hello, I am trying to build the HDSPmixer supplied by alsa-project. This application uses FLTK. I tried building it with FLTK-2.0.x but that got me nowhere. FLTK-1.2 gets me to the linker stage but not further. I get a series of errors, most of which I can append to this email (I forget how to redirect output to a file). Is this some misconfiguration of my build of the FLTK package, a problem with the HDSPmixer app (least likely), or some environment error on my part (most likely). Has anyone else had this problem? Everything below my signature is information that will help you to figure out if I am confused or if something is indeed amiss. Thank you for your help! -thewade my LD_LIBRARY_PATH=usr/lib64/qt-3.3/lib:/usr/local/lib64:/usr/local/lib:/usr/l ib64:/usr/lib my ld.so.conf include ld.so.conf.d/*.conf /usr/X11R6/lib /usr/X11R6/lib64
