This directory contains the things used to build the configure
|
||||
scripts. The file present here are the following:
|
||||
|
||||
makefile a simple makefile to build configure script
|
||||
acconfig.h template file describing src/config.h.in
|
||||
aclocal.m4 local macros for configure.in
|
||||
configure.in the template from which configure is built
|
||||
lib_configure.m4 the template from which lib/configure is built
|
||||
install-sh shell script used when no good install program
|
||||
is found
|
||||
mkinstalldirs shell script used to create installation dirs.
|
||||
stamp-h.in file used by Makefile to check dependencies
|
||||
hack-gcc a shell script to work around possible gcc bugs
|
||||
|
||||
How to use the makefile
|
||||
-----------------------
|
||||
|
||||
When you make a modification to some configure component, just type
|
||||
'make', with the config/ directory being current. This will create
|
||||
configure, lib/configure and config.h.in. Do *not* try to run directly
|
||||
autoconf or autoheader. Note that these scripts require autoconf 2.12
|
||||
or later.
|
||||
|
||||
There is also a target 'clean' which delete backup files, etc.
|
||||
|
||||
Note: please do not rename `makefile' to `Makefile'! This name was
|
||||
chosen in order avoid being excluded from LyX patches...
