Hi,
Can any one explain me how to correct the purify reported errors and warning( mem leaks), with simple examples.

Purify would clearly say you the function call sequence which resulted with every leak.
You have to start looking at the sequence and start clearing the error.
If you need something else post again

Thanks for your response
I tried with simple program simple.cpp
#include<iostre am.h>
int main() {
char *str = new char[25];
" Testing purify ";
cout << " str is " << str << endl ;
delete[] str ;

return 0;
}

commands:
compiling -> purify g++ -g -gstabs simple.cpp
executing-> ./a.out

But purify giving memory leaks, even i added delete statement.
Please correct the above program to make memory leaks zero.

Thanks

I have ran purify separately and calling the executable from purify.
I think what u are trying is to compile the code with purify instrumentation .

Try running the executable from purify and check whether u are getting any leaks

I am sorry, can we call executable from purify?
U mean compile without purify
g++ -g -gstabs simple.cpp
then invoke the executable from purify.
purify <may_some_optio ns> a.out

I searched in net for long time, no where found that we can invoke exe from purify.
Please explain me with simple program(wat i written), with commands also.

Thanks

I have used Purify on windows some time back.
As u start purify u will get a GUI in which you can call the executable.
Try to read the Purify user guide for this.
