App Profiler 2 - error in libprofiling version 1.1   
I tried to switch to the latest libprofiling version 1.1 but i get a linker error.
./libprofiling.so: undefined reference to `__ldd_register_eh'
Any hint how to fix this?

TIA

Re: App Profiler 2 - error in libprofiling version 1.1   
Why it is error from .so? You should link to it statically 
(libprofilingS.a)...
(Error is because libc is old and does not have this method)

AW: App Profiler 2 - error in libprofiling version 1.1   
so which libc is required?
I run it with a 6.3.2
is the libc the reason for why I should use the static shared libS.a?
or has the libS.a to be used all the time?

with the version 1.0 I could use the "normal" .so and link dynamically.

Re: AW: App Profiler 2 - error in libprofiling version 1.1   
Linking statically reduces performance overhead (by couple of jumps at 
each function call).

I don't understand what is the problem with unresolved symbols, this 
code did not change...
You can continue to use 1.0 if it works better for you, until we fix 
this problem (which will happened soon because I am working on this 
library right now)

It is still 6.3.2 libc which is required by it should have 
`__ldd_register_eh' defined...

Re: AW: AW: App Profiler 2 - error in libprofiling version 1.1   
I did a double check.
And what to say ... MEA CULPA
due to the problems caused by the multiple use of the eclipse configuration folder (like with the ptrace import problem)
 - I was using a bad compilation environment.
This is now working.
I guess the -configuration option would be worth to mention a bit stronger

thanks
