In addition to replacing Qt5 with Qt6 in CMakeLists.txt
two small changes to the code are needed to make things build
on Qt 6 (which in turn is needed for Apple M1/M2 support).
The cost of this change is that when building on Qt 5, at least
version 5.14 is needed.
Certain older but still used Linux distributions such as
Ubuntu 10.04 LTS still use 5.12, so revert this commit if you
are building on those...
When no more directory entries are available in the existing
cluster(s) of a directory on FAT32, we allocate an
extra cluster.
Make sure to zero out that new cluster, as disk checking utilities
may not stop reading when reaching an end of directory marker but
read the rest of cluster as well.
So there must not be any garbage data from a previously deleted file
in the sector there.
Also add checks to prevent getting in an endless loop on
encoutering circular "next cluster" references.
- No longer relies on operating system for mounting FAT partition
when applying 'advanced settings'
- change '__attribute__ ((packed))' to '#pragma pack()' as the
mingw version we are using for Windows has a bug with the former
Minimal implementation for reading/writing files in the root
directory of a FAT16/FAT32 file system.
Can read/write from raw disk devices, and no longer relies on
operating system support for mounting the file system.
Currently assumes Imager will always be run on 'little endian'
architectures such as Intel and ARM (at least under Linux).
If there is a use-case for big-endian (anybody still using Sparc?)
this may be revisited later.
