# libp11 Installation
The following instructions only apply to the [release tarballs.](

## Unix Build

Install the OpenSSL development package.  On Debian/Ubuntu use:

  sudo apt-get install libssl-dev

Build and install libp11:

  ./configure && make && sudo make install

## Windows Build

Download and install OpenSSL, for example the Windows builds available here:


### MSVC

To build libp11, start a Visual Studio Command Prompt and use:

  nmake -f Makefile.mak

In case your OpenSSL is installed in a different directory, use:

  nmake -f Makefile.mak OPENSSL_DIR=\your\openssl\directory

For x64 bit builds, make sure you opened the Native x64 VS Command Prompt and run:

  nmake /f Makefile.mak OPENSSL_DIR=c:\OpenSSL-Win64 BUILD_FOR=WIN64

If any of your builds fail for any reason, ensure you clean the src directory of obj files before re-making.

### MSYS2

To build libp11, download and install msys2-i686-*.exe from

then start a MSYS2 MSYS console from the Start menu and use:

  pacman -S git pkg-config libtool autoconf automake make gcc openssl-devel

  git clone

  cd libp11

  autoreconf -fi

  ./configure --prefix=/usr/local

  make && make install

### Cygwin

As above, assuming that you have mentioned packages already installed.

### MinGW / MSYS

To build libp11, download and install mingw-get-setup.exe from

I'm assuming that you have selected all necessary MinGW and MSYS packages during install

(useful hint - after clicking at checkbox press key I).

You also need to install pkg-config or pkg-config-lite and update autoconf and openssl.

You need to configure OpenSSL to replace very old mingw's version like this:

  ./configure --prefix=/mingw threads shared mingw

  make depend && make && make install

Then download and unpack libp11, in its directory use:

  libtoolize --force

  aclocal -I m4 --install


  automake --force-missing --add-missing


  ./configure --prefix=/usr/local

  make && make install

### MinGW cross-compile on a Unix host

We assume that OpenSSL is installed in /opt/openssl-mingw64.
Update the paths to match your environment.

  export PKG_CONFIG_PATH=/opt/openssl-mingw64/lib/pkgconfig

  ./configure --host=x86_64-w64-mingw32 --prefix=/opt/libp11-mingw64

  make && sudo make install
