But if you turned off multi threading in Pegasus, you would create and ensure the very condition you are concerned about avoiding. You would cause a single threaded library to be linked with multi threaded ones. The only safe solution is to make sure Pegasus is multi treaded, so that you avoid the possibility of a single threaded library being linked to a multi threaded one. There is no risk in a multi threaded library linking to a single threaded one because a single threaded library gets multiple copies. Only the other way around is risky. There is only one copy of a multi threaded library, and you do not want single threaded libraries linking because then more than one could end up linking at the same time.

Hence I was trying to to build openpegasus libs as single threaded. I see libpegcommon uses pthread library. I would like to know if there is way to turnoff the multithreading.
