Hello!

I spent hours on the internet to find an easy manual that tell me how I can compile the libaacs source myself for windows operating system but couldn't find anything suitable.

Finally I started to follow the general vlc compile instructions here: https://wiki.videolan.org/Win32Compile/

installed ubuntu 14.4lts 32 bit in virtualbox
installed ssh server
started to connect with putty because it's more convenient
installed the mingw-w64 toolchain as requested on the wiki page
saved the script to 'enforce static compilation' in a sh-file and executed it
installed all 'development tools' listed on the wiki page
decided that >i686-w64-mingw32< is the correct host-triplet in my case
copied the source code of libaacs-0.8.1 with winscp in a subfolder on my virtual ubuntu
skipped the part about 'prepare 3rd party libraries' because there's no folder 'contrib' in the source directory of libaacs-0.8.1
executed the steps listed unter 'Configuring the build'
>> bootstrap
>> configure (but skipped the PKG_CONFIG_LIBDIR section because I still don't have a 'contrib' folder)
(installed bison and libgcrypt because configure failed without them)
and finally I tried to execute make but it fails immediatly

The result of the 'make' execution is:

Code: Select all

root@test-VirtualBox:/home/test/libaacs-0.8.1# make
make  all-am
make[1]: Verzeichnis »/home/test/libaacs-0.8.1« wird betreten
  CC       src/libaacs/aacs.lo
src/libaacs/aacs.c:44:20: fatal error: gcrypt.h: No such file or directory
 #include <gcrypt.h>
                    ^
compilation terminated.
make[1]: *** [src/libaacs/aacs.lo] Fehler 1
make[1]: Verzeichnis »/home/test/libaacs-0.8.1« wird verlassen
make: *** [all] Fehler 2

I guess the problem might be related to a warning I get during the configure-step:

For both libgcrypt and gpg I get the warning that they do not match (or support) to specified host 'i686-w64-mingw32' - is this my problem? And in case it is - how can I resolve it?

Thanks for your help! Unfortunately I'm quite a newbie when it comes to compiling something

Yes, that is your problem.

Thanks for your answer - but how can I solve my problem?

Other people also managed to compile libaacs for windows - so there has to be a way to do this.

In case you think cross-compiling in linux for windows is not the right way I'd be grateful if you could lead me into the right direction...

Thanks in advance!

I would check the configure help. You are probably missing some parameter here.

Back from my vacation - and finally I managed to compile libaacs

Basically libaacs needs libgcrypt, and libgcrypt needs gpg-error - but the special thing here is that it is necessary to also use a cross-compiled build of the latest 2 packages! So my first try to simply make 'apt-get install libgcrypt...' has been totally wrong.

So I had to build them myself with this commands:

Code: Select all

mkdir ~/compile
cd ~/compile

curl ftp://ftp.gnupg.org/gcrypt/libgpg-error/libgpg-error-1.19.tar.bz2 | tar xvj
cd libgpg-error-1.19/
./autogen.sh --build-w32
make
make install
cd ..

curl ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.3.tar.bz2 | tar xvj
cd libgcrypt-1.6.3/
./autogen.sh --build-w32
make
make install
cd ..

Now the files are all in the folder '/root/w32root'

And finally it's possible to compile libaacs and use the files in this folder:

Code: Select all

curl ftp://ftp.videolan.org/pub/videolan/libaacs/0.8.1/libaacs-0.8.1.tar.bz2 | tar xvj
cd libaacs-0.8.1/
./configure --host=i686-w64-mingw32 --with-libgcrypt-prefix=/root/w32root --with-gpg-error-prefix=/root/w32root
make
make install
cd ..

the last part is to copy all necessary files in one folder to make it easier to transfer them to windows:

Code: Select all

mkdir win_libaacs
cd win_libaacs/
cp ~/compile/libaacs-0.8.1/parser_test.exe ./
cp /usr/local/bin/aacs_info.exe ./
cp /usr/local/bin/libaacs-0.dll ./
cp /root/w32root/bin/libgcrypt-20.dll ./
cp /root/w32root/bin/libgpg-error-0.dll ./

Hope this helps other users too

In the end the build process for all packages takes less than 5 minutes... it's only a matter of knowing what to do

Tried to compile the x64 binaries for windows and finally managed to succeed

Install the x64 tools as noted on the wiki page (in addition to the other tools installed before)

Code: Select all

apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 mingw-w64-tools

I also learned it's a lot easier if you create a new directory for the compile-process:

Code: Select all

mkdir /libaacscompile
mkdir /libaacscompile/install64
cd /libaacscompile

Compile libgpg-error:

Code: Select all

curl ftp://ftp.gnupg.org/gcrypt/libgpg-error/libgpg-error-1.20.tar.bz2 | tar xvj
cd libgpg-error-1.20/
./autogen.sh --build-w64 --prefix=/libaacscompile/install64/
make
make install
cd ..

Compile libgcrypt

Code: Select all

curl ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.6.4.tar.bz2 | tar xvj
cd libgcrypt-1.6.4/
apply this patch here: [url]http://lists.freedesktop.org/archives/gstreamer-commits/2014-February/077093.html[/url]
>> this basically means to edit the file random/rndhw.c, search for '&& defined(__LP64__)' and insert '//' in front of it - this has to be done 2 times in the file
./configure --host=x86_64-w64-mingw32 --disable-asm --with-gpg-error-prefix=/libaacscompile/install64 --prefix=/libaacscompile/install64
make
make install
cd ..

Compile Libaacs

Code: Select all

curl ftp://ftp.videolan.org/pub/videolan/libaacs/0.8.1/libaacs-0.8.1.tar.bz2 | tar xvj
cd libaacs-0.8.1/
./configure --host=x86_64-w64-mingw32 --with-libgcrypt-prefix=/libaacscompile/install64 --with-gpg-error-prefix=/libaacscompile/install64 --prefix=/libaacscompile/install64
make
make install
cd ..

You can find all created files in the directory /libaacscompile/install64/bin, basically you need the following:

libaacs-0.dll
libgcrypt-20.dll
libgpg-error6-0.dll
aacs_info.exe (is not directly necessary, but with this file you can test the compiled library without any additional tools)

Posted: **04 Nov 2015 21:00**

Learned a few things in the last couple of days:

it's more convenient to set the directory for the final files as environment variable and simply use the environment-variable when specifying the prefix-values

export BUILDDIR=/libaacscompile/install_x64

when compiling libgcrypt it's not necessary to include all supported encryption standards - so the following configure command includes everything necessary for libaacs and creates a smaller dll-file:

./configure --host=i686-w64-mingw32 --prefix=$BUILDDIR/ --with-gpg-error-prefix=$BUILDDIR --enable-ciphers=aes --enable-pubkey-ciphers=ecc --enable-digests=sha1 --enable-random=w32 --enable-kdfs=pkdf2 --disable-padlock-support --enable-threads=windows

And for 64 bit builds it's not necessary to edit the rndhw.c file any longer:

./configure --host=x86_64-w64-mingw32 --prefix=$BUILDDIR/ --with-gpg-error-prefix=$BUILDDIR/ --enable-ciphers=aes --enable-pubkey-ciphers=ecc --enable-digests=sha1 --enable-random=w32 --enable-kdfs=pkdf2 --disable-padlock-support --enable-threads=windows --disable-asm

Finally it's a good idea to 'strip' the compiled files to remove debug information not necessary for the common user:

strip -s /libaacscompile/install_x64/bin/*

This last step reduces the filesize a lot! (from 5MB to 500KB)
