I compiled LyX from the source to install , something like ./configure (with prefix), make, sudo make install. I have no idea about Qt, I guess this is the language to develop LyX, maybe PyQt ? Never try to do programming in Qt, Py or PyQt. I should learn ? How I can fix this ? Thank you Regards, Waluyo
