Why Does my Application Segmentation Fault When Using the pthread Library?

Primary Software: Driver Software>>NI-DAQmx
Primary Software Version: 8.0
Primary Software Fixed Version: N/A
Secondary Software: Driver Software>>NI-DMM, Driver Software>>NI-FGEN, Driver Software>>NI-SCOPE

Problem:
I'm programming in C or C++ in Linux using the pthread library, and my application is experiencing segmentation faults. Are there any suggestions on how to fix this?


Solution:
When using the pthread library on Linux it is recommended to link your application with the gcc -pthread flag instead of linking directly with, for instance, -lpthread. If, after
replacing -lpthread, you still get a segmentation fault, you must explicitly link the dl library (-ldl) as the first library in your list.
