I was trying to build HTK using Ubuntu 11.04.
These are the commands I used:
sudo ./configure make all
I immediately get the error:
X11/Xlib.h: No such file or directory
So when I try to install
libX11-dev by using:
sudo apt-get install libX11-dev
I got the following error:
Unable to locate package libX11-dev
I'd appreciate some help on this.
