The folks at Cadence Design specifically will not support their latest software on older Redhat systems, and will not support their older software on newer Redhat systems. I wish I had more input to the System people at my company who control all this, but I have to live with what they provide. :( I like the idea of security vulnerabilities and will run it by my sysadmin.

You could have told us that at the beginning! Sorry, I didn't think it was relevant. Use: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/afbacher/LFS71/lfs80/lib That worked, even after removing the link I had found to be necessary. Thanks! Another question: For making bzip2, the LFS book has the commands: make PREFIX=/usr install cp -av libbz2.so* /lib Because of my unique environment I have to add /home/afbacher/LFS71/lfs80 to /usr and /lib in those commands. What is it about adding that prefix that causes bzip2 to fail to find libbz2.so.1.0 in my environment, when it apparently can find that library in the normal LFS-assumed environment without using export LD_LIBRARY_PATH=... ? I must not be understanding something basic about Linux search paths. Linux looks in /lib and /usr/lib by default. LD_LIBRARY_PATH just says to add that to the search path. /etc/ld.so.conf can also add directories to be searched. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

So looking in /lib and /usr/lib is hardwired? I take it that in normal circumstances, /etc/ld.so.conf is sort of a universal holding file for search paths. Is there some kind of documentation that explains all this? I've looked around but have not found anything that really gets into such details. Again, thanks for your help!
