1.2. How to install fcron

1.2.1. Compilation requirements

• A C compiler (e.g. gcc)

• (optional) readline development library (e.g. libreadline-dev)

• (optional) PAM development library (e.g. libpam0g-dev)

• (optional) SE Linux development library (e.g. libselinux1-dev)

• (optional) Linux audit development library (e.g. libaudit-dev)

• If compiling from git checkout (rather than a tarball), then no generated file will be included out of the box, so you will need more tools to generate them. In particular the ./configure script and the documentation will be generated from the sources.

  • git

  • autoconf

  • docbook

  • docbook-xsl

  • docbook-xml

  • docbook-util

  • manpages-dev

1.2.2. Compilation and installation instructions

• uncompress the archive:

  bash$ tar -xzf fcron-X.Y.Z.src.tar.gz

• cd to the archive directory

  bash$ cd fcron-X.Y.Z

• run the configure script:

  bash$./configure

  • If you can't see a ./configure, then you probably checked out the files from git, in which case you need to run autoconf to generate the configure script.

  • If using PAM, beware that by default the PAM configuration will be installed in /usr/local/etc/. That most likely mean that your system won't use this config, and may ask you to type your password everytime you start fcrontab or fcrondyn.

    The simplest way to avoid this is to instruct configure to use /etc instead with:

    bash$ ./configure --sysconfdir=/etc

  • You may also want to change the place where fcron will be installed: you can use the configure 's option --prefix to do that. For instance:

    bash$ ./configure --prefix=/usr --sysconfdir=/etc

    (default is prefix=/usr/local and sysconfdir=${prefix}/etc).

  • To disable the use of PAM, SE Linux or fcrondyn, use configure's option --with-pam=no, --with-selinux=no and/or --with-fcrondyn=no.

  • The command make install asks you by default some questions you have to answer. To avoid that (which can be useful for automatic installers), you can use the ./configure's option --with-answer-all and/or --with-boot-install (see "./configure --help" for more details).

  • To debug fcron, you should use configure 's option --with-debug.

  • You can get info on the others configure 's options by running "./configure --help".

  Warning

  The configure script may not define a correct directory for the man pages and the documentation on some systems. You may check the values defined by configure and if necessary force a value by the options --mandir and -with-docdir (see the help by running "./configure --help"). If you get older fcron's man-pages with man command after having upgraded, it's probably because fcron has changed its default man directory: you should remove manually the outdated man-pages. The Makefile has been designed for GNU make. Some other version of make may fail to use it.

• (optional) check the file config.h, and change it if necessary (the configurable part is on the top of the file and clearly delimited).

• compile:

  bash$ make

• then install binaries as root:

  bash$ su root

  bash# make install

You can now run fcron and fcrontab.
