Hello Pedra Fonseca, ./configure --build=i686-pc-linux-gnu --target=i686-pc-linux-gnu "CFLAGS=-m32" "CPPFLAGS=-m32" "LDFLAGS=-m32" I use the above command to build ltp for 32-bit architecture on 64-bit machine. Once you do run this, you can check the CFLAGS, CPPFLAGS, LDFALGS being set in config.status file. --target flag is to set target environment if it is different from build environment. http://stackoverflow.com/questions/5139403/whats-the-difference-of-configure-option-build-host-and-target In fedora-64 bit, to build a 32-bit binary you need following packages sudo yum install glibc-devel.i686 libgcc.i686 May be in Ubuntu, you may need these packages or similar kind. If not installed gcc will throw some error. Let me know if you still find problem.
