[Solaris 2.8 && Sun Studio 10]

Hi,

I have a very simple library that wraps a Timer class and a test
program linked to it.

First of all, I compile the library and the main without the KPIC flag.
Then, I execute the program and, while it's running, I add some dummy
sentence to the library and recompile it. Nothing happens to the binary
running. It keep unaware of changes in the library and keeps running.

Now, I recompile everything with KPIC and try to make the same test.
Just when the library has been recompiled, execution is broken by a
core dump.

You'd say that it has an easy solution: do not use the KPIC but I'm
trying to develop my program in 64 bits and I'm forced - as far as I
know - to compile using the KPIC flag.

Any idea of how to make it work? I can't assume to stop all my programs
after any change in the library.

Thanks in advance
Jorge Ortiz

C doesn't have classes; are you using C++?

It looks like your problem isn't really related to the C programming
language; rather, it's specific to Solaris. You'll get much better
help in comp.unix.solaris.
