When I try to ‘./configure’ qjackctl-0.2.21, I get this error message and it quits:
checking whether QTDIR environment variable is set… no
configure: error: QTDIR must be properly set.
I downloaded some qt4 lib and dev stuff and tried setting some paths in .bash_profile, but I could not get it to run.
Any ideas on how to fix this? I hope it is okay to ask about this here. The sourceforge forum looks very deserted.
I don’t know how I missed it.
‘sudo apt-get install qjackctl’
I’m still having problems with qjackctl and jackd. When I launch qjackctl, I get these error messages:
06:23:33.033 Startup script terminated with exit status=256.
06:23:33.033 JACK is starting…
06:23:33.033 jackd -t5000 -dalsa -r44100 -p64 -n2 -D -Chw:0,2 -Phw:0,0

06:23:33.237 Could not connect to JACK server as client. Please check the messages window for more info.
06:23:35.921 MIDI connection change.
I tried ‘sudo apt-get build-dep qjackctl’ and a build-dep for jackd, but I still get the same error messages. Any ideas?
I tried to configure jackd 0.102.2 again and I noticed that it said “Build with ALSA support…false”.
For some reason the modified PKG_CONFIG_PATH that I put in my .bash_profile file keeps being dropped. Every time I open a new window I have to ‘. ~/.bash_profile’. I wonder how to fix this.
So I tried to rebuild jackd after sourcing .bash_profile and now it says ‘Build with ALSA support…true’.
But, now when I start qjackctl, I get more error messages. I will try to recompile qjackctl, if I can.

Any thoughts?
