Just to let you know I updated my XC License Manager fix.

It patches if necessary and works with XC8, XC16 & XC32 on Windows, Linux & Mac OSX.

Open a command prompt, CD to your install folder (CD C:\Program Files (x86)\Microchip\xc8\v1.32\bin\) and type xclm[Enter].

Do you see any output?

Just to be sure...
Do you made a copy of the original xclm.exe and named it as xclm.old?

In the first time I also forgot to create the xclm.old but the new xclm warned me that it was unable to find the xclm.old.

may be your project setting is still not in PRO mode.

In the project properties: XC8 Global Options > XC8 Compiler > In Options categories select optimizations, you will find operation mode: Free, Standard and PRO

Hello,

i was not able to customize the hotkeys in XC8 V1.31 together with MPLAB 8.90.
Is this fixed in XC8 V1.32?

Best Regards

Now xc8 calculate the sha1sum of file xclm in a wrong way I don't understand yet
For linux version 1.32 with can change 2 byte at offset 0x33899 from 0x75 0xdd to 0x90 0x90 and should be work without problems with xclm compiled from my source code

I think Top has solved that problem already, it's a SHA0 checksum, not SHA1.

In my case, MAC OS X 10.9.2, it is not working.
First, I've renamed xclm to xclm.old.
Second, I've copied patch to bin folder.
Third, I've executed command "chmod 755 xclm" in order to add the execute attribute to xclm file.
Fourth, I've executed "sudo xclm". Nothing happend. Not even a warning message.

Am I doing something wrong?

Thanks in advance.

Please double check; open a terminal, change to the directory where xclm is and enter ./xclm

It worked!!!! Cheesy
The problem was related to the way I was trying to run xclm. Using the sintaxe you gave-me "./xclm" solved the problem.

Thanks a lot!!!

« Reply #96 on: September 06, 2014, 04:27:52 16:27 »

my complaint with the compiler is that it 'decides' what to compile in certain cases.   for no reason, when i was using a variable in a loop and loading values inside and reusing outside the loop and compiler (with and without optimisations enabled)  told me in the log file "variable unused" and did not compiled some lines of code, then i got weird behavior while debugging coff file..  does anybody have experienced that behavior?

I don't have experience with this compiler, but did you try with "volatile" keyword?

Long time ago I passed through this and it was, in fact, all about the volatile directive. (And that's how I learned how and when to use the volatile keyword  Smiley)

What is the perception of XC8 as compared to C18. I waited until recently to change since C18 is no longer supported and so far after a couple of weeks I am finding the amount of changes the need to be made to code is enormouse. Also ccp.exe seems to crash frequently for something as simple as an unneeded hex file being included.
I am thinking of sticking with C18 for a while longer.

Anyone have opinions on XC8 they could share with me.

Regards,
John.
