How to build
mtd-utils uses an autotools based build system. If you are building the git
tree, you first need to run `./autogen.sh`. This sets up the build system
and requires autoconf, automake and possibly other autotools to be installed.
After unpacking a tarball (or running autogen.sh) simply run:
$ ./configure
$ make
to build the package. This does not require autotools to be installed, but
does need pkg-config, make, etc...
There are a number of configure switches to tune the build.
Run `./configure --help` to get an overview.
For compiling mtd-utils, you need development packages for the following
dependency libraries:
zlib (optional dependency for mkfs.ubifs, mkfs.jffs2)
lzo2 (optional dependency for mkfs.ubifs, mkfs.jffs2)
zstd (optional dependency for mkfs.ubifs)
libuuid* (required by mkfs.ubifs)
libselinux (optional dependency for mkfs.ubifs)
openssl (optional dependency for mkfs.ubifs)
