# Realm Object Store
|
|
|
|
Cross-platform code used accross bindings. Binding developers can choose to use some or all the included functionality:
|
|
- `object_store`/`schema`/`object_schema`/`property` - contains the structures and logic used to setup and modify realm files and their schema.
|
|
- `shared_realm` - wraps the object_store apis to provide transactions, notifications, realm caching, migrations, and other higher level functionality.
|
|
- `object_accessor`/`results`/`list` - accessor classes, object creation/update pipeline, and helpers for creating platform specific property getters and setters.
|
|
- `parser`/`query_builder` - cross platform query parser and query builder - requires and object_accessor specialization for argument support. Depends on https://github.com/ColinH/PEGTL
|

|
## Building
|
|
|
|
The object store's build system currently only suports building for OS X. The object store itself can build for all Apple
|
|
platforms when integrated into a binding.
|
|
|
|
1. Install CMake. You can download an installer for OS X from the [CMake download page](https://cmake.org/download/), or install via [Homebrew](http://brew.sh):
|
|
```
|
|
brew install cmake
|
|
```
|
|
|
|
2. Generate build files:
|
|
|
|
```
|
|
cmake .
|
|
```
|
|
|
|
3. Build:
|
|
|
|
```
|
|
make
|
|
```
|
|
|
|
If you wish to build against a local version of core you can invoke `cmake` like so:
|
|
|
|
```
|
|
cmake -DREALM_CORE_VERSION=/path/to/realm-core
|
|
```
|
|
|
|
The given core tree will be built as part of the object store build.
|
|
|
|
### Building with Sanitizers
|
|
|
|
The object store can be built using ASan, TSan and/or UBSan by specifying `-DSANITIZE_ADDRESS=1`, `-DSANITIZE_THREAD=1`, or `-DSANITIZE_UNDEFINED=1` when inoking CMake.
|
|
Building with ASan requires specifying a path to core with `-DREAM_CORE_VERSION` as core needs to also be built with ASan enabled.
|
|
|
|
On OS X, the Xcode-provided copy of Clang only comes with ASan, and using TSan or UBSan requires a custom build of Clang.
|
|
If you have installed Clang as an external Xcode toolchain (using the `install-xcode-toolchain` when building LLVM), note that you'll have to specify `-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++` when running `cmake` to stop cmake from being too clever.

|
|
## Testing
|
|
|
|
```
|
|
make run-tests
|
|
```
