Importing App causes Seg Fault

[compleatang]

Every time I attempt to Import App, after selecting any file (including the samplecoin.html). This has happened both on OSX and Linux:

go 1.2.1
qt 5.2.1

After installing 5.2.0, the SegFault did not appear.
Stacktrace below:

[stephantual]

Totally correct - then again the 'warning warning this is bound to a specific version of qt' was a bit of a giveaway :)
I've updated my build guide at http://forum.ethereum.org/discussion/905/go-ethereum-cli-ethereal-simple-build-guide-for-osx and annotated my yt install video guide.

Thanks Casey!

[sjamayee]

Same problem for me.
When I import an app (genericcoin.html) then this happens.
Is there a work around for this?

Installation following (Go-Ethereum (CLI + Ethereal) simple build guide for OSX)

osx 10.9.2
go 1.2.2
qt 5.2.1

I'm going to try and replicate this. Everything is still working here.

Edit:
Confirmed that confirmed that anything over QT 5.2.0 breaks it. @compleatang and @sjamayee Please rollback to 5.2.0 or lower (don't forget to update CGO_CPPFLAGS) and it should work (again). Please let me know if this fixes it.

[sjamayee]

Rolled back to 5.2.0
With the help of: https://gist.github.com/gcatlin/1847248
Now it works.
Thanks for the help

[maran]

Good to know @stephantual could you update your excellent installation guide mentioning for now we are frozen on 5.2.0?

[compleatang]

@maran thanks. i have been using 5.2.0 for a bit now.

If anyone else has this problem on Ubuntu, the fix is to compile and use 5.2.0 from here and then follow the instructions on the QT page of the wiki to set the environment variables properly.

To use ethereal as a desktop app, I just built a small wrapper in my ~/.bin folder which sets the proper environment variables per the wiki instructions prior to launching ethereal and then exec that wrapper around ethereal from the *.desktop file.

I should have added this a while ago but I forgot.... Just updated the wiki.

[stephantual]

RC7 was not installing for me on 5.2.0, I had to flip to 5.2.1 to make it install.
I'm checking RC8 now

[stephantual]

RC8 fails to import samplecoin app with qt5.2.1 , confirmed.

[stephantual]

Right, there seems to be a brew problem whereby people are misled by error messages on install of a new release that somehow 5.2.1 is now supported (it's NOT).

If you are having problems with QT during install (ie, errors installing with messages along the lines of QT 5.2.1 not found), you probably have accidentaly brewed QT 5.2.1 or higher before downgrading to 5.2.0. Same thing if you find that 'import app' causes a 'panic' in the console.

I have no idea why that's happening, although it appears brew is being naughty and leaving links behind or similar issue.

To solve this problem, the workaround is as follows:

• upgrade to QT 5.2.1 by removing 5.2.0 then install QT 5.2.1
• installing ethereal should now work
• remove QT 5.2.1 and downgrade to 5.2.0
• restart ethereal

[stephantual]

Confirmed fixed on RC11 clean OS install. For those still having issues, see workaround above. Obscuren please close.

[mihi-tr]

Just ran into the same issue (running on Arch linux) is there a reason to use a very specific version of QT5?

[SimonTomlin]

I had the same issue running POC5 RC11
Ubuntu 14.04
I had already previously gone through the process of installing Qt 5.2.0
Used GO to update the installation

Putting the following in the ~/.bashrc file solved it for me (change the /home/simon of course)

export PKG_CONFIG_PATH=/home/simon/Qt5.2.0/5.2.0/gcc_64/lib/pkgconfig
export CGO_CPPFLAGS="-I/home/simon/Qt5.2.0/5.2.0/gcc_64/include/QtCore/5.2.0/QtCore"
export LD_LIBRARY_PATH=/home/simon/Qt5.2.0/5.2.0/gcc_64/lib

This is also in the wiki but posted here as well
