Trouble installing htk: /usr/bin/ld: cannot find -lX11

**Robing Goodfellow** · July 1st, 2012

Greetings!

I'm trying to install the HTK 3.4.1. I'm running Precise on a 64 bit HP G62.

I've downloaded and extracted to tarball to my Home directory, ran ./configure, no problems, ran make all and got and error stating "/usr/bin/ld: cannot fond -lX11"

here's the terminal output from the make all command:

Code:

~/htk$ make all

I looked in my /usr/bin directory, not ld, but there is an X11 file in there. Is this a path issue? I'm a little lost.

I tried the following and it worked for me:

Code:

sudo ln -s /usr/lib/i386-linux-gnu/libX11.so.6.3.0 /usr/lib32/libX11.so

**Robing Goodfellow** · July 3rd, 2012

Awesome, worked like a champ, thanks so very much! Now, since I'm still relatively new to this (shell commands and scripts), can you tell me what it all means?

regards, Richard

Hi,
I am trying to install HTK-3.4.1 on ubuntu and having a similar error like above and I have even tried creating symbolic link but it says files exists.
Can someone help me?
