To build and use jai, you will need the following:

 - A modern C++ compiler (tested with gcc 15 and clang 22)

 - A modern version of Linux (kernel 6.13 and later should work)

 - libmount (possible distro package names: util-linux-libs, libmount-dev)

 - libacl (possible distro package names: acl, libacl1-dev)

In Ubuntu, you may need the following to get a modern compiler:

    sudo add-apt-repository ppa:ubuntu-toolchain-r/test
    sudo apt update
    sudo apt install g++-15 libmount-dev libacl1-dev pkg-config
    export CXX=g++-15

To build from a release tarball, run:

    ./configure
    make

To build from a git checkout, you will also need to install autoconf,
automake, and pandoc (to format the man page).  Run:

    ./autogen.sh
    ./configure
    make

To install (must be root for setuid):

    sudo make install
    sudo systemd-sysusers

To override the installation prefix:

    ./configure --prefix=/usr
    make
    sudo make install
    sudo systemd-sysusers

Most of the tests require a setuid root version of jai to test.  Since
people's build directories are often mounted nosuid, make `jai.suid`
in the top of your build directory a symbolic link to a place with a
setuid executable.  You can run:

    sudo test/setup-setuid.sh

to do this automatically in /var/tmp, which is generally mounted
setuid capable.
