It is not intended to be used as-is, but rather to be +dnl modified to the specific needs of the project. +dnl +dnl Lines prefixed with "dnl" are comments that are automatically +dnl removed by Autoconf/M4, thus they will not appear in the generated +dnl configure script (see the M4 documentation for more information). +dnl Such comments are used in this file to communicate information to +dnl you, the developer. In some cases, the comments contain extra +dnl macros that you might consider including in your configure script. +dnl If you wish to include them, simply remove the "dnl" from the +dnl beginning of the line. +dnl +dnl Lines prefixed with "#" are comments that will appear in the +dnl generated configure script. These comments are thus used to clarify +dnl to the user what is happening in that script +dnl +dnl Wherever pyconfigure-specific macros are used, extra comments are +dnl included to describe the macros. + +dnl###################### +dnl Package Information # +dnl###################### + +dnl---- +dnl Initialize Autoconf with the package metadata +dnl The arguments have been set via the project's PKG-INFO file +dnl and correspond to: +dnl +dnl 1) package name (i.e. foo) +dnl 2) package version (i.e. 1.2) +dnl 3) bug/info/project email address (i.e. bug-foo@gnu.org) +dnl---- +dnl +AC_INIT([mediagoblin], [0.4.0.dev], [cwebber@gnu.org]) + +dnl---- +dnl Load macros from the m4/ directory. If you plan to write new +dnl macros, put them in files in this directory. +dnl---- +dnl +AC_CONFIG_MACRO_DIR([m4]) + + +dnl########################### +dnl Program/command support # +dnl########################### +dnl +dnl In this section, we check for the presence of important commands +dnl and programs. + +dnl--PC_INIT---------------------------------------------------------- +dnl This is the only required macro. Its primary function is to find +dnl a Python interpreter that is compatible with the package and set +dnl the PYTHON variable to hold its path. It can optionally take +dnl arguments to specify minimum and/or maximum versions: +dnl PC_INIT: find an interpreter with a version between 2.0 and 3.3.99 +dnl (in other words, up to and including any possible release +dnl in the 3.3 series) +dnl PC_INIT([MIN_VER], [MAX_VER]): Find an interpreter that is between +dnl the minimum and maximum version. If the min is in the 2.0 +dnl series and the max is in the 3.0 series, non-existent +dnl releases (2.8 & 2.9) will be correctly skipped. +dnl---- +dnl +PC_INIT([2.6], [2.7.99]) + +dnl--PC_PYTHON_PROG_PYTHON_CONFIG------------------------------------- +dnl In order to use some of the other macros, you also need the +dnl python-config command, which will fall subject to the same problem +dnl of python3-config being preferred to python2-config. This macro +dnl will be automatically included if you use on of the macros that +dnl depends on it, so you normally don't have to call it. However, if +dnl you require a specific version, you can do something like the +dnl following example. +dnl---- +dnl +PC_PYTHON_PROG_PYTHON_CONFIG([python2-config]) +if [[ "x$PYTHON_CONFIG" == "x" ]]; then + PC_PYTHON_PROG_PYTHON_CONFIG([$PYTHON-config]) +fi + +dnl---- +dnl With the following set of macros, we implement an option +dnl "--with-virtualenv", which the user can pass to the configure +dnl script in order to install to a Virtualenv (AC_ARG_WITH). If the +dnl option is specified by the user, then we check if the program is +dnl available, checking both for "virtualenv" and "virtualenv2" +dnl (AC_CHECK_PROGS) +dnl---- +dnl +# Support installing to a virtualenv via the --with-virtualenv +# configure flag +AC_ARG_WITH([virtualenv], + [AS_HELP_STRING([--with-virtualenv], [install to a Python virtualenv])], + [], + [with_virtualenv=no]) +AS_IF([test "x$with_virtualenv" != xno], + AC_CHECK_PROGS([VIRTUALENV], [virtualenv virtualenv3 virtualenv2], [no]) + AS_IF([test "x$VIRTUALENV" = xno], + [AC_MSG_FAILURE( + [--with-virtualenv given but virtualenv could not be found])]), + AC_SUBST([VIRTUALENV], [no])) +AC_ARG_VAR([VIRTUALENV_FLAGS], [flags to pass to the virtualenv command]) + +dnl---- +dnl If the program uses sphinx-build to build documentation, uncomment +dnl this to create a SPHINXBUILD variable in the Makefile pointing to +dnl the program. Thus, the user would specify +dnl SPHINXBUILD=/path/to/sphinx-build as an argument to the configure +dnl script. Since building the documentation should be optional, just +dnl print a warning. If the program uses some other documentation +dnl system, you can do something similar with it. +dnl---- +dnl +# Check for sphinx-build +AC_CHECK_PROGS([SPHINXBUILD], [sphinx-build sphinx-build3 sphinx-build2], [no]) +AS_IF([test "x$SPHINXBUILD" = xno], + AC_MSG_WARN(sphinx-build is required to build documentation)) + + +dnl---- +dnl These two are standard Autoconf macros which check for the +dnl presence of some programs that we will use in the Makefile. +dnl---- +dnl +AC_PROG_MKDIR_P +AC_PROG_INSTALL + +# Check for a supported database program +AC_PATH_PROG([SQLITE], [sqlite3]) +AC_PATH_PROG([POSTGRES], [postgres]) +if [[ "x$SQLITE" = "x" && "x$POSTGRES" = "x" ]]; then + AC_MSG_ERROR([SQLite or PostgreSQL is required]) +fi + +dnl--PC_PYTHON_SITE_PACKAGE_DIR--------------------------------------- +dnl This uses PYTHON_SITE_DIR to construct a directory for this +dnl project (ie $PYTHON_SITE_DIR/project_name) and stores it in +dnl pkgpythondir. This value is used by Automake for installing Python +dnl scripts. By default, this begins with $pythondir, unexpanded, to +dnl provide compatibility with GNU Makefile specifications, allowing +dnl the user to change the prefix from the commandline. +dnl---- +dnl +PC_PYTHON_SITE_PACKAGE_DIR + +dnl--PC_PYTHON_EXEC_PACKAGE_DIR---------------------------------------- +dnl Same as PC_PYTHON_SITE_PACKAGE_DIR but for $exec-prefix.
