MPLAB xc32 v1.10 has been release

http://www.microchip.com/mplabxc32windows

New Features in MPLAB® XC32 v1.10

Support for C++

Standard C++ Library

[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!

XC32 1.21 is out!

http://www.microchip.com/mplabxc32windows

testing medicine...

[marcodassi]

seems to work
BTW, no major improvements in 1.21... "only" new parts, header & linker scripts updates

[Catcatcat]

released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.22

[Manuel]

FYI: released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.30

Manuel.

[marcodassi]

Manuel: Thank you, but: where is it?

edit: found! on the mchip site (but is still listed as 1.22)

[Catcatcat]

Do not believe what is written, and just click and you will be happy

[Catcatcat]

MPLAB® XC32 Compiler v1.31 !!!

[Manuel]

FYI: released a new version Windows (x86/x64) MPLAB® XC32 Compiler v1.32

'njoy

Manuel.

[marcodassi67]

They check for modified xclm file as is in latest XC32 release.

hello petarp, you mean latest xclm doesn't work with XC32? I've tried it some time ago and it seems working,,,

[petarp]

Hi marcodassi67, Yes XC32 v1.32 checks for modified "xclm" file.
Here is the fix for XC32:
 1. Open "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\cc1.exe" file with hex editor.
 2. Find these bytes "75 6a 89 5d" and replace first two bytes with "90" ("90 90 89 5d").
 3. Do same with "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\cc1plus.exe" and "C:\Program Files\Microchip\xc32\v1.32\bin\bin\gcc\pic32mx\4.5.2\lto1.exe" files.
 4. And use latest "xclm" file from here.
It works for C++ too.

Regards.

And here is the patcher for XC32. Great work, petarp  
I guess there's only a matter of time before XC16 needs the same treatment...

[juvann]

Now xc32 calculate the sha256sum of file xclm.
In linux version the sum of origina xclm is 4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e
with a perl command with can replace it with new sum

Code:

sha256sum /opt/microchip/xc32/v1.32/bin/xclm
perl -pi -e 's/4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e/NEW VALUE OF SHA256SUM/g' /opt/microchip/xc32/v1.32/bin/bin/gcc/pic32mx/4.5.2/cc1
perl -pi -e 's/4fae1d53570ebffe637d8c5f77789ecbe690f67af65d0e3af8474bfee479239e/NEW VALUE OF SHA256SUM/g' /opt/microchip/xc32/v1.32/bin/bin/gcc/pic32mx/4.5.2/cc1plus

[Catcatcat]

MPLAB® XC32 Compiler v1.34

[frnando]

Sorry, but the patcher/xclm is still working with v1.33?
Thanks.

[bluex]

v1.34 cannot be activated with provided medecine. read details here

[Manuel]

Even updated 1.40 XC32 part support

https://www.microchip.com/mplabxc32-ps-windows

Manuel

[Armageddon]

Fix for XC32 v1.40.

Steps:
 1. Open "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\cc1.exe" file with your favorite hex editor.
 2. Find and replace these bytes "0F 85 CC 00 00 00 8D 44" with "90 E9 00 00 00 00 8D 44".
 3. Do same with "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\cc1plus.exe" and "C:\Program Files\Microchip\xc32\v1.40\bin\bin\gcc\pic32mx\4.8.3\lto1.exe" files.
 4. Use latest "xclm" file from here, i.e:

xclm

Code:

int main(){
    return 2;
}

Tested under Windows 10 and MPLAB X IDE v3.15.

More info: http://www.jubatian.com/articles/turning-on-optimizations-in-microchips-xc32/

Note: I used the same technique that petarp, but now:

90 = nop
E9 = jmp
00 00 00 00 = $ + 5

Cheers.

Update MPLAB® XC32 v1.44

Fixed in v1.44

XC32-720
In the MPLAB XC32 v1.43 release, the linker incorrectly treated all symbols in the input object files as weak. This meant that non-weak symbols could not override weak symbols. The correct behavior of weak and non-weak symbols has been restored.
XC32-709
When compiling and linking with Smart IO and the Legacy Libc, printf() and related functions may print incorrect output. Under some conditions, the format specifier could get printed. This issue has been fixed.
XC32-708
In XC32 v1.43 and earlier, When compiling and linking with the Non-Legacy Libc, printf() and related functions did not handle the %ll conversion specifier correctly when the value has non-zero bits in the upper 32-bit positions.
XC32-707
XC32 v1.43 emitted a linker error when applying the coherent attribute to a zero-sized section. (Ex: uint8_t __attribute__((coherent)) ary[0]; ) The linker now emits an error when it can't allocate only non-zero sized sections.

The medicine works !!

[Git]

Any medicine for XC32 2.05 please?

[Catcatcat]

Compared the work of version 1.44 and 2.05
- 3 - Optimize yet more favoring speed
medicine "standard" 

as for my project, it makes no difference, everything works!

[Git]

I looked with a magnifier, but still no difference to see

Plenty of    0F 85 CC 00 00 00 xx xx
but no       0F 85 CC 00 00 00 8D 44

[tumbleweed]

I don't know about the patch shown here, but the medicine in the 'XC - software only' thread appears to work for XC32 2.05

http://www.sonsivri.to/forum/index.php?topic=44014.0

[adamantium]

Any medicine for XC32 2.05 please?

I can also confirm the old xclm.exe works, just rename the one in the /bin directory to xclm.old, copy in the xclm.exe patcher and run as administrator.

[MetaMetal]

xc32 v2.15 is out.
medicine works fine.

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.20 (link to the latest compiler version)

everything is working!

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.40 (link to the latest compiler version)

everything is working!

[Manuel]

updated to MPLAB® XC32/32++ Compiler v2.41

Thank you , still perfect.

X!

[Catcatcat]

MPLAB® XC32/32++ Compiler v2.50 (link to the latest compiler version)

everything is working!

On my projects, the new version of the compiler has shown an improvement in optimization for data in RAM (packs 1.2.51).

[marcodassi]

MPLAB XC32 32++ Compiler 3.00

Just tested with the "classic" medicine... no luck this time - the patch crashes cc1.exe

BTW, there are some undocumented changes... specifically, in the gcc options, some of them have changed name

[Catcatcat]

And V3.0 did not work for me 

[Top]

I just tested my fix with a simple XC32 v3 project and it seems to work fine.

Tell me how to reproduce this issue.

[danymogh]

Here use this medicine, it should work for all future V3.xx as well

[Catcatcat]

Here use this medicine, it should work for all future V3.xx as well

also, pray for me to become rich.

Thank you very much! The vaccine works!
To work, I additionally had to update .NET 5.0 Desktop Runtime (v5.0.6) https://dotnet.microsoft.com/download/dotnet/thank-you/runtime-desktop-5.0.6-windows-x64-installer

yes, sorry I forgot to mention you need .net 5 or above runtime to run the SHA-Patcher

[marcodassi]

Thank you very much, danymogh!

Does this medicine works for XC8 and XC16 too, or is for XC32 only?

> also, pray for me to become rich.
Done, are you rich now?

Best regards

Hi.

Is the medicine compressed or has only the file extension been changed?

It doesn't work for me.

Posted on: June 17, 2021, 04:10:44 16:10 - Automerged

Hi.

Is the medicine compressed or has only the file extension been changed?

It doesn't work for me.

It has been compressed, sorry for the misunderstanding. It has worked correctly.

Regarding the new version (3.xx), there are changes in the concept of the C language.

My projects without harmony v2 or v3 compile perfectly with version XC32 v3.00, but those who use that tool, the compiler gives errors. Any suggestions what can be done?

[Catcatcat]

I was unable to activate version 3.01. Who managed to accomplish this? Please share.

[Top]

My fix seems to work okay on v3.01 too.

Tell me how to reproduce this issue.

[danymogh]

I was unable to activate version 3.01. Who managed to accomplish this? Please share.

my fix , like i said , should work for all 3.xx version and i checked for 3.01 and it still works.
do a clean install and it should fix any problem

[Catcatcat]

Thank you, it turned out to be activated! The problem was that I launched the cmd in normal mode, and not as an administrator.

I have fixed the problem with Harmony 3 and XC32 version 3.xx.

The solution is the next:

1. Harmony 3 packages must be updated.

2. Open the MHC and regenerate the project code.

The new generated code has the property of detecting if the compiler version is 2 or 3 is being used, depending on that it modifies the code so that there are no compilation errors.

There is no solution for Harmony 2 version, you must use the latest version of xc32 (2.50)

[Manuel]

XC32 v4.0 Arrived...

:-)

Manuel.

[Catcatcat]

Installed, performed wellness procedures, it works!

[danymogh]

Where did you get the installer file? it's not available online on the website.

[giappolo]

Link is on first post, i.e.

[Catcatcat]

But today the license stopped working for both 4.00 and 3.01

[Manuel]

Used TOP medicine.

A small example for AT compiled properly including Analysis too.

Take Care,

Manuel.

[sparkybg]

Fresh install. It does not find any licenses. xclm -status only says: "Microchip XC License Manager Version: 2.30".

This is both for 3.01 and 2.50.

I am using the medicine from this post:
http://www.sonsivri.to/forum/index.php?topic=45710.msg200806#msg200806

Any advice what to do?

Try Google.com

Trying it multiple times every day since it exists. Still no luck. 

[Catcatcat]

The medicine does not help and no dancing with a tambourine helps.
I noticed that everything was fine until the last Windows update, after that the licensing stopped working.

[sparkybg]

Used TOP medicine.

Manuel, please tell us where to download this "TOP medicine" from, because it is a bit confusing (for me at least) which one should we use.

@Catcatcat: If it will help, I can make a Windows 7 or Linux vitual machine and work from there if someone can confirm that there is a medicine wotking in this OS.

I only need MIPS16 option to be active, because the project is using the legacy libraries for PIC32 USB and refuses to compile without it.

But literally a couple of days later, an error appeared and what is interesting for both version 4.0 and 3.01.
After that, I tried to reinstall the compilers, when checking the license, the result is zero.

[Manuel]

Just for information,
v.4.00 is not present anymore on the site...(have no idea why)

The microchip always has universal links to download the copiers. This link will always download the latest version.

Yes CatCatCat,

but if you follow the link from the site you will never be able to get it now.

That's the strange....I just wanted to underline the fact.

Hi.

The medicine works correctly with the latest version 4.21, but only with MX and MZ devices.

For ATSAM32, it isn't possible, since it is literally another compiler dedicated to them.
