LibDsk is a library intended to give transparent access to floppy drives and to the "disc image files" used by emulators to represent floppy drives.

It is intended for use in:

• Emulator tools: converting between real floppy discs and disc images, as CPCTRANS / PCWTRANS do under DOS.
• Filesystem utilities: CPMTOOLS is configurable to use LibDsk , thus allowing the use of CPMTOOLS on emulator .DSK images. To do this, install LibDsk and then build CPMTOOLS , using ./configure --with-libdsk. For CPMTOOLS 1.9 or 2.0, you will also need to apply this patch.
• Emulators: it is possible to use LibDsk as part of an emulator's floppy controller emulation, thus giving the emulator transparent access to .DSK files or real discs.

You will need an ANSI standard C compiler, prefered is the GNU CC. Optional you can build against the compression libraries zlib and libbz2 and also you can build an Java Native Interface binding to LibDsk. You can use LibDsk under DOS, Windows, Linux and MacOS.

sudo apt-get install zlib1g-dev
sudo apt-get install libbz2-dev

git clone https://github.com/lipro-cpm4l/libdsk.git
cd libdsk

./configure --with-zlib --with-bzlib
make all
sudo make install

A few parts of the source code are based on the work of other authors:

• Mark Ogden: Fixed some memory corruption issues detected by VS2017 analysis. Widened total_sectors32 to 32 bits in dskform. Swapped "sectors / track" and "sectors / cylinder" captions in dskutil.
• Steven Fosdick: Fixed compilation issue on recent glibc.
• Emulix75: New disk image format implemented, SAP.
• Will Kranz: Teledisk read-only support for 'advanced' compression. Based on wteledsk decompression code by Will Kranz (relicensed under LGPLv2, with permission).
• Ralf-Peter Nerlich: Correct the description of the 'W' command in dskutil. All utilities now use basename() (if available) to trim paths from argv[0]. Replacement CopyQM driver.
• Jurgen Sievers: Bug fixes an buffer overflow in rcpmfs driver when renaming a file with a full 8.3 name and a nonzero user number.
• Alistair John Bush: Patched Makefile.am to pass JAVACFLAGS to Java compiler.
• Sven Klose: Corrected a compilation problem on FreeBSD.
• Stuart Brady: Added a new geometry (FMT_TRDOS640).
• Ramlaid <www.ramlaid.com>: Modified cpcemu driver so that the dsk_trkids() function more accurately reflects the result from a real disk. Doesn't leak file handles if file not SQ compressed. Uses the passed sector size in dsk_xread() / dsk_xwrite() of the ntwdm driver rather than the sector size in the geometry structure.
• Daniel Black: Corrected an install bug in Makefile.am.
• Simon Owen: Added ntwdm driver.
• Philip Kendall: Added dsk_dirty() function.
• Per Ola Ingvarsson: A read-only CopyQM driver and CopyQM format documentation.
• Thierry Jouin: Bug fixes in the extended .DSK format handler.
• Darren Salt: Bug fixes in the example utilities. Manual pages added to the distribution.
• Cliff Lawson: Support added for .CFI format (a strange format used by Cliff Lawson to distribute Amstrad PC boot floppies).
• Kevin Thacker: Make libdsk compile in Microsoft Visual C++.
