# Build From Source

## Without a build script

Pocketlang has zero dependencies and you don't even require a build system, just a c99 compiler is enought, and it can be compiled with the following command.

Using gcc
```
gcc -o pocket cli/*.c src/*.c -Isrc/include -lm
```

Using MSVC
```
cl /Fepocket cli/*.c src/*.c /Isrc/include && rm *.obj
```

For other compilers it's the same (If you weren't able to compile it with any c99 compatible compiler, please report by [opening an issue](https://github.com/ThakeeNathees/pocketlang/issues/new)). And add ` -Wno-int-to-pointer-cast` for gcc to suppress those warnings emitted when nan-tagging is enabled.

## Using a build script

You could find some of the build script for different build system in the `build/` direcroty. If you don't find a scirpt for your prifered system, request on github by [opening an issue](https://github.com/ThakeeNathees/pocketlang/issues/new) or feel free to contribute one.

## Makefile

```
cd build && make
```

## Batch script with MSVC

```
cd build && build
```
You don't require to run the script from a Visual Studio .NET Command Prompt, It'll search for the MSVS installation path and use it to compile. But if it can't, try running on VS command prompt.

## SCons

pocketlang mainly focused on [scons](https://www.scons.org/), and it's recommended to use it for contributions since it has various configurations and compiler support. It's a python based build system. You need to have python 3.6+ installed in your development environment. To install scons run `python3 -m pip install scons`. Make sure it's version is 3.0+ and for Visual Studio 2019 it require v3.1.1+. In Linux if scons using python2 instead of 3 you'll have to edit `/usr/local/bin/scons` or `~/.local/bin/scons` to ensure that it points to `/usr/bin/env python3` and not `python`

```
cd build && scons
```

You can specify the number of jobs scons to use to speed up the building process using the -j flag (-j6, -j8). To generate Visual Studio project files add `vsproj=true` argument when building. To compile using mingw in windows use `use_mingw=true` argument. If your build failed feel free to [open an issue](https://github.com/ThakeeNathees/pocketlang/issues/new).
