hello
all
i am working on a project in c++. i am working on the kdevelop having gnu compiler . i want to incorporate exception handling in my program like catch and try but i am getting error at the compilation end . should i have to do some chnages in the kdevelop editor options to get the catch enabled .
waiting for ur reply

I don't think that's necesary, i gues it's just a bug in your code.
Post here your code, maybe that i can help.

hello i am adding the source code having the try and catch statement . i get run time error in the statement having catch and the error is "err" is unknown function

else

Im not really a c++ guru, but if you can comment things and recompile it to check where the problem is.And ofcourse use a debugger(add -g).

hi
how to use the -g command and can u tell me the syntax by taking the example as i am not working on the prompt but on kdevelop .
can u also tell me or send me a make file example and how to write makefile to link different libraries

I think in the linker options, just add -g to it
And im not really an expert of make files, i just use the g++ compiler to compile my source codes without make files.
