Dear GHC, I am going to install ghc-5.02.2 on certain Linux machine to which I have ssh access and permission to install ghc-5.02.2 in my user directory (not a system user). The situation is as follows. It has i386-unknown (Pentium Pro II ...), much of memory and disk. I am not sure, but it looks like it is under RedHat-6.2, glibc-2.1.2. It has ghc-4.04 installed in the system area. But it failed to link Main.o of the program main = putStr "hello\n" Probably, Happy, is not installed. Also I applied certain ghc --make M on my Debian Linux machine with ghc-5.02.2, scp -ed the a.out.zip file to the target machine and unzipped it. And it cannot run there, some library not found, something of this sort. Could the GHC installation experts guide me, please? What is easier in this situation, to install from source or from binary? How to install Happy for the first time? How to find out in a regular way the info about Linux system and libc version? Thank you for the advice, ----------------- Serge Mechveliani mechvel@botik.ru
