64bit Linux

Hi All,

Is anyone running CCS in 64 bit Linux? I keep getting a segmentation fault on startup.
See below:

Don't know about Linux (too old to learn...) but going from 32bit to 64bit Windoze has been a real PITA !! I need a 2nd PC (32bit) to run most of the 'old' stuff I understand.....

I'm thinking since it worked in 32bit it has to be a 64bit problem...

Thanks temtronic,

I'm going to go with that until proven otherwise.
Guess, I'll step back and do the PIC development on the old OS.

Why not email ccs support?

They are always responsive when I email.

OK, I have to ask WHY go to 64bit Linux ? You say everything is fine in 32bit mode so to me there's no real reason to migrate to 64bit.

Just curious why you need to upgrade ?

cause....'If it ain't broke, don't fix it'....

Most of the 32bit OS'es are losing support now adays. We aren't allowed to use 32bit operating systems unless it is a specialized targetted platform, and then it has to be documented with a risk mitigation plan, etc.. I can't speak for the OP, though.

Not to mention the RAM limitations in 32 bit systems. You can't even reach 4gb.

Also, Windows 7 will be losing patch support in the coming year. Things are getting shaken up.

I must admit I'd have expected the 32bit libraries to have made it work.
Problem is that obviously this is pretty much only tested by CCS on one
install, and some tiny difference could be enough to make it give problems.
Whereas on the Windows version they get hundreds of users trying it,
the actual 'base' of Linux 64 users is probably rather small...
You say you have the 32bit libraries. You might need a chroot for it
possibly?. Have a look at:
<https://jblevins.org/log/ubuntu-chroot>
<https://debian-administration.org/article/356/Installing_apps_in_a_32-bit_chroot_in_AMD64_Debian_system> there are similar ways of doing this
on most Linux binaries.
My guess would be that there is some small part of the 'assumptions' made
by the compiler that is dependant on it's original install environment.

Thanks Ttelmah,

I'll look into that.

So I made an attempt with chroot to the root directory of the 32bit OS that CCS is installed on. from the terminal, I attempted to run ccsc --version Here is the unfortunate result:

root@glenn-LX6820:/opt/picc# ccsc --version

Thought maybe I had to run it as root:

root@glenn-LX6820:/opt/picc# sudo ccsc --version
sudo: ccsc: command not found
root@glenn-LX6820:/opt/picc#

I'll keep trying, maybe I'm just missing something.

I just moved from Linux Centos7 to Ubuntu 19.1. My CCSC +FH binary crashes now with

!) ./ccsc.bin +fh
Runtime error 0 at FFD8FD54
Segmentation fault (core dumped)

I've installed as many lib32 compatibility libs as I can find and no luck.

I ordered a new version of the compiler, but after reading this thread it looks like it's not going to fix the problem. Is CCS planning to support this product on 64 bit linux, or is it time to move to an ARM with gcc or PIC32 using the Microchip compiler?

Really, talk to CCS.
It is long enough now that they should have been able to work out what is
happening, and even if they can't reproduce the problem, if they can tell
you how their test system is configured, it will give hints as to what changes
may be needed.

As Mr. T says, call CCS ! I'm guessing there aren't too many LINUX-CCS users, even fewer 64bit installs, so not a lot of time gets spent on it ? It could be some other program,ap, DLL, ?? is clobbering your setup so KNOWING what the CCS did is kinda important.
Heck, you might become an 'Alpha' tester and get a deal !
I'm assuming you HAVE to run 64Bit Linux ? If so that 'hurts' as you've spent a LOT of time on this when the 'regular Windows' version works fine.
