Re: pthreads

[Matthew Polder]

You are correct, I am linking statically. I did look in /usr/lib and saw
libpthread.so, so I guess I will need to start building dynamic
libraries (I have successfully avoided it up to this point).

However, before using gcc, I was using Sun's C++ compiler, CC. With this
compiler I was able to link statically and have my threads work. I used
the '-mt' flag in compiling and linking and it took care of everything.
I wonder what library it used.

Since =pthreads is not really documented in the gcc manual, is there
another reference where one can learn these things?

thanks,
matthew
