## Install

Windows:

* <https://nim-lang.org/install_windows.html>
* <https://git-scm.com/download/win>

Linux:

```
$ sudo apt install mingw-w64 -y
$ sudo apt install nim -y
Or
$ curl https://nim-lang.org/choosenim/init.sh -sSf | sh
```

Dependencies:

```
Nim > nimble install winim nimcrypto zippy
```

## Compilation

Basic:

```
Nim > nim c program.nim
```

To not popup the console window:

```
Nim > nim c --app:gui program.nim
```

For the best size:

```
Nim > nim c -d:danger -d:strip --opt:size --passC=-flto --passL=-flto program.nim
```

For Windows on Linux:

```
$ nim c --cpu:amd64 --os:windows --gcc.exe:x86_64-w64-mingw32-gcc --gcc.linkerexe:x86_64-w64-mingw32-gcc program.nim
```

Add the needed relocation section to the resulting executable (from Windows):

```
Nim > nim c --passL:-Wl,--dynamicbase,--export-all-symbols program.nim
```
