Re: [Elecraft] KX3 Utility Segmentation Fault in Linux

[Eric Swartz - WA6HHQ, Elecraft]

Hi Knut,

Because it relates to problems using our utility software his posting is 
certainly pertinent here. We have a lot of users who run our Utility s/w under 
Linux and the solution to his problem will help others. Just because you are not 
interested in a posting does not mean its inappropriate and does not interest 
others on the list. (The delete key is a wonderful tool to quickly eliminate 
those you do not wish to read..)


Also, your posting below used the word 'period' at the end is what I referred to 
as rude and in essence orders them to take it elsewhere.


"Ths Linux gobbledygook has no place here, period."

It sounds like a parent disciplining a child. Neither a polite nor a respectful 
statement to another discussion list member. The last thing we want to do is to 
scare others away from asking questions or helping other on the list.


If you have concerns about a posting please feel free to contact the list 
moderator and do -not- post them to the list. The moderator is the only list 
participant allowed to make any decisions about the appropriateness of a posting 
and to contact a poster or post on the list about them.


Whew! - I guess people have been spending way too little time on the air and way 
too much time on the internet lately.. ;-)  I'm out of time on this topic - so 
let's end the discussion for now.


73,

Re: [Elecraft] KX3 Utility Segmentation Fault in Linux

[Chuck Milam, N9KY]

This seems quite relevant.  It literally has to do with getting
Elecraft-provided and supported software to function on an
Elecraft-supported computer operating system.

Given the software-driven nature of the Elecraft product line, you can
expect some discussion on software support issues on all of the various
computer operating systems supported by Elecraft.

I run my ham software on Mac, not Linux, but I’d tag that post with “Nice 
Elmering”. It was specific and clear.

Sorry for the meta-discussion, but I rode herd on netnews discussion groups for 
5000+ engineers at HP for about a decade. I’ve seen more than my share of good 
and bad net behavior.

Just wanted to post a quick update. Since this problem started
happening on 1 Mar 2018, I searched the archives and found the previous
version of lib32-harfbuzz.  After installing that version of the
package, now all the Elecraft linux utilities are working again on my
system.

https://archive.archlinux.org/repos/2018/02/28/multilib/os/x86_64/lib32
-harfbuzz-1.7.1-1-x86_64.pkg.tar.xz

You can install this on Arch systems with the following command:

pacman -U /path/to/lib32-harfbuzz-1.7.1-1-x86_64.pkg.tar.xz

If you do install this package, be sure to blacklist it from being
upgraded by placing the following line /etc/pacman.conf:

IgnorePkg   = lib32-harfbuzz

Re: [Elecraft] KX3 Utility Segmentation Fault in Linux

[David Woolley]

That is much more serious than a warning.  I'd expect it to be 
immediately followed by a crash with signal 3 (abort), rather than 
signal 11 (segmentation fault).  However, if this isn't the standard 
assert routine, I would expect any attempt to actually use hash_table to 
produce a segmentation fault.



The standard assert routine is a macro which tests the condition and, if 
it fails, logs the fact then call abort, which never returns.

Re: [Elecraft] KX3 Utility Segmentation Fault in Linux

[Thomas Kluge]

Hi Rob,

When I tried to start one of the utility programs today I got an error:

(k3util:2054): GLib-CRITICAL **: g_hash_table_insert_internal:
assertion 'hash_table != NULL' failed
I think this is just a warning but it was followed by a segfault...

All my Elecraft utility programs were affected (k3util, p3util,
kpautil).

I'm running Gentoo Linux which is up-to-date (most of the packets are
the stable versions) and I was not sure when it worked last time...
I've started to look a bit deeper into it and dmesg showed me first an
issue with the libexpat and then with libpng. I've downgraded both
packages to the following versions:
expat: from version 2.2.1 to 2.1.0-r4
libpng: from version 1.6.29 to 1.6.27

Now I still get the Glib-errors (warnings) in the console - but
everything works again. It might be the same problem the KX3util...

Best regards
Tom, DL3DTH

Hi Rob,

>From the Utility info on the web site:

X86-based Linux: GTK+ 2.8 or later, glibc-2.4, libstdc++.so.6 and cURL.
64-bit Linux requires 32-bit compatibility libraries.

If you do a search of the reflector archives you should be able to find a
list of the 32 bit libraries needed:


If that is not helpful drop an e-mail to supp...@elecraft.com, they have a
template with the needed libraries listed that they'll be happy to send you.

Re: [Elecraft] KX3 Utility Segmentation Fault in Linux

[Chuck Milam, N9KY]

Whoa, a Linux question?  Excellent.

Looks the HarfBuzz shared libraries got updated (probably along with your
window manager of choice) and the kx3util needs to be rebuilt (relinked?
Not certain of the proper dev-speak here) to reference the newer
libraries.   (Sorry if I'm preaching to the choir.)

See if you can get the core file to drop (you may need to do a "ulimit -c
unlimited" to ensure you get one) and analyze it with gdb for more
information.

I wonder if you can do a workaround and keep the libharfbuzz library files
that kx3util is looking for installed (maybe in /usr/local or somewhere
else handy?)

I'd test this myself, but I confess I gave up tilting at the windmills
years ago and use Win 10 for ham radio applications.  I do keep my Linux
boxes around for network and vulnerability management.  Right tool for the
job, and all that.
