Hi everyone!!

Im trying to create a spanish acoustic modell following the tutorial.. but i'm having problems building and compiling HTK in Linux (Ubuntu 14.04). Maybe a compatibility problem whit gcc version?? Can anyone help me fixing this?

I appreciate any clue!! Thanksss

**************************************************

HTK is now ready to be built.

Type "make all" to build the HTK libraries
and tools.

Then "make install" to install them.

The tools will be installed in /home/jatipson/bin/htk-3.4/bin

Build notes: Language Modelling tools will be
built. HDecode will not be built. You can build
it manually later by running 'make hdecode
install-hdecode'
