__kernel_vsyscall ()

I'm trying to compile a program called varkon, but after I chose an option from the main screen it gives me a segfault. The code is to long for me to go through it all, so I tried using gdb.
This was the output:

Reading symbols from /home/oliverj/Downloads/varkon/bin/xvarkon...(no debugging symbols found)...done.
[New Thread 25257]

#0  0x0085e422 in __kernel_vsyscall ()

I don't see how this helps me find the error.

It doesn't. If you compiled with debugging support (-ggdb) it'd probably give you a lot more.

I tryed, but it still gave me the same message.

What exactly did you try?

I tried adding ggdb to the CFLAGS variable, but when I tryed to debug it, it was the same as the first time I tried it. :wall:

Make sure the makefile's not stripping the output.
