Hi, I'm trying to build 4.2.2 on a redhat x86_64 system. I get the following during the configuration process that happens during make bootstrap: ... configuring stage 1 in ./bfd loading cache ./config.cache checking host system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized checking target system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized checking build system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized ... And a little later: checking whether ln -s works... yes ltconfig: you must specify a host type if you use `--no-verify' Try `ltconfig --help' for more information. configure: error: libtool configure failed Here's the configure line (same behavior without the variables defined) $ LIBRARY_PATH=/network/lib64 C_INCLUDE_PATH=/network/include /home/acbell/gcc/gcc-4.2.2/configure --prefix=/home/acbell/gcc/bindir Here's the build command: $ LIBRARY_PATH=/network/lib64 C_INCLUDE_PATH=/network/include make bootstrap Any ideas appreciated. -- Andrew Bell andrew.bell.ia@xxxxxxxxx
