentioned here:

Since the topic is quite complicated for me, I may be wrong but the solution i read out should be either placing #define after #pragma or to use quotation marks.

It's mentioned in the release notes that come with the compiler.  

Specification of config pragmaThe arguments to the #pragma configcan now be quoted.
You may prefer to quote the setting-value pairs to ensure that the preprocessor does not
perform substitution of these tokens, e.g., #pragma config "BOREN=OFF"

They are confusing people in this thread, better not go in depth ;- )

Does anyone know how to debug XC8 project in PROTEUS i can only load HEX file, but when loading COF debug file i cannot execute step by step through the code.

I have faced this problem with XC16 but there was an option to change the output file format to COFF and that works, but this option is missing from XC8

[metal]

Strange, I can debug main.c (single file project) in XC v1.11 without problems for both debug and release builds.

[Ahmad_k]

I have tried this on three different PC with mplabx 1.41 and xc8 1.11 without any success for debugging. This is strange.
Can you upload a small project to try on my Pc ?

[metal]

I am using MPLAB v8.88 and CX8 v1.11, send me your project and I will try it for you.

XC8 1.12 has just been released

("medicine" still seems to work...   )

[Okada]

Even I am not sure about the medicine but I think they refer to the link in the attached file in the topmost post at this link http://www.sonsivri.to/forum/index.php?topic=44014.0

[Okada]

Go here http://www.sonsivri.to/forum/index.php?topic=44014.25

download the xclm.rar which metal has posted or download the xclm.c which is posted by juvaan and compile it to get xclm.exe

[metal]

Download IDE and compiler from this link. The file you need to download is "codeblocks-12.11mingw-setup.exe". In case you don't have admin privilege on your PC, then you might opt to download this file "codeblocks-12.11mingw-setup_user.exe" instead, if you don't understand what I am talking about it, download the latter setup file.

Once download complete, simply follow the quick tutorial I created. You can also download project files in xclm.rar attachment.


Note: You have to be a member of 4shared.com in order to be able to download.

[metal]

attach your project here.  xclm.exe is working for me whatever project I open.. I mean, I am not having any of your errors.

[Okada]

If you want to compile yourself then create a new C project in Codeblocks and select MinGW GCC Compiler as the tool. Then add a new emply file to the project and save it as xclm.c. The copy and paste the code from the xclm.c posted in this thread. Then select Release as output type and build the program. xclm.exe will be in the Release/bin folder.

Yes, It can be used with any XC Compiler. Juvann also said that it also enables Pro mode of XC32++ Compiler in XC32 Compiler.

[metal]

 there is nothing wrong with my files... I don't understand what you are trying to do okada.. another post counter indian we 've got here..

[lcn]

Edit :

Finally, i found the following : ( for XC8 v1.11 and XC8 v1.12 )

Compiled Okada's file is not working for me.
PRO mode can be activated but compilation runs with free mode optimizations.

[juvann]

Icn are you sure to replace correctly the xclm.exe? In the last version the path of xclm is changed before there was a common path \program files\microchip\xclm\bin\ now every xc compilers has own version in bin directory, so for XC8 xclm is located in \program files\microchip\xc8\v1.12\bin\. You can replace every xclm.exe with the same fake xclm.

EDIT

PRO mode can be activated but compilation is done with free mode optimizations.

In MPLABX with XC8 compiler, you can choose if compile in Free, Standard or PRO, it's depend also from your license (fake xclm it's your friend).
In project properties: Conf: [name] -> XC8 global options -> XC8 Compiler -> on the rigth first combo Option categories -> Optimizations -> last option Operation mode, there are the three options.

[metal]

man... I asked you already to upload something that we can test here. We can't do guessing for you, if you seek help, find some way to allow us help you, this is going to a dead end, can't you see that already!? The same file size is compiling ok here, so, upload something that I or other  can compile to see if you are the only one having this problem, or all of us have it.

[LithiumOverdosE]

XC8 v1.20 has been released.

http://www.microchip.com/pagehandler/en_us/devtools/mplabxc/


Yet another update with no major improvements or correction of errors in PLIB.   

[metal]

Since microchip has outsourced this support task to indian companies, what do you expect!? There won't be fast major changes any more as Hi-Tech used to do.

[LithiumOverdosE]

I didn't know that. I supposed that Hi-Tech was contracted to do updates.

[metal]

I hope you are right.

[pumper]

no c-r-a-c-k crack for version 1.20 ?

[metal]

explain to me, why you are asking for the crack, also why do you write this word this way? This is forbidden here, write words correctly..

BTW, the existing crack is working fine, unless you found sth that is no longer supported by the current fix, read before you post and waste others time.
