Dear Sirs, I am a new Alliance new user, very new. Following the instrcution of the first tutorial "addaccu", when I type in the command "dreal -l addaccu" after I "make" to ready all the database, it comes up a message that stop the process, which is : ld.so.1: dreal: fatal: libSM.so.6.0: open failed: No such file or directory Killed I check all my LD_LIBRARY_PATH on my Solaries 2.51, there are no X11 library called "libSM.so.6.0". Could you please tell me where I can get this library, or other way to work around. ps. the Alliance 3.2b is th version I use now. Thanks, Rcihard Kuo Maojet Tech. Taipei, Taiwan
