Scribus 1.5 (unstable trunk) segfault on slack 14.2.

joenew · 08-08-2017, 12:49 PM

Hi all,
I'd like to try scribus 1.5, but my seems to be just a 1.4.6 package for linux distribution: Slackware 14.2 64 bit.
I finally found a "Slackbuild" script to create a package of 1.5.3 scribus version, so I prepared the building directory and then launched the compile. All seemed working for the best: no errors returned and a new package installed.

But... when I launch "scribus" from the shell it return "segmentation fault".
How could I know what's the problem?

Is there someone using a working 1.5.x Scribus version on slack?

Thanks a lot in advance!

scribus segfaults in slackware-current as well.
What follows is the backtrace.

Code:

Thank you for your report!

I have not enough skills to "decrypt" all that output, but hope someone can explain where the problem is and how to try to solve.
Bye!

I chatted a little with a-l-e on irc then, as he suggested, I opened a ticket on their Mantis: after a while jghali suggested that maybe it was the compiler.

so I added these lines before the cmake block in the SlackBuild

Code:

export CC=clang
export CXX=clang++

and this way scribus >= 1.5.3 doesn't segfault anymore when launched.

I tested it on current but I think it should be the same on stable.

Thanks ponce!
Works like a charm

I confirm it works!
Thanks to Ponce and "jghali" of scribus dev team.

I tested compile and run on slackware 14.2 (the present stable version).

In my case I had to fix the SBo, gperon previous slackbuild script as ponce as suggested:

replace following lines:

Code:

elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2 -fPIC -std=c++11"

with theese below (-std=c++11 has to be removed, it is no more compatible with 1.5.3 scribus version nor with "clang/clang++" compiler:

Code:

elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2 -fPIC"

Then added to cmake the following otpion:

Code:

-DWANT_CPP11=1

And the Ponce above suggest:

Code:

export CC=clang
export CXX=clang++

I notice GPeron has edited his slackbuild too, now you can find it at:

Thanks to all for replies, suggestions and script provided!

Until next time!
