build errors

[Fluxcapacitor]

I get many similar build errors. Running FC32. I tried 5.x and 6.x and got similar results. Am I missing a dependency?
Thanks!

Fixed by building SEQ 6.x with QTDIR=/usr/lib64/qt4 ./configure

Glad you got it working. You said you tried with both 5.x and 6.x - I can't say what the problem was for 5.x, but my initial thought for 6.x is that it was picking up your Qt3 headers instead of your Qt4 headers. I'd be curious to know the path of your Qt3 and Qt4 headers, as I might be able to tweak the configure scripts to help avoid it in the future.

SEQ6 builds, but only shows a blank window when you run it. Lots of errors on the console.

You need QT4 with SEQ 6. Guessing errors are related to using QT3.3 instead of 4.

[Fluxcapacitor]

with QTDIR=/usr/lib64/qt4 ./configure SEQ6 builds. I also tried uninstalling QT3. Same errors with SEQ6.

A few things to check/try (personally I'd do it in this order, but whatever floats your boat):

1. Try restarting X and/or the system. I've gotten "Bad Drawable" and similar errors when my system has updated the video/X/mesa packages in the background and I need to restart.

2. If your X session is running as your user but you're running ShowEQ as root, you may need to use xhost to give session permissions. Running



xhost +


as your user will set access wide open. If that works, you can narrow it from there. See `man xhost` for further details.

3. Try disabling the MIT-SHM extension by setting QT_X11_NO_MITSHM=1 in the environment.
