# Libtasn1 README -- Introduction information This is GNU Libtasn1, a small ASN.1 library. ## License The GNU Libtasn1 C library (lib/) is released under the GNU Lesser General Public License (LGPL) version 2.1 or later; see [COPYING.LESSERv2](COPYING.LESSERv2). The command line tool (src/), self tests (tests/), examples (examples/), and other auxiliary files, are licensed under the GNU General Public License version 3.0 or later; see [COPYING](COPYING). The manual (doc/) is released under the GNU Free Documentation License. (FDL) version 1.3 or later, see [doc/fdl-1.3.texi](doc/fdl-1.3.texi). Other files are licensed as indicated in each file. There may be exceptions to these general rules, see each file for precise information. For any copyright year range specified as YYYY-ZZZZ in this package note that the range specifies every single year in that closed interval. ## Building the library We require several tools to build the software, including: * [Make](https://www.gnu.org/software/make/) * [Automake](https://www.gnu.org/software/automake/) (use 1.11.3 or later) * [Autoconf](https://www.gnu.org/software/autoconf/) * [Libtool](https://www.gnu.org/software/libtool/) * [Texinfo](https://www.gnu.org/software/texinfo/) * [help2man](http://www.gnu.org/software/help2man/) * [Tar](https://www.gnu.org/software/tar/) * [Gzip](https://www.gnu.org/software/gzip/) * [bison](https://www.gnu.org/software/bison/) * [Texlive & epsf](https://www.tug.org/texlive/) (for PDF manual) * [GTK-DOC](https://www.gtk.org/gtk-doc/) (for API manual) * [Git](https://git-scm.com/) * [libabigail](https://pagure.io/libabigail/) (for abi comparison in make dist) * [Valgrind](https://valgrind.org/) (optional) The required software is typically distributed with your operating system, and the instructions for installing them differ. Here are some hints: Debian/Ubuntu: ``` sudo apt-get install make git autoconf automake libtool bison sudo apt-get install texinfo help2man gtk-doc-tools valgrind abigail-tools ``` PDF manual - Debian <= stretch: ``` sudo apt-get install texlive-generic-recommended texlive texlive-extra-utils ``` PDF manual - Debian >= buster: ``` sudo apt-get install texlive-plain-generic texlive texlive-extra-utils ``` The next step is to run autoreconf, ./configure, etc: ``` $ ./bootstrap ``` Then build the project normally: ``` $ ./configure $ make check ``` Happy hacking! ## Manual The manual is in the `doc/` directory of the release.
