Hello, I am compiling a software on Solaris with gcc as: gcc -traditional -O2 -DWANT_MFB -DWANT_X11 ..... It was made, but, when I ran the executable, I got: external error: no graphics packages; need to define either WANT_X11, or WANT_MFB Warning: can't initialize display device for graphics. Could someone please tell me what I might be missing? I appreciate your reply. Meng
