compiled program may not run on PA 1.x system.

[Rainer von Bongartz]

When I compile programs with cc on my K460 I always
get a warning

/usr/ccs/bin/ld: (Warning) At least one PA 2.0 object file (h.o) was detected. The linked output may not run on a PA 1.x system.

transfering my compiled binary to a K200 server ( PA 1.x )
I get the error message:

Execute permission denied, though the x-bit is set correctly.

Why can't I run programs compiled on K460 on K200 ???

When you compile your program add either of 2 options;

1. +DAportable This means your binary will now run on and HP-UX version/cpu.

2. +DA1.1 Now it will run on older 1.1 CPU's servers.

Hi!

You just have to re-compile your program on the PA 1.1 machine, because a system library is not compatible to older systems. It's not a bug, it's a feature ;-)). You will get this warning message everytime your program contains functions with system calls for ipc handling, tcp functions or such stuff.

Hi,

You compile on a 64bits system (K460 : PA800 64 bits) with PA2.0 libs (64bits also). Your
binary can't works on 32bits system (K200 :
PA7200 32 bits).

You can verify if your systems are 32 or 64
bits using "getconf KERNEL_BITS". When you
compile on a 64 bits system it produce
64bits binaries (see aCC man page
+DArchitecture option). You have to solutions :

1) 2 compilations : 32 or 64 bits
2) Compile in 32bits (if the K460 can
use 32 AND 64 bits, use "getconf HW_32_64_CAPABLE"
to verify if it's possible. You can specify to
aCC to compile a portable binary : -DAportable
