So QT should always be considered if available, but somehow it seems to pas= s into oblivion.

Subject: Re: bug#14672: QT port for ARM within guile
Hello,

Excuse my ignorance, but what is a "QT"? I can tell you'= re not referring to the widget toolkit.

Also, I believe Guile uses pthreads on most platforms, so if you'r= e running Linux on ARM (which is the common case on ARM nowadays, I think),= you should have threads. Unless you want userspace threads.

Best,
Noah

Hello,

Hope you can help me with this. Do you know what the status of this port was? Did it work? I would like to add a Q= T for ARM into the SystemC Open Source Project and I=92m looking for a good starting point.
