It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:
- unit tests depending on building, functional tests don't (e.g. when
we test already-built Nix)
- unit tests can be installed, functional tests cannot
- unit tests neeed extra libraries (GTest, RapidCheck), functional
tests need extra executables (jq).
- unit tests are run by `make check`, functional tests are run by `make
installcheck`
Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.
I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

# Prerequisites
|
||
|
||
- GNU Autoconf (<https://www.gnu.org/software/autoconf/>) and the
|
||
autoconf-archive macro collection
|
||
(<https://www.gnu.org/software/autoconf-archive/>). These are
|
||
needed to run the bootstrap script.
|
||
|
||
- GNU Make.
|
||
|
||
- Bash Shell. The `./configure` script relies on bashisms, so Bash is
|
||
required.
|
||
|
||
- A version of GCC or Clang that supports C++20.
|
||
|
||
- `pkg-config` to locate dependencies. If your distribution does not
|
||
provide it, you can get it from
|
||
<http://www.freedesktop.org/wiki/Software/pkg-config>.
|
||
|
||
- The OpenSSL library to calculate cryptographic hashes. If your
|
||
distribution does not provide it, you can get it from
|
||
<https://www.openssl.org>.
|
||
|
||
- The `libbrotlienc` and `libbrotlidec` libraries to provide
|
||
implementation of the Brotli compression algorithm. They are
|
||
available for download from the official repository
|
||
<https://github.com/google/brotli>.
|
||
|
||
- cURL and its library. If your distribution does not provide it, you
|
||
can get it from <https://curl.haxx.se/>.
|
||
|
||
- The SQLite embedded database library, version 3.6.19 or higher. If
|
||
your distribution does not provide it, please install it from
|
||
<http://www.sqlite.org/>.
|
||
|
||
- The [Boehm garbage collector](http://www.hboehm.info/gc/) to reduce
|
||
the evaluator’s memory consumption (optional). To enable it, install
|
||
`pkgconfig` and the Boehm garbage collector, and pass the flag
|
||
`--enable-gc` to `configure`.
|
||
|
||
- The `boost` library of version 1.66.0 or higher. It can be obtained
|
||
from the official web site <https://www.boost.org/>.
|
||
|
||
- The `editline` library of version 1.14.0 or higher. It can be
|
||
obtained from the its repository
|
||
<https://github.com/troglobit/editline>.
|
||
|
||
- The `libsodium` library for verifying cryptographic signatures
|
||
of contents fetched from binary caches.
|
||
It can be obtained from the official web site
|
||
<https://libsodium.org>.
|
||
|
||
- Recent versions of Bison and Flex to build the parser. (This is
|
||
because Nix needs GLR support in Bison and reentrancy support in
|
||
Flex.) For Bison, you need version 2.6, which can be obtained from
|
||
the [GNU FTP server](ftp://alpha.gnu.org/pub/gnu/bison). For Flex,
|
||
you need version 2.5.35, which is available on
|
||
[SourceForge](http://lex.sourceforge.net/). Slightly older versions
|
||
may also work, but ancient versions like the ubiquitous 2.5.4a
|
||
won't.
|
||
|
||
- The `libseccomp` is used to provide syscall filtering on Linux. This
|
||
is an optional dependency and can be disabled passing a
|
||
`--disable-seccomp-sandboxing` option to the `configure` script (Not
|
||
recommended unless your system doesn't support `libseccomp`). To get
|
||
the library, visit <https://github.com/seccomp/libseccomp>.
|
||
|
||
- On 64-bit x86 machines only, `libcpuid` library
|
||
is used to determine which microarchitecture levels are supported
|
||
(e.g., as whether to have `x86_64-v2-linux` among additional system types).
|
||
The library is available from its homepage
|
||
<http://libcpuid.sourceforge.net>.
|
||
This is an optional dependency and can be disabled
|
||
by providing a `--disable-cpuid` to the `configure` script.
|
||
|
||
- Unless `./configure --disable-unit-tests` is specified, GoogleTest (GTest) and
|
||
RapidCheck are required, which are available at
|
||
<https://google.github.io/googletest/> and
|
||
<https://github.com/emil-e/rapidcheck> respectively.
