XC8 Compilers - Discussion

Confirm XC8 v1.41 ok!

take care,
Manuel.

[PM3295]

I can't get v1.41 to patch. It keeps telling xclm.old not found when running xclm as admin, although it is there because if I run xclm.old it gives the "XCLM: Bad command line passed to license manager ..". I tried it on two different machines. Any ideas? This was a fresh download and installed from Microchip site yesterday.

Thanks.

Hello PM3295,

just check this:

Code:

>md5sum xclm.old
6f40ab2c41589af127f3fc0918758c15 *xclm.old

>md5sum xclm.exe
10ced13a23a1129ecf040c32556d4b99 *xclm.exe

>dir xclm.old xclm.exe
01/10/2017  18:26         1,149,952 xclm.old
06/19/2014  22:58            26,624 xclm.exe

>xclm
OK

Attached xclm.old.


Best Regards and Good Luck

With your sample xclm.old it patched like a dream. So something must be different. I will investigate. Thanks

After original  xc  compiler setup  complete,  the xclm.exe (xclm.old) generated depends on your pc. (mainboard serial etc.?)
Another xclm.exe cannot be used in your pc. (not sure)

[PM3295]

It worked on complete two different PCs. One uses a i-7 motherboard and the other an older pentium quad core. I am happy it worked for me!

The frontend to the XC8-Compiler is xclm.exe. And not xclm.old.
Thats why i included xclm.old in my post.
If Microchip has changed something, who cares...

To my knowledge only the RSA-keys are patched to a known state.
May be that someone can bring more light into this.

Would You please check also this:

Code:

>md5sum xc8-v1.41-full-install-windows-installer.exe

MPLAB v3.61, XC8 v1.42, Win10, xclm.exe renamed in xclm.old patching done messages but looks like is in free mode.
You have compiled in FREE mode.
Using Omniscient Code Generation that is available in PRO mode,
you could have produced up to 60% smaller and 400% faster code.
See http://www.microchip.com/MPLABXCcompilers for more information.

Best regards.

If you would have read a bit more, eventually you would have found that you need to replace the xclm.exe file in MPLABX BIN folder also (MPLABX\v3.61\mplab_ide\bin). It has been discussed already.

[2Code]

Working like a charm after I copied as advised top's xclm.exe on C:\Program Files (x86)\Microchip\MPLABX\v3.61\mplab_ide\bin. Mea culpa.
Recap:
  rename xclm.exe in xclm.old in C:\Program Files (x86)\Microchip\xc8\v1.42\bin, copy cure and run it as admin
  replace xclm.exe in C:\Program Files (x86)\Microchip\MPLABX\v3.61\mplab_ide\bin with cure

[Manuel]

NEW...

Confirm... XC8 v1.43 + MPLABX 3.65 ok.

Take care U All!

Manuel.

[odessa]

1.43 you mean ... and yes it works fine 

[mars01]

New XC8 compiler, version 1.44. Patch works. No difference against v1.43 in the compiled size in a certain test scenario.

[alichan]

Hello I noticed with xc8 1.44 1.45 only 2 files are patched but cgpic.exe and cgpic18.exe, aren't patched.
It looks the compiler is in PRO mode anyway. Is it ok with those files?

[tumbleweed]

All 4 files were patched when I installed v1.44.

btw v1.45 is available

[alichan]

Sorry, typo. It is version 1.45.

1.44 is pacthed all the 4 files,  but not 1.45.

[mars01]

You made me curious and I uninstalled the XC8 1.45 compiler and reinstalled it. In my case the only thing that is not showed here is that I overwritten also the xclm.exe from MPIDE/BIN folder with the fixed file. Just from habit, I don't know if it's needed anymore.

The result is in the picture below which shows that all 4 files are patched. Win10 X64 with latest updates.

...

I uninstalled and reinstalled, and used the last xclm i found in the thread,  just in case mine is not updated.... same result:

D:\Microchip\xc8\v1.45\bin>xclm.exe
Patched 40 bytes in file ./picc.exe
Patched 40 bytes in file ./picc18.exe
Patched SHA in 2 of 4 files

The only difference with your image is I'm  not using the default path for installing... but i never had problems until 1.45.
I'm using W7 Home Premium 64b, admin rights, etc... As I said I had no problem with previous versions.

Update: I also tried with 1.44, installed in custom path, same result with only those 2 files patched.
Update: Installed 1.45 in default path, same result... only 2 files patched.

Could you point to the exact post/link of the xclm you are using? or upload yours to some site to download. I'm curious if I'd get the same results than you using the same xlcm (just in case mine is not the same).

Nombre: xclm.exe (26.624 bytes), ‎19‎ Jun 2014

This is the xclm i was using, but I also used the xclm in http://www.sonsivri.to/forum/index.php?topic=44014.msg186926#msg186926, after some search. They look the same, at least they have the same hash.

So I don't know what is happening and why the cg---- files aren't being patched.

Attached there is a MEGA link with the xclm files.

[Top]

If you see "Patched SHA in 2 of 4 files" then 2 files couldn't be written to.

Check file permissions/attributes on cgpic.exe & cgpic18.exe.

[alichan]

Alo.

I could patch the files finally, but I'm not still sure what happened. It looks some process was owing those files magically for no apparent reason.

Thanks for helping.

[Dadabe]

Hello,
I just understood, using the procedure under DOS indicated by mars01, that it is absolutely essential to patch as Administrator. Everything is done under Win10-64 bits as indicated in the DOS window. Like what, sometimes, a small picture is worth more than a detailed statement. Many thanks to mars01 in may18.
Best Regards.

hi

to download use this direct link:
http://ww1.microchip.com/downloads/en/DeviceDoc/xc8-v2.00-full-install-windows-installer.exe

to patch the PICs compiler:
rename the xclm.exe, in folder C:\Program Files\Microchip\xc8\v2.00\bin, to xclm.old and put the cracked xclm.exe (26624 bytes) in this folder
copy/paste the xclm.old and xclm.exe to folder C:\Program Files\Microchip\xc8\v2.00\pic\bin.
In the last folder run the xclm.exe

regards
mitsos

PS I'm not sure if the AVRs compiler needs a patch

[koky]

with Xc8 2.00 the patch don't work

[lm317]

The patch works fine, as mitsos described with Xc8 2.00 . Tested.No problem.
