This file contains instructions for developers and advanced users that want to build from version controlled sources.
We require several tools to check out and build the software, including:
- Make http://www.gnu.org/software/make/
- Automake http://www.gnu.org/software/automake/ (use 1.11.3 or later)
- Autoconf http://www.gnu.org/software/autoconf/
- Autogen http://www.gnu.org/software/autogen/ (use 5.16 or later)
- Libtool http://www.gnu.org/software/libtool/
- Gettext http://www.gnu.org/software/gettext/
- Texinfo http://www.gnu.org/software/texinfo/
- Tar http://www.gnu.org/software/tar/
- Gzip http://www.gnu.org/software/gzip/
- Texlive & epsf http://www.tug.org/texlive/ (for PDF manual)
- GTK-DOC http://www.gtk.org/gtk-doc/ (for API manual)
- Git http://git-scm.com/
- Perl http://www.cpan.org/
- Nettle http://www.lysator.liu.se/~nisse/nettle/
- Guile http://www.gnu.org/software/guile/
- p11-kit http://p11-glue.freedesktop.org/p11-kit.html
- gperf http://www.gnu.org/software/gperf/
- libtasn1 http://josefsson.org/libtasn1/ (optional)
- Libidn http://www.gnu.org/software/libidn/ (optional, for internationalization of DNS)
- AWK http://www.gnu.org/software/awk/ (for make dist, pmccabe2html)
- git2cl http://savannah.nongnu.org/projects/git2cl/ (for make dist, ChangeLog)
- bison http://www.gnu.org/software/bison (for datetime parser in certtool)
- libunbound https://unbound.net/ (for DANE support)
- abi-compliance-checker http://ispras.linuxbase.org/index.php/ABI_compliance_checker (for make dist)
The required software is typically distributed with your operating system, and the instructions for installing them differ. Here are some hints:
gNewSense/Debian/Ubuntu:
apt-get install git-core autoconf libtool gettext autopoint
apt-get install guile-2.0-dev libtasn1-6-dev
apt-get install libidn11-dev gawk gperf git2cl
apt-get install libunbound-dev dns-root-data bison
apt-get install automake autogen nettle-dev libp11-kit-dev
apt-get install help2man gtk-doc-tools
apt-get install texinfo texlive texlive-generic-recommended texlive-extra-utils
Sometimes, you may need to install more recent versions of Automake, Nettle, P11-kit and Autogen, which you will need to build from sources.
Dependencies that are used during make check are listed below. Moreover, for basic interoperability testing you may want to install openssl and polarssl.
- Valgrind http://valgrind.org/ (optional)
- Libasan https://gcc.gnu.org// (optional)
- datefudge http://packages.debian.org/datefudge (optional)
- nodejs http://nodejs.org/ (needed for certain test cases)
- softhsm http://www.opendnssec.org/softhsm/ (for testing smart card support)
- dieharder http://www.phy.duke.edu/~rgb/General/dieharder.php (for testing PRNG)
apt-get install valgrind libasan1
apt-get install nodejs softhsm datefudge dieharder
apt-get install libpolarssl-runtime openssl
To download the version controlled sources:
$ git clone git://gitorious.org/gnutls/gnutls.git
$ cd gnutls
$ git submodule update --init
The next step is to run autoreconf (etc) and then ./configure:
$ make bootstrap
When built this way, some developer defaults will be enabled. See cfg.mk for details.
Then build the project normally:
$ make
$ make check
Individual tests that may require additional hardware (e.g., smart cards) are:
$ sh tests/suite/testpkcs11
If you wish to contribute, you may read more about our coding style in doc/README.CODING_STYLE. Note that when contributing code that is not assigned to FSF, you will need to assert that the contribution is in accordance to the "Developer's Certificate of Origin" as found in the file doc/DCO.txt. That can be done by sending a mail with your real name to the gnutls-devel mailing list. Then just make sure that your contributions (patches), contain a "Signed-off-by" line, with your name and e-mail address. To automate the process use "git am -s" to produce patches.
Happy hacking!
