I am unable to build Haiku cross-tools from the SVN on my 64 bit linux machine. I am using the configuration line: ../configure --use-32bit --build-cross-tools ../../buildtools/ --include-3rdparty --include-gpl-addons --include-patented-code I have all the proper prerequisite software installed, including gcc-multilib and g++-multilib and I have included the --use-32bit option, so I expected it to work, but I am getting the following errors: Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized Unrecognized host system name x86_64-unknown-linux-gnu. How shall I proceed?
