C.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 GDB 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 GDB source directory (gdb-12.0.50.20211026-git
, for version 12.0.50.20211026-git).
