Llink:Compiling

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.

# ./configure --without-openssl 
# make

If you want to build libdvdcss in statically (so there is just one binary, no shared library dependencies)

# cd libdvdcss-1.2.10
# ./configure --enable-static
# make
# cd ../
# cd llink-2.2.0
# ./configure --without-openssl --with-dvdcss-tree=`pwd`/../libdvdcss-1.2.10/
# make

Windows

Download Visual Devstudio C++ 2010 from Microsoft and install.

Download the OpenSSL for Windows dev package. [1] Install it, usually at C:/OpenSSL but you can pick any place.

Setup a new Environment Variable, usually done in "My Computer / Properties / Advanced / Environment Variables". Create a new variable called SSL, and set it to the location of your OpenSSL install. Ie, C:/OpenSSL/.

Download source package, and load the llink.vcproj inside "win32/" directory. Change the default project from libdirlist to llink and hit compile.

All file paths should be relative, but sometimes they are not :(

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 libdvdcss we need to compile that first. If you do not, you can skip this step.

# cd src/libdvdcss-1.2.10/
# ./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)

Note that we have to use the full path /home/lundman/src/ to get to the libdvdcss-1.2.10/src includes.

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

# cd src/llink-2.2.0/
# ./configure --host=mipsel-linux --enable-static --without-openssl  --with-dvdcss-tree=/home/lundman/src/libdvdcss-1.2.10/
# 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 libdvdcss go with the shorter line:

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

Known Compiling Issues

The main binary is linked against libdvdcss if requested, even though it need not be. You can omit "-ldvdcss" on the linking line of llink if it affects you.

On C200, if you compile -static, it will product the error:

../sysdeps/unix/sysv/linux/ia64/getpagesize.c:35: __getpagesize: Assertion `_rtld_global_ro._dl_pagesize != 0' failed.

So don't compile statically on C200.

Some systems get:

: undefined reference to `pthread_mutex_init'

and similar errors, change directory into the undvd directory, and copy'paste the final linking line and add "-lpthread" to it. This will be fixed in future.

On ReadyNAS, it will appear to hang after:

[root] listing '/c/media/' with flags 11

This is actually the 2nd process libdirlist core-dumping, in the call to getpwnam(). If llink is compiled statically. Please drop the -static.
