Throw exception from shared object.   
Hello,

I try to throw a C++ exception from a function located in a shared lib and catch it from my main thread.
But the only thing I get is a "core dumped" ...

my compiler version : 3.3.1 and my QNX core version :  6.3.0

Did anyone do  the same stuff ?

Thanks

RE: Throw exception from shared object.   
To this all the time and works fine, but I`m not using 6.3.0.

Did you add the compiler option to support exception,when building the shared lib and program?

Thanks you Mario for your answer.
I don't know what kind of options are needed to use C++ exceptions in a shared lib.
I've tried -fexceptions but it seems that options is just need for C functions to work  with mixed C++.

Re: RE: Throw exception from shared object.   
It seems  the problem was : I linked my shared lib with qcc and not with QCC.

Some of my file are c file and other are c++ files. I always use qcc and it selects the good compiler with the extension
 of the files (c or cpp ). 
 
But the problem appears  when I make the dynamic lib with the object files collection.
    
before (I get Abort and core dumped ) :

qcc -o mylib.so obj1.o obj2.o ....

now (it works fine):

QCC -o mylib.so obj1 obj2.o 

Voilà.
