Abstract
We first describe how the Coda distributed filesystem was ported to
Windows 95 and 98. Coda consists of user level cache managers and
servers and kernel level code for filesystem support. Severe reentrancy
difficulties in the Win32 environment on this platform were overcome by
extending the DJGPP DOS C compiler package with kernel level support for
sockets and more flexible memory management. With this support library
and kernel modules for Windows 9x filesystems in place, the Coda file
system client could be ported with very little patching and will likely
soon run as well on Windows 9x as on Linux. We ported Coda file servers
to Windows NT. For fileservers the Cygwin32 kit was used. We will not
report here on the port of the Coda client to Windows NT, which is in an
early stage. In both cases cross compilation from a Linux environment
was most helpful to get a good development environment.
