### Bootstrapping
|
||||
|
||||
Most of Z3's CMake files do not live in their correct location. Instead those
|
||||
files live in the ``contrib/cmake`` folder and a script is provided that will
|
||||
copy (or hard link) the files into their correct location.
|
||||
|
||||
To copy the files run
|
||||
|
||||
```
|
||||
python contrib/cmake/bootstrap.py create
|
||||
```
|
||||
|
||||
in the root of the repository. Once you have done this you can now build Z3 using CMake.
|
||||
Make sure you remember to rerun this command if you pull down new code/rebase/change branch so
|
||||
that the copied CMake files are up to date.
|
||||
|
||||
To remove the copied files run
|
||||
|
||||
```
|
||||
python contrib/cmake/bootstrap.py remove
|
||||
```
|
||||
|
||||
Note if you plan to do development on Z3 you should read the developer
|
||||
notes on bootstrapping in this document.
|
||||
|
||||
What follows is a brief walk through of how to build Z3 using some
|
||||
of the more commonly used CMake generators.

|
||||
### Boostrapping the CMake build
|
||||
|
||||
Z3's CMake system is experimental and not officially supported. Consequently
|
||||
Z3's developers have decided that they do not want the CMake files in the
|
||||
``src/`` and ``examples/`` folders. Instead the ``contrib/cmake/bootstrap.py``
|
||||
script copies or hard links them into the correct locations. For context
|
||||
on this decision see https://github.com/Z3Prover/z3/pull/461 .
|
||||
|
||||
The ``contrib/cmake/bootstrap.py create`` command just copies over files which makes
|
||||
development harder because you have to copy your modifications over to the
|
||||
files in ``contrib/cmake`` for your changes to committed to git. If you are on a UNIX like
|
||||
platform you can create hard links instead by running
|
||||
|
||||
```
|
||||
contrib/cmake/boostrap.py create --hard-link
|
||||
```
|
||||
|
||||
Using hard links means that modifying any of the "copied" files also modifies the
|
||||
file under version control. Using hard links also means that the file modification time
|
||||
will appear correct (i.e. the hard-linked "copies" have the same file modification time
|
||||
as the corresponding file under version control) which means CMake will correctly reconfigure
|
||||
when invoked. This is why using symbolic links is not an option because the file modification
|
||||
time of a symbolic link is not the same as the file modification of the file being pointed to.
|
||||
|
||||
Unfortunately a downside to using hard links (or just plain copies) is that if
|
||||
you pull down new code (i.e. ``git pull``) then some of the CMake files under
|
||||
version control may change but the corresponding hard-linked "copies" will not.
|
||||
|
||||
This mean that (regardless of whether or not you use hard links) every time you
|
||||
pull down new code or change branch or do an interactive rebase you must run
|
||||
(with or without ``--hard-link``):
|
||||
|
||||
```
|
||||
contrb/cmake/boostrap.py create
|
||||
```
|
||||
|
||||
in order to be sure that the copied CMake files are not out of date.
|
||||
|
||||

This script is used to copy or delete the
|
||||
CMake build system files from the contrib/cmake
|
||||
folder into the their correct location in the Z3
|
||||
repository.
|
||||
This script is an artifact of compromise that was
|
||||
made when the CMake build system was first introduced
|
||||
(see #461).
|
||||
|
||||
It offers two modes
|
||||
|
||||
* create - This will symlink the ``cmake`` directory and copy (or hard link)
|
||||
the appropriate files into their correct locations in the repository.
|
||||
|
||||
* remove - This will remove the symlinked ``cmake``
|
||||
directory and remove the files added by the above
|
||||
methods.
|
||||
|
||||
This has the advantage
|
||||
that editing the hard link edits the underlying file
|
||||
(making development easier because copying files is
|
||||
not neccessary) and CMake will regenerate correctly
|
||||
because the modification time stamps will be correct.
|
||||
This script now does nothing. It remains only to not
|
||||
break out-of-tree scripts that build Z3 using CMake.
|
||||
|
||||
Eventually this script will be removed.

\brief Create a new (incremental) solver. This solver also uses a
|
||||
set of builtin tactics for handling the first check-sat command, and
|
||||
check-sat commands that take more than a given number of milliseconds to be solved.
|
||||
\brief Create a new solver. This solver is a "combined solver" (see
|
||||
combined_solver module) that internally uses a non-incremental (solver1) and an
|
||||
incremental solver (solver2). This combined solver changes its behaviour based
|
||||
on how it is used and how its parameters are set.
|
||||
|
||||
If the solver is used in a non incremental way (i.e. no calls to
|
||||
`Z3_solver_push()` or `Z3_solver_pop()`, and no calls to
|
||||
`Z3_solver_assert()` or `Z3_solver_assert_and_track()` after checking
|
||||
satisfiability without an intervening `Z3_solver_reset()`) then solver1
|
||||
will be used. This solver will apply Z3's "default" tactic.
|
||||
|
||||
The "default" tactic will attempt to probe the logic used by the
|
||||
assertions and will apply a specialized tactic if one is supported.
|
||||
Otherwise the general `(and-then simplify smt)` tactic will be used.
|
||||
|
||||
If the solver is used in an incremental way then the combined solver
|
||||
will switch to using solver2 (which behaves similarly to the general
|
||||
"smt" tactic).
|
||||
|
||||
Note however it is possible to set the `solver2_timeout`,
|
||||
`solver2_unknown`, and `ignore_solver1` parameters of the combined
|
||||
solver to change its behaviour.
|
||||
|
||||
The function #Z3_solver_get_model retrieves a model if the
|
||||
assertions is satisfiable (i.e., the result is \c
|
||||
Z3_L_TRUE) and model construction is enabled.
|
||||
The function #Z3_solver_get_model can also be used even
|
||||
if the result is \c Z3_L_UNDEF, but the returned model
|
||||
is not guaranteed to satisfy quantified assertions.
|
||||
|
||||
\remark User must use #Z3_solver_inc_ref and #Z3_solver_dec_ref to manage solver objects.
|
||||
Even if the context was created using #Z3_mk_context instead of #Z3_mk_context_rc.
