upgraded to Fedora 29 and bookworm just segfaults

[babluboy]

@captain-cavemaaaan Raising this issue to investigate why Bookworm segfaults on Fedora 29 (reported on issue #170)

Can you please run Bookworm in debug mode to get some more details: com.github.babluboy.bookworm —debug

[captain-cavemaaaan]

It segfaults before reporting anything. It apparently fails before it even gets into the main function; gdb backtrace shows

Hi @babluboy, the same thing is happening on my F29. Should I provide you a strace dump?

[babluboy]

@tchoutri Thanks for updating. I would need to set up a Fedora 29 VM to debug this issue.

From the above response it seems that it segfaults before any debug output...so no use asking you to run bookworm in debug...

Have you tried running any other Elementary app on Fedora 29...let me see if anyone has installed Bookworm on a lower version of Fedora...need to figure out what changed on Fedora 29

[tchoutri]

@babluboy Thanks for your answer!

Have you tried running any other Elementary app on Fedora 29

Absolutely not! Which one do you suggest I try?

[babluboy]

You can try my other app - Nutty (Network info App). Instructions here: https://babluboy.github.io/nutty/

[babluboy]

You can also try birdie - a nice Twitter client. Instructions here: https://quassy.github.io/elementary-apps/Birdie/

If Birdie installs fine, then I can check what I’m doing wrong in the start up code

[tchoutri]

I have a Core Dump with Nutty:

[babluboy]

Ok. Then it is consistent as I developed Nutty first and used that as a template to start with Bookworm....let’s see if you have success with Birdie

This line is missing a / after build: #29 0x00000000004098ce n/a (/home/tchoutri/Apps/nutty/buildcom.github.babluboy.nutty)

[tchoutri]

Ah yeah, I must have mistyped something in vim when I de-indented the log. EDIT: And here is the crash dump for Birdie, @babluboy:

[ForlornWongraven]

I just forked this on copr https://copr.fedorainfracloud.org/coprs/forlorn/bookworm/ and it builds just fine. Tested it on my Fedora29 box and it works flawlessly.

[babluboy]

@ForlornWongraven Many thanks for the update. Is there anything extra that you did to install Bookworm on Fedora 29?

Weird that both of the other two people in this issue had a core dump. Maybe there is something additional which worked the build for you. Could you please list your steps for installation?

Is copr linked to GitHub i.e. if I update the code on GitHub, will it automatically build the latest version on copr?

[ForlornWongraven]

No, i did not change anything. I only checked for required libs to build and added them to the SRPM that I use for COPR.

I have to manually start the rebuild once a new release has been published.

[tchoutri]

@ForlornWongraven Thank you very much! I've just opened Bookworm on my F29 from your COPR and it works perfectly!

[captain-cavemaaaan]

Yup; forlorn's version works ... the only obvious difference is that the original links libgthread-2.0.so

[babluboy]

No, i did not change anything. I only checked for required libs to build and added them to the SRPM that I use for COPR.

I have to manually start the rebuild once a new release has been published.

@ForlornWongraven Ok Thanks. I will mention the COPR on the Bookworm website. Is there a way that when I push a new Release into Github, the build on COPR can be triggered automatically ? Alternatively can you give me access to update the code and build when a new release is done?

[ForlornWongraven]

I have to check and test a bit. I'll update here once I know.
