Hi Eddy, > What is your platform? Darwin >It is also (apparently) an issue on either Ubunto or Gentoo (sorry, can't remember which, so please feel free to correct me...), so I know it is not unique to openSuSE, which would imply something more fundamental... Regardless, it's not a GCC issue. Pthreads are not supplied/supported by GCC. I don't say this to chastize. I say it to help you find the answers you seek on a more suited forum that will have the expertise. HTH, --Eljay
