Hello, I'm testing your VHDL CAD system at the moment on a linux-pc-elf-glibc6 machine. Both the tutorial sections of the distribution runs fine but the two X11 based tools graal and dreal don't run at all. They are simply scrolling their banner and then ... nothing. Even no error message. I tested a self compiled version and your binary linux distro (witch is a little out of date because it uses old libc.so.5 and old libm.so.5, that means it will have problems on newer linux distros like debian 2.0 or redhat 5.2) but always the same effect. Perhaps is because of the linking against the Motif library? I'm using lesstif-0.85 (www.lesstif.org) as a replacement which runs fine for most programs. Which motif version are the two programs build against: 1.0, 1.2, 2.0 or 2.1? Regards, Thomas Pasch PS: Its a little bit strange to compile your source distro. There is some mess with the numbering of your *.h and *.a files which can be fixed. Strangest thing is that Tas, Yagle and Fpmap are not included but normally you want to use them. I think that a binary tgz package with only this 3 programs would come in handy. If you want to compile at the moment you've got to download the full binary version also!
