Thanks Jeff and Vladimir. The problem is gone. But a new one came up.

[Linker error] undefined reference to `pthread_mutex_lock'

I guessed I should include libboost-thread-gcc-1_31 as well. But I only found libboost-thread-gcc-1_31.dll, is there anyway I can get around this? or I am out of luck with windows?

Try adding -mthread to the linker command line (I'm not sure about the spelling, for check the docs). Or add -DBOOST_DISABLE_THREADS to the compiler options and rebuild. This assumes you're using gcc 3.3.

yes, I am using gcc 3.3. Tried both options, it did not work. Checked gcc manual, could not find out a solution. Thanks. George

BTW, it's always a good idea to specify the version of compiler you're using, for gcc it can be obtained with "gcc -v".

HTH, Volodya
