#1927 Build fails for qt4 and pdfviewer/PDFDocument.cpp

[Anonymous]

Hi,
More build issues. I am also having a build issue with qt5 but I will submit a separate ticket for that. Here is what I am getting with building against qt4:

Thank you again.

[Jan Sundermeyer]

you have actiavted "phonon" ?

[Fred]

No, I didn't intend to. Just what qmake did or something like that. I am using the texstudio.SlackBuild from slackbuilds.org

[Fred]

I corrected the SlackBuild. There was a reference to PHONON=true in the section that sets flags for qt4. I am waiting for the build to complete. It looks like it works though.

When I build against qt5 though I get a segmentation fault. with the following back trace from gdb:

Different issue but thought I'd mention it anyway. Thank you for your help. It is very much appreciated.

[Fred]

Texstudio built against qt4 and is running without issue so far. The enabling of PHONON was the problem. I corrected the flags in the SlackBuild for qt4.

Thanks again!

Regards,

Fred

[Jan Sundermeyer]

please open another report for qt5 issue, otherwise it is difficult to find it again later on

[Jan Sundermeyer]

@Tim,@Benito: do you want to fix the phonon build ?

[Tim Hoffmann]

As I'm mostly building on windows for which we've never provided phonon support, I'm not intending to work on it.

Anyway, is there really a need for phonon support? The only application I can think of are presentations with embedded videos. But I've rarely seen them in real life. And still one could use an external viewer in this case. Likely, you won't need to watch the video while working on the document.

[Lars]

I'm running into the same issue. Texstudio is failing to build with qt4 and PHONON=true. Is there a fix for this?

--Larry

[Jan Sundermeyer]

don't build it with PHONON=true ?

[Lars]

So you won't support PHONON anymore?

[Tim Hoffmann]

Tried to fix is: hg 6220 (5f9e814ad8f2)

However, this is untested because I currently don't have a build environment including phonon.

[Fred]

Thanks Tim. I'm trying to build it now.

Fred

Since I don't have time to setup a qt4 build environment for phonon, all I can offer is trying to fix your build errors one at a time. Sorry that it's a bit cumbersome, but it's currently the only way to do something about this at all.

Please try again with hg 6221 (5903721d443a)

[Fred]

Tim,

I pulled from hg and built texstudio successfully with PHONON=true in the SlackBuild script. Thank you for your help. I have to test with something like the knitr tex examples to see if the animation works as I don't have any documents of my own that use the animation features.

Regards,

Fred
