Cross-compile libaacs for Windows (64bit)

For this guide the ubuntu:yakkety Docker image was used.

Install the cross-compile toolchain

apt-get install mingw-w64-tools gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 wget gettext bison flex

Build dependencies

Now we need to build the libaacs dependencies first, those are, as time of writing:

• libgpg-error
• libgcrypt

In this guide I assume we created a folder libaacs:

mkdir /libaacs && cd /libaacs

Of course you can choose any location you want.

libgpg-error

1. Download the source:

   wget https://www.gnupg.org/ftp/gcrypt/libgpg-error/libgpg-error-1.25.tar.bz2

2. Extract the source:

   tar xvfj libgpg-error-1.25.tar.bz2

3. Configure:

   cd libgpg-error-1.25/
   ./configure --host=x86_64-w64-mingw32 --prefix=/libaacs/build-64/
   

4. Build it:

   make
   make install
   cd ..
   

libgcrypt

1. Download the source:

   wget https://www.gnupg.org/ftp/gcrypt/libgcrypt/libgcrypt-1.7.3.tar.bz2

2. Extract the source:

   tar xvfj libgcrypt-1.7.3.tar.bz2

3. Configure it:

   cd libgcrypt-1.7.3/
   ./configure --host=x86_64-w64-mingw32 --with-gpg-error-prefix=/libaacs/build-64 --prefix=/libaacs/build-64
   

4. Build it:

   make
   make install
   cd ..
   

Build libaacs

Now that we have built the dependencies, we can continue building libbluray.

1. First we need to download the source:

   wget ftp://ftp.videolan.org/pub/videolan/libaacs/0.8.1/libaacs-0.8.1.tar.bz2

2. Extract it:

   tar xvfj libaacs-0.8.1.tar.bz2

3. Configure:

   cd libaacs-0.8.1/
   ./configure --host=x86_64-w64-mingw32 --with-gpg-error-prefix=/libaacs/build-64 --with-libgcrypt-prefix=/libaacs/build-64 --prefix=/libaacs/build-64
   

4. Build it:

   make
   make install
   cd ..
   

You will find the build results in /libaacs/build-64/bin

The latest version of libaacs is libaacs-0.9, so you can use the latest version of libaacs when compiling. The older version of dependencies are still usable for libaacs-0.9. Windows Subsystem for Linux (WSL) can also be used to cross compile libaacs (I did this using my WSL).

libgpg-error must be libgpg-error-1.37 at minimum to include commit 7865041c77f4f7005282f10f9b6666b19072fbdf. Otherwise it won't build on systems with gawk (which ./configure seems to prefer).
