I wan't to use ALIZE for speaker recognition and after the instalation there is one of the steps: feature extraction using SPRO or HTK So I downloaded zip file of HTK and using terminal I configured everything, but when entering make all I'm getting this error:

/usr/bin/ld: cannot find -lX11
collect2: error: ld returned 1 exit status
Makefile:56: recipe for target 'HSLab' failed
make[1]: *** [HSLab] Error 1
make[1]: Leaving directory '/home/username/Downloads/htk/HTKTools'
Makefile:108: recipe for target 'htktools' failed
make: *** [htktools] Error 1

what does it mean and how to fix this? I'm looking for answer for hours and can't find anything...

I'm using HTK 3.4.1 stable version and LInux ubuntu 16.10

The error cannot find -lX11 means that ld can't find the libraries for X11 (the X.Org display server). The required libraries can be found in the libx11-dev package which can be installed with:

sudo apt-get install libx11-dev

This should resolve your issue, as long as the libraries install in the LD_LIBRARY_PATH (which is likely if apt-get handles it).

On 64-bit systems, you might need to explicitly state the 32-bit version is required:

sudo apt-get install libx11-dev:i386
