LinuxQuestions.org - [SOLVED] Samba 4 alpha14 compilation error on Slackware64-13.1

Hello everyone,
I'm trying to compile Samba 4 on Slackware64. I used tarbal version alpha14, but
make fails before end of the process saying:

Code:

make: *** [all] Error 1

Has anoyone here similar trouble? Or can you determine what I'm doing wrong from the error message?
I think I'm missing some libs or so, but I cannot find any help other than for Debian, and I'm Slackware guy :-)

Complete configure and make output can be foung here:
