Prerequisites:

For sysadmins

To install in /usr/local/{include,lib,bin,man}:

    ./configure && make -j8 install

For developers with an unprivileged account

Typically you'll already have

    export LD_LIBRARY_PATH="$HOME/lib"
    export LIBRARY_PATH="$HOME/lib"
    export CPATH="$HOME/include"
    export PATH="$HOME/bin:$PATH"

in $HOME/.profile. To install in $HOME/{include,lib,bin,man}:

    ./configure --prefix=$HOME && make -j8 install

For distributors creating a package

Run

    ./configure --prefix=/usr && make -j8

and then follow your usual packaging procedures for the build/0/package files:

    build/0/package/include/mceliece.h
    build/0/package/lib/libmceliece*
    build/0/package/bin/mceliece*
    build/0/package/man/man3/*.3
    build/0/package/man/man1/*.1

The libcpucycles and librandombytes packages are build-time and run-time prerequisites; the python3 and compiler packages are only build-time prerequisites.

More options

You can run

    ./configure --host=amd64

to override ./configure's guess of the architecture that it should compile for. The architecture controls which implementations to try (see crypto_*/*/*/architectures) and which compilers to try (see compilers/*).

Inside the build directory, 0 is symlinked to amd64 for --host=amd64. Running make clean removes build/amd64. Re-running ./configure automatically starts with make clean.

A subsequent ./configure --host=arm64 will create build/arm64 and symlink 0 -> arm64, without touching an existing build/amd64. However, cross-compilers aren't yet selected automatically.
