subsurface builds, but dumps core at startup :(

[Cristian Ionescu-Idbohrn]

This is on debian unstable, subsurface master. Seen this happening
since a few days back.

The kernel reports:

Sep 11 17:36:33 host kernel: [11915775.481135] subsurface[24251]: segfault at 7fea4684ec60 ip 00007fea4684ec60 sp 00007ffd83e6ad38 error 15

This is what happens:

did you switch the qt version but did not rebuild the googlemaps
qtlocation plugin? it depends on internal api so a rebuild is needed...

did you switch the qt version but did not rebuild the googlemaps

Of course.

I think we have some stale information in our build trees that does't
have the right dependencies for qt changes.

I had a similar unexplained SIGSEGV that went away when building the
whole tree from scratch.

Note that for me, it was subsurface itself that had the issue, not
just the googlemaps plugin.

But it was literally a "I can't make sense of that SIGSEGV", so I just
nuked absolutely everything, so I'm not entirely sure what went wrong.

I've been having same issue (in debian/unstable) for a while now, and, as Linus
points out subsurface's build dir needs to be removed. I also remove the
googlemaps dir and then run build.sh

In my case, the binary in subsurface/build still SIGSEVs but the one
installed in install-root/bin (or system wide /usr/local/bin) runs
without map, throwing an error:

MapWidget.qml: cannot find a plugin named: googlemaps
qrc:/qml/MapWidget.qml:24: Error: Cannot assign [undefined] to QDeclarativeGeoMapType*

but at least runs.

I've also tried 4.8.1 AppImage, but it's also failing:

Absolutely. Just to point out that AppImage is not an option for

This seems related to recent changes in openssl package and is the

yep, i remembered about those openssl changes now and it think it was
a big problem with regards to Qt.
not sure what options we had, as this was an old discussion.

as a side note, i just verified that both the map widget and
Subsurface as a whole work on Ubuntu 17.10 from the 4.8.1 AppImage.

This is not really surprising, since my problems started exactly the day when

let me know. At the moment I wouldn't even know where to start. Sounds like a
Debian (and by inheritance a Ubuntu / x-buntu) package problem, doesn't it?

yes, probably.
i don't know where to start with this myself. not to anyone surprise
(i hope), my knowledge of how the QtLocation code works, is probably
only slightly more than others.

The packaging of private Qt headers changes - I believe they simply got
dropped (which is not entirely unreasonable given that they are, you know,
private). As a result in a completely clean build we are now downloading
them directly and a clean build on Debian and Ubuntu /should/ work - I
did one on 18.04 a few days ago and that went smoothly.

I deleted the /usr/src/install-root, /usr/src/googlemaps and /usr/src/

Alright. "a completely clean build" seems to work, but I wouldn't

I don't think I would use sanity and distro packaging in the same context.
That said, this one is partly our fault... we use a module that uses private headers from Qt.
Debian/Ubuntu decided to stop packaging those.
We don't notice and don't trigger the actions that do have the code for (downloading the
matching private header and re-compiling against them).

It would be nice if someone figure out a way to check this dependency and to automatically
do the right thing.

I'll admit that given how few people compile from source and how even fewer do so on
Debian/Ubuntu systems and how rarely Qt versions change... yeah, this isn't really high
on my TODO list, TBH

Looks like this:

Glad that I'm not the only one observing this, as this will hopefully direct
more attention to this problem (which has the nasty side-effect that I can't
run mobile-on-desktop).

i've commented on this before,

this is not broken in our AppImage builds.
also both my local builds with Qt 5.9.1 on Ubuntu 17.10 and Qt 5.9.0
on Windows 7 do not reproduce the SIGSEGV.

this makes the bug report relatively low priority and it ideally the
developers that are experiencing the issue should help with debugging
and get to the bottom of it.
my best bet is miss matched Qt private headers.
