Unlike C code where debugging impose the "-g" compilation flags. This
debugging option only affects Guile code, so using an environment variable
works better since it doesn't impose to recompile Mcron or to edit
"config.scm".
* configure.ac: Remove "--enable-debug" configure option.
* src/mcron/config.scm.in (config-debug): Use MCRON_DEBUG environment variable
to trigger the debug mode at runtime.
* configure.ac: Define "--disable-multi-user" option instead of
"--enable-no-vixie-clobber".
* Makefile.am (install-exec-hook) [MULTI_USER]: Only set crontab setuid bit.
(bin_PROGRAMS): Keep only 'mcron' by default.
(bin_PROGRAMS) [MULTI_USER]: Add 'crontab'
(sbin_PROGRAMS) [MULTI_USER]: Add 'cron'.
(noinst_PROGRAMS) [!MULTI_USER]: Add 'cron' and 'crontab'.
(dist_man_MANS): Move 'crontab.1' and 'cron.8' ...
(extra_mans): here. New variable.
(dist_man_MANS) [MULTI_USER]: Add it.
(all-local) [!MULTI_USER]: New target. Depend on it.
(EXTRA_DIST) [!MULTI_USER]: Distribute it.
(MAINTAINERCLEANFILES): Clean it.
* configure.ac: Use 'GUILE_PKG' and 'GUILE_PROGS'. Remove explicit Guile
version check and check for 'guild'. Honor $GUILE_EFFECTIVE_VERSION in
'moduledir'.
* build-aux/git-version-gen: New script.
* configure.ac (AC_INIT): Use it.
(AC_REQUIRE_AUX_FILE): Distribute it.
* Makefile.am (.version): New target.
(BUILT_SOURCES, EXTRA_DIST): Add it.
(dist-hook): Generate ".tarball-version".
* .gitignore: Update.
Previously PACKAGE_LOAD_PATH was set in config header which wasn't correctly
expanded due to the presence of ${prefix} in ${moduledir}. Let 'make' handle
the expansion.
* Makefile.am (AM_CPPFLAGS): New variable.
(cron_CPPFLAGS, crontab_CPPFLAGS, mcron_CPPFLAGS): Use it.
* configure.ac (PACKAGE_LOAD_PATH): Undefine it.
(AC_CONFIG_HEADER): Remove macro.
* src/mcron.c: Adapt to it.
* configure.ac (AM_INIT_AUTOMAKE): Add more warnings.
* Makefile.am (AM_V_GUILEC, AM_V_GUILEC_, AM_V_GUILEC_0): Rename to ...
(guilec_verbose, guilec_verbose_, guilec_verbose_0): ... these. Make them
more portable. This follows an example from Automake manual.
This allows using 'mcron' before it is installed without hardcoding the
local build environment in the executable.
* build-aux/pre-inst-env.in: New script.
* configure.ac (AC_CONFIG_FILES): Create it.
(AC_CONFIG_HEADER): Add 'config.h'.
(moduledir): New variable.
(PACKAGE_LOAD_PATH): new C preprocessor macro.
* mcron.c: Include "config.h".
(main): Don't overwrite Guile load paths.
(inner_main): Prepend Mcron modules load paths.
* Makefile.am (.scm.go, doc/mcron.1): Use 'pre-inst-env'.
(mcron_CFLAGS): Remove GUILE_LOAD_PATH macro.
(noinst_SCRIPTS): New variable.
* .gitignore: Update.
* configure.ac (AM_SILENT_RULES): Use macro.
* makefile.am (doc/mcron.1): Use $(AM_V_HELP2MAN).
(AM_V_HELP2MAN, AM_V_HELP2MAN_, AM_V_HELP2MAN_): New variables.
* scm/mcron/makefile.am (.scm.go): Use $(AM_V_GUILEC).
(AM_V_GUILEC, AM_V_GUILEC_, AM_V_GUILEC_): New variables.
Remove 'ed' hack to eval content of scm/mcron/main.scm in the C wrapper.
Use proper libguile functions instead.
* scm/mcron/main.scm (mcron main): New module.
(show-version, show-package-information, show-help, main): Remove
extra newline characters in strings.
* mcron.c.template: Rename to ...
* mcron.c: ... this.
(inner_main): Set current module to (mcron main).
* makefile.ed: Delete file.
* configure.ac: Remove check for 'ed'.
* makefile.am: Adjust accordingly.
* .gitignore: Likewise.
