B.4 Specifying Names for Hosts and Targets

The specifications used for hosts and targets in the ‘configure’ script are based on a three-part naming scheme, but some short predefined aliases are also supported. The full naming scheme encodes three pieces of information in the following pattern:

 
architecture-vendor-os

For example, you can use the alias sun4 as a host argument, or as the value for target in a --target=target option. The equivalent full name is ‘sparc-sun-sunos4’.

The ‘configure’ script accompanying No value for GDBN does not provide any query facility to list all supported host and target names or aliases. ‘configure’ calls the Bourne shell script config.sub to map abbreviations to full names; you can read the script, if you wish, or you can use it to test your guesses on abbreviations—for example:

 
% sh config.sub i386-linux
i386-pc-linux-gnu
% sh config.sub alpha-linux
alpha-unknown-linux-gnu
% sh config.sub hp9k700
hppa1.1-hp-hpux
% sh config.sub sun4
sparc-sun-sunos4.1.1
% sh config.sub sun3
m68k-sun-sunos4.1.1
% sh config.sub i986v
Invalid configuration `i986v': machine `i986v' not recognized

config.sub is also distributed in the No value for GDBN source directory (‘gdb-No value for GDBVN’, for version No value for GDBVN).
