whoever is able to build graphviz successfully with ghostscript installed, can you report whether ~/.config/paperspecs exists on your system? Its absence seems to trigger the segmentation fault that ppetrov^ observed, according to the stack trace: https://dpaste.com/FGF8WP3GH

SiFuh: thanks for the report. I tested again on two different sysupped machines. The first one gave the segfault error shown in my previous stack trace. The second machine gave a "free(): invalid size" error, as shown here: http://sprunge.us/dibP4w
<SiFuh>
I am rebuilding ghostscript and then test again
<SiFuh>
Then I will rebuild groff and test again
<farkuhar>
The problematic files, /etc/paperspecs and /etc/papersize, are actually owned by opt/paper, not ghostscript or groff. In a container build they wouldn't be present (since opt/paper is not a hard dependency), and so the compilation errors would go undetected.
<SiFuh>
Yeah I saw the port was libpaper or paper or something
<SiFuh>
rebuilding ghostscript and groff didn't work

polkit the disease won't build says mozjs-91 is missing. Why is polkit even installed? I don't use anything special. It is just a flight simulator
<farkuhar>
SiFuh: I just got a successful build of graphviz. It was necessary to uninstall opt/paper and then rebuild ghostscript. If opt/paper is installed when ghostscript is built, then the ps2pdf program will look for the problematic files (paperspecs and papersize), which causes the segfault.
<SiFuh>
Oh okay, I will try that
<farkuhar>
Besides parsing the output of `ldd /usr/bin/gs`, there isn't a clean way to tell whether opt/paper was present when ghostscript was built. That's why my first fix (http://sprunge.us/GjK6Zw ) took the blunt approach of disabling PDF manpages regardless of how ghostscript was built.
<SiFuh>
This is an issue. Building against a pure system may work, but once other packages are installed it can fail
<SiFuh>
The only two solutions are 1) provide binaries or 2) compile the entire ports tree of core/opt/contrib/compat completely for each port update.
<SiFuh>
I can't think of any other solutions except change distros :-P
<farkuhar>
At some point it should no longer be a CRUX problem, but something that upstream needs to look into. But I don't see any report of ghostscript problems on the graphviz gitlab site.
<SiFuh>
I see it as a CRUX problem to be honest
<SiFuh>
But not in a bad way
ty3r0x has quit [Ping timeout: 268 seconds]
<SiFuh>
But you are correct.
_moth_ has quit [Ping timeout: 264 seconds]
<farkuhar>
If upstream graphviz is providing the file cdt.3 and a Makefile that tries to process it with groff and ps2pdf, then they ought to test those commands across a variety of possible configurations of groff and ps2pdf. We as distro maintainers shouldn't have to patch the Makefile because their testing was incomplete.
<SiFuh>
Yes, and you are right. But it is also a CRUX problem since pull non-maintainer deps is a possibility but not really looked into much
<SiFuh>
It is mostly left to the user to figure it out
<SiFuh>
farkuhar: it worked here
<farkuhar>
SiFuh: polkit also suffered from insufficient testing. beerman neglected to check whether it would build against the version of mozjs in our ports tree, not realizing that polkit requires mozjs91. In the meantime you can adapt beerman's fork of opt/mozjs78 and create your own port for mozjs91.
<farkuhar>
Otherwise, if nothing else on your system depends on mozjs78, just remove mozjs78 and install duktape instead. That should allow polkit to build cleanly.

Might wait until 3.7 is released
<SiFuh>
What I should do is make my own CRUX SDR version
<SiFuh>
Keep the ports a little bit out-of-date to maintain stability and build everything against itself

So?

HAHAHA
<ppetrov^>
although it does not matter

right, right...

I was kidding but I laughed so loud I the dogs a block away are barking
<ppetrov^>
heh..
<SiFuh>
Just join, dump your issue, and leave. Someone will look at it, look into it and maybe something happens
<ppetrov^>
they may find me here...
<SiFuh>
You know #crux and #crux-devel are basically the same right? Just the off topic gossip is spoken here in #crux
<SiFuh>
Although some members have moved to #crux-devel only because they are hard working and #crux gossip can be distracting.
<SiFuh>
Apart from that, it is the same. Just less distracting
<ppetrov^>
i am kidding
<ppetrov^>
i am a bit drunk
<SiFuh>
I drink 24/7
<SiFuh>
Even at work
<ppetrov^>
are you complaining or bragging about it?
<SiFuh>
Enjoying it
<ppetrov^>
that's the spirit
<SiFuh>
Today I tested the new Fuji C-50 burner. Cut my distillation time from 1 hour and 40 minutes to 30 minutes.
<ppetrov^>
and by spirit i don't mean hard drink
<SiFuh>
The heat up time, not the complete distillation (Sorry)
<ppetrov^>
so, you brew your own?
<SiFuh>
Yeah, I make 90 percent I guess of all my alcohol.
<SiFuh>
I sell maybe 99 percent of the vodka.
<ppetrov^>
this legal there?
<SiFuh>
I don't seel my beer or Asian alcohol. That is for me and the family/friends
<SiFuh>
Hell no
<SiFuh>
Muslim country
<ppetrov^>
:D
<SiFuh>
Australia and NZ it is legal.
<SiFuh>
But in Australia if the distiller is over 5 litres you should apply for a licence from the tax department.
<ppetrov^>
interesting
<SiFuh>
Beer and wine is legal in Australia
<SiFuh>
NZ all alcohol manufacturing is legal regardless of size
<ppetrov^>
sounds great
<SiFuh>
The world is changing
<SiFuh>
SO for now, I am just a moonshiner and my friend is a bootlegger :-)
<ppetrov^>
heh
<SiFuh>
I have 320 litres to do. So will take about 14 days
<ppetrov^>
well, i don't know much about distillation but sounds impressive
<SiFuh>
I tested the new distiller a couple of days ago and it failed. Blew up the tempered glass stove, then the next day popped the distiller. So now I am back on the basic pot still to get the job done before the mash becomes vinegar
<SiFuh>
Heat the shit, catch the shit, cool the shit, collect the shit.
<ppetrov^>
ye, this i know :p
<SiFuh>
That is it. But when you start going fancy, you can make a home made bomb.
<SiFuh>
The best moonshine (in my opinion) is made in a pot still using recycled mash. I don't care copper or stainless steel.
<SiFuh>
A thumpkeg is a bonus for flavour. But it can create back pressure
<SiFuh>
Then there is a lot of other stuff but the topic will become huge explaining it all
<ppetrov^>
maybe make another channel dedicated to it? like #crux-distil
<SiFuh>
Actually I would if there was other moonshiners here
<SiFuh>
were*
<ppetrov^>
maybe they are hiding?
<SiFuh>
But living in Malaysia, knowing this, from when I was young. My neighbour was a brewer. I use to mess around helping him and not really caring, just doing what he said, would end up being my lively-hood. That was in the late 80's early 90's. Who would have thought?
<SiFuh>
Probably better to create or even check if a #distiller channel exists
<ppetrov^>
i'll join
<SiFuh>
#moonshiners and distillers doesn't exist
<ppetrov^>
is it complicated to create a channel?
<SiFuh>
No
<SiFuh>
But I need to check plurals too
<SiFuh>
I haven't searched for channels in decades. Wondering how
<SiFuh>
LIST This command could not be completed because it has been used recently, and is rate-limited.2
<ppetrov^>
i have no idea what this means
<SiFuh>
#homebrewtalk.com and ##homebrew exist, both empty
<ppetrov^>
go get 'em
<ppetrov^>
does it cost anything?
<SiFuh>
No
<SiFuh>
I will make a distillers channel
<SiFuh>
I will need to think about the name though
<SiFuh>
Maybe moonshine/r/s
<ppetrov^>
in Fallout 3, there's moonshine drink
<SiFuh>
There was in Matric 1 too
<SiFuh>
Tnak made it, good for two things
<SiFuh>

<ppetrov^>

<SiFuh>
I don't know how these fuckers can make it illegal
<ppetrov^>
brewing your own?
<SiFuh>
I open a tin of pineapple slices and throw into a sealed container and put in the refrigerator and 1 month later it is turning into alcohol
<SiFuh>
BOOM excise tax, you broke the freaking law
<ppetrov^>
everything turns into alcohol

the mircale of fermentation

I make rice tea and close the lid. The amylase in my salive breaks the rice down into fermentable sugars and the yeast in the air consumes it.
<ppetrov^>
well, not everything, but sugers, at least...
<SiFuh>
BOOM excise tax, you broke the freaking law
<SiFuh>
Lactobacillus is a bacterium that can create alcohol, I use a small amount of it in my beer
<SiFuh>
Yeast is a (like a fungus) that is used mostly for creating alcohol. It is everywhere. :-P EVERYWHERE
<ppetrov^>
amylase breaks sugers into smaller sugars...
<SiFuh>
I can wash and not cook vegetables and soak in water and it ferments because of the natural yeast
<SiFuh>
BOOM excise tax, you broke the freaking law
<SiFuh>
Yeah yeast can't digest long or large amounts of sugar
<SiFuh>
So you need some enzymes to break it down smaller
<ppetrov^>
you need enzymes to convert it
<SiFuh>
It is why the Tibetans spit into the warm cooked rice first before turning it into Chang (Like Sake)
<ppetrov^>
you know, it's bee qwuite some times i studied these...
<SiFuh>
For barley we usually let the barley germinate. The germiantion process creates amylase. Then they dry it to stop the process and then use it for making beer
<SiFuh>
I never knew it myself until I read a French and a Korean paper about it
<SiFuh>
That was in 2019
<ppetrov^>
heh
<SiFuh>
For me it was Malt, sugar, yeast
<SiFuh>
Didn't know Malt was malted barley. Malted barley was semi-germinated then dried barley
<SiFuh>
In Australia we just bought a tin of malt syrup and made beer from that
<SiFuh>
Yeah that is it
<SiFuh>
Acetlydhyde is interesting though. It depends on temperature the amount you get
<SiFuh>
And even though that image is correct, they should swap the Ethanol and Acetyldehyde around
<SiFuh>
Majority comes after
<SiFuh>
Alcohol fermentation occurs inside your intestinal tract as well
<SiFuh>
I have a processed sugar free diet. But those how eat processed sugar create alcohol everytime they eat. Some even get Candida or yeast infections :-P
<SiFuh>

[core.git/3.6]: ca-certificates: update to 20220719
<farkuhar>
jue: we figured out why ps2pdf was segfaulting during the graphviz build. It seems to happen only if ghostscript was built on a system with opt/paper present. ghostscript built on a clean system will not segfault when processing the requested file(s).
