Hi, I have just done a fresh install of Mandrake 8.0 after having used 7.2 with no problems for some time. I am trying to install two different commercial symbolic math packages, Macsyma Pro 2.4 and Maple V. Both packages seem to install fine, but the executables they install are not recognized by the system. I can list them, e.g. ls -l for Maple gives: # ls -l mapleTTY -rwxrwxr-x 1 alias 24 669660 Jan 11 1998 mapleTTY* but trying to execute it gives the following: # ./mapleTTY bash: ./mapleTTY: No such file or directory The same problem occurs for Macsyma. Both packages installed and ran fine under 7.2. Anybody got any ideas? Thanks for any help Will
