Debugging with GDB (September 2007)

330 Debugging with GDB
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-gdb-199991101’, for
version gdb-199991101).
A.3 configure options
Here is a summary of the configure options and arguments that are most often useful
for building GDB. configure also has several other options not listed here. See Info file
‘configure.info’, node ‘What Configure Does’, for a full explanation of configure.
configure [--help]
[--prefix=dir ]
[--exec-prefix=dir ]
[--srcdir=dirname ]
[--norecursion] [--rm]
[--target=target ]
host
You may introduce options with a single ‘-’ rather than ‘--’ if you prefer; but you may
abbreviate option names if you use ‘--’.
--help Display a quick summary of how to invoke configure.
--prefix=dir
Configure the source to install programs and files under directory ‘dir’.
--exec-prefix=dir
Configure the source to install programs under directory ‘dir’.
--srcdir=dirname
Warning: using this option requires gnu make, or another make that imple-
ments the VPATH feature.
Use this option to make configurations in directories separate from the GDB
source directories. Among other things, you can use this to build (or maintain)
several configurations simultaneously, in separate directories. configure writes
configuration specific files in the current directory, but arranges for them to use
the source in the directory dirname. configure creates directories under the
working directory in parallel to the source directories below dirname.
