Hello All, I am trying to configure gcc-2.95.3 on HPUX 11.31 (on IA). This is the command i am issuing: ../gcc-2.95.3/configure --prefix=/tmp/GCC/test --with-as=/usr/ccs/bin/as --with-ld=/usr/bin/ld --without-gnu-ld --enable-languages=c,c++ --enable-shared I am getting the following output: Config.guess failed to determine the host type. You need to specify one. Usage: configure [OPTIONS] [HOST] Options: [defaults in brackets] --prefix=MYDIR install into MYDIR [/usr/local] --exec-prefix=MYDIR install host-dependent files into MYDIR [/usr/local] --help print this message [normal config] --build=BUILD configure for building on BUILD [BUILD=HOST] --host=HOST configure for HOST [determined via config.guess] --norecursion configure this directory only [recurse] --program-prefix=FOO prepend FOO to installed program names [""] --program-suffix=FOO append FOO to installed program names [""] --program-transform-name=P transform installed names by sed pattern P [""] --site=SITE configure with site-specific makefile for SITE --srcdir=DIR find the sources in DIR [. or ..] --target=TARGET configure for TARGET [TARGET=HOST] --tmpdir=TMPDIR create temporary files in TMPDIR [/tmp] --nfp configure for software floating point [hard float] --with-FOO, --with-FOO=BAR package FOO is available (parameter BAR) --without-FOO package FOO is NOT available --enable-FOO, --enable-FOO=BAR include feature FOO (parameter BAR) --disable-FOO do not include feature FOO Where HOST and TARGET are something like "sparc-sunos", "mips-sgi-irix5", etc. My Question is 1. Can we build gcc 2.95.3 on HPUX 11.31 IA...? if yes, then 2. How should I specify (format) the host part in the configure command..? Thanks in advance.. -Praveen
