Programming

I have an AIX 64-bit program which uses following from AIX5.3


/usr/lib/libc.a(shr_64.o)
/usr/lib/libpthread.a(shr_xpg5_64.o)
/home/jeet_xp/export/power/usr/lib/libsarpc.a(shr.o)
/unix
/usr/lib/libcrypt.a(shr_64.o)
/usr/lib/libc_r.a(shr_64.o)
/usr/lib/libpthreads.a(shr_xpg5_64.o)
/usr/lib/libiconv.a(shr4_64.o)

when I use a different login I get ldd output as this, which basically takes
libraries of AIX5.1.


/home/jeet_xp/current/export/power/usr/lib/libc.a(shr_64.o)
/home/jeet_xp/current/export/power/usr/lib/libpthread.a(shr_xpg5_64.o)
/home/jeet_xp//export/power/usr/lib/libsarpc.a(shr.o)
/unix
/usr/lib/libcrypt.a(shr_64.o)
/home/jeet_xp/current/export/power/usr/lib/libc_r.a(shr_64.o)
/home/jeet_xp/current/export/power/usr/lib/libpthreads.a(shr_xpg5_64.o)
/home/jeet_xp/current/export/power/usr/lib/libiconv.a(shr4_64.o)



In the first case my program works fine but when in second case with any user using the libraries of older versions the program either traps in pthread or kills my telnet session.
Are there any issues known like this? please help me on this.

The simple answer is you are trying to use the Tardis.

The general rule is that operating systems are backward compatible, not forward compatible.

So a 5.1 program should run on 5.3, but all bets are off for a program compiled on 5.3 to run on 5.1.

Thanks porter for your reply, I understood what you wanted to say. Can you please tell me where can I find what all got changed from one release to other?

Releases, and sub releases!!!!!!! IBM United States, I'm not sure what you are looking for though.

If you have the source, recompile it on a 5.1 box, if not use a 5.3 version machine.
