• m4
• autoconf
• automake
• libtool
• fuse-dev
• e2fsprogs-dev

$ apt-get install m4 autoconf automake libtool
$ apt-get install libfuse-dev e2fslibs-dev
	
$ ./autogen.sh

$ make
$ sudo make install

You can use checkinstall or some other equivalent tool to generate install package for your distribution.

Mac OS:

Dependecies:

OSXfuse io no need to install with MacFuse compatibility.

The easiest way is using Homebrew:

$ brew install e2fsprogs m4 automake autoconf libtool pkg-config
$ git clone https://github.com/alperakcan/fuse-ext2.git
$ cd fuse-ext2
$ ./autogen.sh
$ ./configure \
    PKG_CONFIG_PATH="$(brew --prefix e2fsprogs)/lib/pkgconfig" \
    CFLAGS="-idirafter/$(brew --prefix e2fsprogs)/include -idirafter/usr/local/include/osxfuse" \
    LDFLAGS="-L$(brew --prefix e2fsprogs)/lib"
$ make
$ sudo make install         #<-- To install on the current system
     or
$ make package              #<-- To create an install package in the current directory

Bugs

• Multithread support is broken for now, so forcing fuse to work single thread.
• there are no known bugs for read-only mode, read only mode should be ok for every one.
• although, write support is available please do not mount your filesystems with write support unless you do not have anything to loose.

Please send output the output of below command while reporting bugs as GitHub Issue. Before submitting a bug report, please look at the existing issues first.

$ /usr/local/bin/fuse-ext2 -v /dev/path /mnt/point -o debug
