Smart token debug gdb on pcscd

[vipint99]

Hi Ludovic,
I am trying to make a iKey1000 (safenet->now Gemalto) usb token to respond to API. I have its own IFD library loaded ( as module) and all looks fine on PCSCD foreground debug messages.
When I try to open this device it fails (create context is ok) , It is using pcsc-lite library but not supporting standard CCID.
Now I want to debug this once it is detected by udev_hotplug. how to set gdb to put breakpoints to check what this driver is doing ( even in assembly code). Please help me setup debug with pcscd since it is not crashing and backtrace is not available.
I am using PCSC ver 1.8.8 source and then compiled on Centos7 32bit , since device drivers are of 32 bit version.
Please help !!

This is not a PCSC issue.
You can find lots of gdb documentation on the Internet.

Thanks Ludovic, I am searching and learning from internet. Regards Vipin
