Force 64bit compilation?

[Danack]

Hi,

I'm compiling from the ImageMagick-6.8.7-0 source on a Centos 64bit vagrant box, http://developer.nrel.gov/downloads/vag ... 130427.box

It appears that only the 32bit libraries are being built. Is there any way to force the 64bit libraries to be built?

This is the configure line I'm using:

./configure --prefix=/usr/ --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes --disable-openmp

Apologies in advance if this is in the wrong place.
