source code archive missing files

[Michail]

After getting the source code for the 7zip package using apt-get source 7zip, I attempted to compile the 7z.so library:

cd 7zip-23.01+dfsg/CPP/7zip/Bundles/Format7zF
make -f makefile.gcc

make: *** No rule to make target '../../Compress/Rar1Decoder.cpp', needed by '_o/Rar1Decoder.o'. Stop.

I need to compile 7z.so for a few reasons:

1. p7zip-full package uses older v16.02 of the 7zip sources
2. Version 23.01 of 7zip included in the 7zip package made a breaking change in the library and requires Z7_USE_VIRTUAL_DESTRUCTOR_IN_IUNKNOWN flag to be set to be compatible with older headers and programs that load 7z.so dynamically. The 7z.so library included in the package causes the OS to freeze if dynamically loaded by a program compiled with the older headers.

My current workaround is to use the older version of 7z.so.
