The preferred method for using OpenSC on Unix is to use the pre-packaged versions from operating system vendor or distribution (see [[Linux Distributions]], for example). If the version is older than the current version, first try to convince the vendor to upgrade the packaged version, if that’s not a possibility, OpenSC can be easily built from source on any modern Unix.

Typical Installation

We suggest to install OpenSC into /usr and to put the configuration file into /etc/opensc. The default however would be /usr/local and /usr/local/etc, so you might want to change those. We suggest to configure and compile OpenSC like this:

tar xfvz opensc-*.tar.gz
cd opensc-*
./bootstrap
./configure --prefix=/usr --sysconfdir=/etc/opensc
make
sudo make install

Build Requirements

Installing Requirements on Debian/Ubuntu

sudo apt-get install pcscd libccid libpcsclite-dev libssl-dev libreadline-dev autoconf automake build-essential docbook-xsl xsltproc libtool pkg-config

If the certificates in the card are compressed, you also need zlib:

sudo apt-get install zlib1g-dev

Installing Requirements on Fedora

su -c 'yum install readline-devel openssl-devel libxslt docbook-style-xsl pcsc-lite-devel automake autoconf libtool gcc'

If the certificates in the card are compressed, you also need zlib:

su -c 'yum install zlib-devel'

Build Configuration

OpenSC tries to auto-detect all libraries using the pkg-config system.

If you don’t have pkg-config installed, and don’t want to install it, you can use environment variables to tell configure, how to link with some library:

  • PCSC_CFLAGS and PCSC_LIBS for PCSC-Lite
  • OPENSSL_CFLAGS and OPENSSL_LIBS for OpenSSL
  • OPENPACE_CFLAGS and OPENPACE_LIBS for OpenPACE
  • READLINE_CFLAGS and READLINE_LIBS for GNU Readline

./configure --help will list other useful environment variables.

If some libraries are not installed in typical locations, you need to tell pkg-config where to find the *.pc files. You can do this with the PKG_CONFIG_PATH environment variable, for example:

export PKG_CONFIG_PATH=/usr/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/mystuff/liv/pkgconfig

By default, we are compiling OpenSC with -Wall -Wextra -Wno-unused-parameter -Werror, which causes all compiler warnings to be treated as errors. Use ./configure --disable-strict to disable this behavior.
