# Build instructions
### Checking requirements
There are several software requirements for building Metamod-r:

#### Windows
<pre>
Visual Studio 2015 (C++14 standard) and later
</pre>

#### Linux
<pre>
git >= 1.8.5
cmake >= 3.10
GCC >= 4.9.2 (Optional)
ICC >= 15.0.1 20141023 (Optional)
LLVM (Clang) >= 6.0 (Optional)
</pre>

### Building

#### Windows
Use `Visual Studio` to build, open `msvc/metamod.sln` and just select from the solution configurations list `Release` or `Debug`

#### Linux

* Optional options using `build.sh --compiler=[gcc] --jobs=[N] -D[option]=[ON or OFF]` (without square brackets)

<pre>
-c=|--compiler=[icc|gcc|clang]  - Select preferred C/C++ compiler to build
-j=|--jobs=[N]                  - Specifies the number of jobs (commands) to run simultaneously (For faster building)

<sub>Definitions (-D)</sub>
DEBUG                           - Enables debugging mode
USE_STATIC_LIBSTDC              - Enables static linking library libstdc++
</pre>

* ICC          <pre>./build.sh --compiler=intel</pre>
* LLVM (Clang) <pre>./build.sh --compiler=clang</pre>
* GCC          <pre>./build.sh --compiler=gcc</pre>
