Installing HTK on 64-bit Architectures
09 Apr 2014HTK is an important speech recognition tool maintained and founded by the Cambridge University Engineering Department. Once one registers, downloads the code, and unpacks it, the standard recipe for compiling the source on Linux is
However, on a 64-bit architecture this will fail because of a bug on
line 5507 of configure
we see that the generated Makefiles will set the
call to the C compiler to have the -m32
flag (line 3):

case "$host" in
*x86_64*linux*)
CFLAGS="-m32 -ansi -D_SVID_SOURCE -DOSS_AUDIO -D'ARCH=\"$host_cpu\"' $CFLAGS"
LDFLAGS="-L/usr/X11R6/lib $LDFLAGS"
ARCH=linux

The -m32
flag is meant for an
i386 system since it sets "int", "long",
and pointer types to 32 bits. For x86-64 architectures
we want the -m64
flag so we need to change Line 3 above to
After making this change I was able to compile HTK without any further problems.
This note is for HTK version 3.4.1
and hopefully future versions
will include this bug fix.
