== Compiling Instructions ==

When compiling llink you need to chose if you want to use '''OpenSSL''', '''libdvdread''' and '''libdvdcss'''. Generally we have no reason to use SSL with '''link''' so I will skip this compile time step.

=== Unix, OsX and other native compiles ===

The default should work. 

 # ./configure --without-openssl
 # make
 # file src/llink

The '''file''' command is not necessary, but it shows you where we expect the binary to end up.

However, if you want '''libdvdread''' support, and it can not find it. (Say it installs /opt/local/lib/libdvdread.*)

 # ./configure --without-openssl --with-dvdread=/opt/local/
 # make

If you don't have '''libdvdread''' installed, or do not have permission to do so, you can compile it in a parallel directory and use '''--with-dvdread-tree=''' as shown in the '''cross-compile''' instructions below.

=== Windows ===

Download Visual Devstudio C++ 2008 from (insert microsoft link) and install. Download source package, and load the '''llink.vcproj''' inside "win32/" directory. Change the default project from '''libdirlist''' to '''llink''' and hit compile.

If you want to compile against '''libdvdread''', download this package from (link me) and set the ''environment variable'' '''DVDREAD''' to point to the directory of '''libdvdread'.

For example, '''DVDREAD''' to be "c:/src/libdvdread-0.9.7". You set ''environment variables'' by Properties of My Computer (etc, fill me in).

=== Cross Compile ===

For example when compiling for the PCH A-100, you download the toolchain that applies to your arch. In this case, it installs into '''/usr/local/mips/''' with a '''gcc''' binary named as '''/usr/local/mips/bin/mipsel-linux-gcc'''.

First make sure your PATH is updated so that it can find the executable.

 # export PATH=$PATH:/usr/local/mips/bin/
 # which mipsel-linux-gcc
 /usr/local/mips/bin/mipsel-linux-gcc

Great. If you want to have '''libdvdread''' and '''libdvdcss''' we need to compile those first. If you do not, you can skip this step.

 # cd src/libdvdcss-1.2.2/
 # ./configure --host=mipsel-linux-uclibc --enable-static
 # make
 # file src/.libs/libdvdcss.*
 src/.libs/libdvdcss.a:        current ar archive
 src/.libs/libdvdcss.so.2.0.8: ELF 32-bit LSB shared object, MIPS, version 1 (SYSV), not stripped
 (a few other files, but at least one shows its compiled as MIPS)

 # src/libdvdread-0.9.7/
 # ./configure --host=mipsel-linux-uclibc --with-libdvdcss-includes=/home/lundman/src/libdvdcss-1.2.9/src/ --with-libdvdcss-libs=/home/lundman/src/libdvdcss-1.2.9/src/.libs/
 # make
 # file dvdread/.libs/libdvdread.*
 dvdread/.libs/libdvdread.a:        current ar archive
 dvdread/.libs/libdvdread.so.3.2.1: ELF 32-bit LSB shared object, MIPS, version 1 (SYSV), not stripped

Note that we have to use the full path '''/home/lundman/src/''' to get to the '''libdvdcss-1.2.9/src''' includes. You should change the first part. 

'''Compiling llink'''. Now it is time to compile '''llink''' itself. The version number might change of course.

 # cd src/llink-2.0.7/
 # ./configure --host=mipsel-linux --enable-static --without-openssl --with-dvdread-tree=/home/lundman/src/libdvdread-0.9.7/ --with-dvdcss-tree=/home/lundman/src/libdvdcss-1.2.9/
 # make
 # file src/llink
 src/llink: ELF 32-bit LSB executable, MIPS, version 1 (SYSV), statically linked, not stripped

Naturally, if you do not want '''libdvdread''' go with the shorter line:

  # ./configure --host=mipsel-linux --enable-static --without-openssl
