MacFUSE

[](macfuse/macfuse-icon.png%3Fattredirects=0) [MacFUSE](http://code.google.com/p/macfuse/) is a filesystem in userland. It runs well on PureDarwin and can be used to mount sshfs, ramdisk and other FUSE-based filesystems. It is, according to its maintainers, "The Easiest and Fastest Way to Create File Systems for Mac OS X" (and PureDarwin, one might add).

Installing MacFUSE

MacFUSE can be installed from the official MacFUSE.pkg (from the MacFUSE site) on PureDarwin with the following commands:

cd / ; gunzip -c "MacFUSE.pkg/Contents/Resources/10.5/MacFUSE Core.pkg/Contents/Archive.pax.gz"  | pax -r chown -R root:wheel /Library/Filesystems/fusefs.fs/Support/fusefs.kext   chmod -R 755 /Library/Filesystems/fusefs.fs/Support/fusefs.kext

Now MacFUSE is ready to use on PureDarwin.

sshfs

sshfs allows you to mount volumes over SSH.

Install the sshfs filesystem with curl "http://macfuse.googlecode.com/svn/trunk/filesystems/sshfs/binary/sshfs-static-leopard" > /usr/sbin/mount_sshfs chmod a+x /usr/sbin/mount_sshfs

Now we can mount a remote filesystem with mkdir /Volumes/SSHVolume/ mount_sshfs [email protected]:/ /Volumes/SSHVolume/ -oauto_cache,reconnect,volname=SSHVolume

ramdisk

Status: functional in PureDarwin (Darwin 9)

ramdisk is, as its name implies, a ramdisk implemented in MacFUSE. Install it with

svn co http://thebends.googlecode.com/svn/trunk/ramdisk/ ramdisk cd ramdisk/ make cp ramdisk /usr/sbin/mount_ramdisk cd - rm -rf ramdisk/

Now we can use the ramdisk command to create ramdisks:

mkdir /some/path mount_ramdisk /some/path

Troubleshooting in building ramdisk and targetting Darwin 9

In case you plan to build it on Darwin 10, a couple of adjustements must be made. Edit the Makefile and replace this line in order to be able to run it on Darwin 9:

CC = g++

by this line CC = MACOSX_DEPLOYMENT_TARGET=10.5  g++

And this line

OPTS = -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 by this line OPTS = -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -arch i386

Problem: If you encounter:

file.cpp: In constructor 'ramdisk::File::File(ramdisk::Dir*, mode_t)': file.cpp:17: error: 'assert' was not declared in this scope cc1plus: warnings being treated as errors or encounter

dir.cpp: In function 'void ramdisk::assertNoSubdirs(const std::string&)': dir.cpp:11: error: 'assert' was not declared in this scope [...] dir.cpp:228: error: 'assert' was not declared in this scope Solution: Simply add #include <assert.h> in file.h per example.

Problem: cc1plus: warnings being treated as errors file.cpp: In member function 'virtual size_t ramdisk::File::Read(char*, size_t, off_t)': file.cpp:26: warning: comparison between signed and unsigned integer expressions Solution: Replace in file.cpp this line

  if (offset < len) {

by this line

  if ((size_t) offset < len) {

Then after a make clean' and make', everything should be fine and run on a PureDarwin release based on Darwin9:

MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c node.cpp MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c file.cpp MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c dir.cpp MACOSX_DEPLOYMENT_TARGET=10.5 g++ -Wall -Werror -g -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -c ramdisk.cpp ar rcs libcommon.a node.o file.o dir.o ramdisk.o MACOSX_DEPLOYMENT_TARGET=10.5 g++  -D_FILE_OFFSET_BITS=64 -D__FreeBSD__=10 -DFUSE_USE_VERSION=26 -o ramdisk main.cpp -L. -lcommon -lfuse
