HTK fator error

1. If you try to install HTK on 64 bits machine, you might get some fatale error like “/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory”. Because by default, it try to compile it on 32 bits machine. So you need to install gcc and g++ for 32 bits machine.
On fedora:
yum install glibc-devel.i686
On Ubuntu: install the following pakages
g++-multilib
gcc-multilib


2. Personally, when i do “make all” on my machine (fedora 15), I get another fatal error
“HGraf.c:73:77: fatal error: X11/Xlib.h: No such file or directory”.

So I need to install “libX11-devel” by by doing

“yum install libX11-devel”.
