|
|
|
|
|
in-memory graph database featuring runtime native query compiling, lock free

## dependencies
|
|
|
|
|
|
|
|
|
|
Memgraph can be compiled using any modern c++ compiler. It mostly relies on
|
|
|
|
|
the standard template library, however, some things do require external
|
|
|
|
|
libraries.
|
|
|
|
|
|
|
|
|
|
Some code contains linux-specific libraries and the build is only supported
|
|
|
|
|
on a 64 bit linux kernel.

|
|
|
|
|
|
|
|
|
* linux
|
|
|
|
|
* clang 3.5 or Gcc 4.8 (good c++11 support, especially lock free atomics)
|
|
|
|
|
* boost 1.55 (or something, probably works with almost anything)
|
|
|
|
|
* lexertl (2015-07-14)

|
|
|
* lemon (parser generator)
|

|
|
|
* catch (for compiling tests)
