My problem is solved it was because of not handling receive request before

> Hi Lars
Many thanks for your answer.
Interestingly sygwin didn't show me any error and warning.
I solved that error but my code have previous problem yet,
I added my edited can-New.cpp
Looking for you
Many thanks

Re: [Canfestival-devel] Help me to run my own can virtual driver
Hi,
I do not have cygwin installed so i am using visual studio, it gave a
error while compiling 'uninitialized local variable 'm1' used'
That should be fixed.
If you did not get a segfault, it is pure luck :)
UNS8 LIBAPI canReceive_driver(CAN_HANDLE fd0, Message *m)
{
Message_ * m1;
int res = reinterpret_cast(fd0)->canReceive_driver(m1);
You might want to turn on a loot of the compiler warnings as it will
help finding bugs.
As soon as you have fixed the bug i can take a new look.
Happy coding!
Best Regards
Lars
