LinuxQuestions.org - compile omxplayer on rpi2 slackware

Since the slackbuid for omxplayer can not be accessed anymore, I decide to compile the omxplayer on my newly installed slackware-current on rpi2. There will come out various compiling error while tweaking the Makefile.include and Makefile.
On the slackware-current installation, you have to revise the /opt/vc/include/interface/vmcs_host/vcgencmd.h to solve #include "vchost_config.h" can not be found problem by adding the correct path like:"#include "interface/vmcs_host/linux/vchost_config.h". Also you need to copy the dbus-arch-deps.h from /usr/lib/dbus-1.0/include to /usr/include/dbus-1.0/dbus. The revised Makefile.include and Makefile is as following:
