automake autoconf常用
Here is a diagram showing how the files that can be used in configuration are produced. Programs that are executed are suffixed by ‘*’. Optional files are enclosed in square brackets (‘[]’). autoconf and autoheader also read the installed Autoconf macro files (by reading autoconf.m4).
Files used in preparing a software package for distribution, when using just Autoconf:
your source files --> [autoscan*] --> [configure.scan] --> configure.ac
configure.ac --.
| .------> autoconf* -----> configure
[aclocal.m4] --+---+
| `-----> [autoheader*] --> [config.h.in]
[acsite.m4] ---'
Makefile.in
Additionally, if you use Automake, the following additional productions come into play:
[acinclude.m4] --.
|
[local macros] --+--> aclocal* --> aclocal.m4
|
configure.ac ----'
configure.ac --.
+--> automake* --> Makefile.in
Makefile.am ---'
Files used in configuring a software package:
.-------------> [config.cache]
configure* ------------+-------------> config.log
|
[config.h.in] -. v .-> [config.h] -.
+--> config.status* -+ +--> make*
Makefile.in ---' `-> Makefile ---'
