With GNU tar on Linux you can run tar -I lz4 to run tar with the lz4 compression algorithm, given that lz4 is installed.
In the Windows port, when trying to run tar -I lz4, I get the following error:
tar: invalid option -- I
Moreover (and this is a different bug), when trying to use the --use-compress-program flag instead, It does recognise it as a valid flag, but produces the following error:
tar: Cannot fork: Function not implemented
Seems like the ported C code (AFAIK) is trying to make the syscall fork(), which has is not implemented in Windows thus creating the error.
The error occurred on windows when trying to run:
tar --use-compress-program lz4 -cf [PATH]\temp.tar.lz4 .
Can those two bugs be fixed?
