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

#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
