I was installing [HTK speech recognition kit] from source. When I gave
make all it is giving following error:
(cd HTKLib && make HTKLib.a) \ || case "" in *k*) fail=yes;; *) exit 1;; esac; make: Entering directory `/home/krishna/htk/HTKLib' gcc -ansi -D_SVID_SOURCE -DOSS_AUDIO -D'ARCH="i686"' -Wall -Wno-switch -g -O2 -I. -DPHNALG -c -o HGraf.o HGraf.c HGraf.c:73:77: fatal error: X11/Xlib.h: No such file or directory compilation terminated. make: *** [HGraf.o] Error 1 make: Leaving directory `/home/krishna/htk/HTKLib' make: *** [HTKLib/HTKLib.a] Error 1
I searched regarding this error [and found that]: I need to install package libX11-devel.
$sudo apt-get install libX11-devel Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libX11-devel
But it seems that the package does not exist.
