I=92ve been doing some more testing and your port works in FreeBSD 10.0 = RC2 x64 as long as I don=92t use KDE. If using KDE I can get it to work = without the segfault by unsetting QT_PLUGIN_PATH in Konsole. =20 It does not work whatsoever with PCBSD 10 as of the p1-12-23-2013 = release. http://iso.cdn.pcbsd.org/10.0-RELEASE/amd64 I can=92t seem to track down what=92s so much different that it doesn=92t = work at all in PCBSD 10. I=92ve even started with just a plain session = with no extra environment variables. I suppose that part is not = necessarily a problem with your port. =20 I=92m wondering if perhaps the QT_PLUGIN_PATH issue was solved it might = also solve whatever is causing PCBSD not to work. For testing purposes = would compiling without hardening do any good, trying random versions of = gcc? Is there anything else I could try on my end to help track down = that issue? =20 Joe Maloney On Dec 17, 2013, at 3:02 PM, Bernhard Fr=F6hlich <decke@bluelife.at> = wrote: > Thanks a lot for your help!
