If you are trying to compile YACReader, you need to donwload de source code of 7zip (Windows) or p7zip (Linux/MacOSX).
If you are trying to compile YACReader with a 7zip decompression backend, you need to download de source code of 7zip (Windows) or p7zip (Linux/MacOSX).
Please, extract it and rename the folder to lib7zip (Windows) or libp7zip (Linux/MacOSX), then copy it to $YACREADER_SRC/compressed_archive/ (this
folder). If you are using a 64 bit Linux-System, please apply libp7zip.patch for successfull compilation or use compileX11.sh.
Please extract it and rename the folder to lib7zip (Windows) or libp7zip (Linux/MacOSX), then copy it to $YACREADER_SRC/compressed_archive/ (this
folder).
YACReader is compiled using 7zip/p7zip 9.20.1
YACReader is compiled using 7zip/p7zip 9.20.1 and will not work with newer versions.
On Linux/Unix this means your YACReader installation will stop working if you update your installation of p7zip to a newer version. If you wish to keep using
p7zip with YACReader, you can copy 7z.so and Codecs/Rar29.so from p7zip 9.20.1 to "/usr/lib/yacreader/". YACReader will then detect these files and use
them instead of the system provided p7zip files which allows you to keep both YACReader and an up to date p7zip installation.
Please keep in mind this is only a workaround that is provided for backwards compatibility and not intended as a long time solution.
It is recommended that you switch to unarr as a decompression backend instead (see README.txt in compressed_archive/unarr).

To use unarr as a decompression engine when building YACReader, download https://github.com/zeniko/unarr/archive/master.zip and extract it in this folder.
This will build unarr as a part of YACReader (static build).
If you're on a Linux/Unix system and prefer to use unarr as a shared library, have a look at https://github.com/selmf/unarr/
This fork of unarr includes a CMake based build system that allows you to build and install unarr as a shared library. YACReader will detect and use
the installed library at build time if it is installed.
