Thanks. This work.
But I don't understand why. I have 2 debian machine and install the same program on them.
First:
dpkg -l xlibs-dev
ii  xlibs-dev      4.1.0-17 
dpkg -l libc6
ii  libc6          2.2.5-14
Second:
dpkg -l xlibs-dev
ii  xlibs-dev      4.2.1-4
dpkg -l libc6
ii  libc6          2.3.1-9

On first computer programme build without problem but on second I have mistake with libX11 and  pthread.
Thanks.
