This problem should be obvious to everyone who installs gcc-3.4.1, since you have to select how the standard library will be compiled.
I just installed it on two machines by building it from source and didn't need to make any such explicit selection. I wonder what I ended up with by default?
As I said, I build GCC from source very frequently, with various non-default configurations, but have never changed the thread model from the default. You can find out which model was used from the output of "gcc -v". It should include a line saying "Thread model: xxx" The choices if you *do* make an explicit choice, are here: http://gcc.gnu.org/install/configure.html Not all thread models work on all targets. Martin's mail was misleading, a library with posix thread model supports both multithreaded code using pthreads, and single-threaded code. (If that wasn't the case there'd be no problem in the first place). Seems like there are a lot of misunderstandings surrounding this issue. Would it help if I summarised the problem, what's being done, and the workaround? jon -- Rules of Optimization: Rule 1: Don't do it. Rule 2 (for experts only): Don't do it yet. - M.A. Jackson
