Manuals

Tutorials

http://www.lrde.epita.fr/~adl/autotools.html (very nice set of slides)

Libraries

includes (for the include directory): include_HEADERS = ...
library: static lib_LIBRARIES = library.a or dynamic lib_LTLIBRARIES = library.la
sources (internal C data structures and C++ template classes): library_X_SOURCES = library.h ..., where X = a or la

Example

Configured headers

Configured headers (created from *.h.in) must not be included into the package, that is include_HEADERS or *_SOURCES

nodist_include_HEADERS = *.h for the configured headers as includes
nodist_*_SOURCES = *.h or BUILT_SOURCES = *.h for the configured headers as sources

Example

Extra files

To add extra files into package, use EXTRA_DIST = *.

Example

Conditional building

http://www.gnu.org/software/hello/manual/automake/Conditionals.html
In the source code, use macros

#ifdef SYMBOL
...
#endif

MPI support

Define MPI compilers/linkers in configure.ac

AC_PROG_CC([mpicc])
AC_PROG_CXX([mpic++ mpicxx])

C/C++ support

To check C++ features, switch to C++ language in configure.ac

AC_LANG_PUSH(C++)
AC_CHECK_HEADER([header.hpp])
AC_LANG_POP(C++)

To link C code with C++ libraries, add a non-existent C++ file dummy.cpp to sources in Makefile.am

bin_PROGRAMS = program
program_SOURCES = program.c
nodist_EXTRA_program_SOURCES = dummy.cpp
program_LDADD = cpplibrary.a

Script for downloading & installing recent versions (in March 2010) of m4, libtool, autoconf, automake
