Are you building a system from scratch or moving apps from a 32-bit system to a 64-bit system? If the latter and you are staying on, for example, SLES8 then your apps should work. There is a 32-bit compatability (or 64-bit toleration) layer of code in the kernel as well as the 32-bit libs living in /usr/lib and /lib. /usr/lib64 and /lib64 contain the 64-bit stuff.
If you are building from scratch then you can build the nuc. libs etc. on a 32-bit s390 system with a cross-compiler and then boot the resulting kernel in a virtual machine. Neale -----Original Message----- Hello, please can you help me to understand what I have to do coming from a s390 system to get to a s390x system ? ) Is crosscompile with target s390x working on s390 or will I have to crosscompile on x86 ? ) What will I have to do for compatibility with existing s390 programs (compat libraries, ...) ) How would I have to build such libraries, ... ? Please excuse my minimum knowledge in this area. Any help would be greatly appreciated. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
