Program crashes before main.cpp

[SGaist]

Hi,

Since you have a debug build, can you use that one to generate a stack trace ?

[mar0029]

I can get a stack trace. Picture is here http://imgur.com/31AV4r0
tried using the embed image button but I couldn't get it to work.

[mar0029]

I did an objdump of my executable and searched the output for the offending line and could not find it. I found one similar but that doesn't mean anything.

[mar0029]

from here found some pertinent information. I am not running on Arch however.
Did a ldd of the exe and found both qt4 and qt5 libraries being used. Not sure if this helps.

[SGaist]

It sure helps, you have found your problem: two different versions of Qt being loaded at the same time.

What part of Qt 4 is getting loaded ?

[mar0029]

If all qt5 libraries look like libQt5XXX.so.... and all others are qt4 libraries, then it looks like i'm pulling the Svg, OpenGL, Gui, and Core qt libraries. below is the ldd of the executable:

[mar0029]

I am using some third party libraries that may or may not have been built with qt4. Should these be rebuilt?

@mar0029 said in Program crashes before main.cpp:

If your main app uses this libs. then most likely yes :) Unless there is good match between the Qt version used to create the app and the
version used to build the libs. Qt5 and Qt4 would be no good. Too huge version diff.

@mrjj
I am using qwt libraries. Did a ldd and the same qt4 libraries along with other similar libraries as the app appeared.
Looked in Makefile for qwt under ../qwt-6.1.3/src and found linker options to all qt4 libraries. Also with qt4's qmake.

Trying solution to build qwt with Qt5 located here

[mar0029]

That was it!

Thank you @mrjj and @SGaist for your help, also to @Wieland for your post on building qwt for qt5
