Linux

This is the easiest option, but you may not get the latest version of the SDK right away.

You will also need to install the ARM toolchain of Wonderful Toolchains. Follow the instructions in this link: https://wonderful.asie.pl/docs/getting-started/#linux
Now, install the ARM toolchain of Wonderful Toolchains, as well as the BlocksDS packages.
```
export PATH=/opt/wonderful/bin:$PATH
wf-pacman -Syu
wf-pacman -S toolchain-gcc-arm-none-eabi
```
Install the following if you plan to develop binaries for the DSP of the DSi:
```
wf-pacman -S toolchain-llvm-teak-llvm
```
For the latest stable version of BlocksDS, run:
```
wf-pacman -S thirdparty-blocksds-toolchain
```
To install the documentation and examples you can install:
```
wf-pacman -S thirdparty-blocksds-docs
```
For the latest unstable version, install the following packages instead:
```
wf-pacman -S thirdparty-blocksds-git-toolchain \
             thirdparty-blocksds-git-docs
```
(Optional step) You can also install some third party libraries like NightFox’s Lib and Nitro Engine using wf-pacman:
```
wf-pacman -S thirdparty-blocksds-nflib \
             thirdparty-blocksds-nitroengine
```
wf-pacman installs BlocksDS in /opt/wonderful/thirdparty/blocksds/. This isn’t the standard location (wf-pacman can only write files to /opt/wonderful/) so you need to do one of the two following options:
1. Create a symlink:
```
ln -s /opt/wonderful/thirdparty/blocksds /opt/blocksds
```
2. Set your environment variables correctly:
```
export BLOCKSDS=/opt/wonderful/thirdparty/blocksds/core
export BLOCKSDSEXT=/opt/wonderful/thirdparty/blocksds/external
```
Whenever you need to update the SDK, run:
```
wf-pacman -Syu
```
Now you can try to build one of the BlocksDS examples. They are available at path /opt/wonderful/thirdparty/blocksds/core/examples/. From there, for example, go to graphics_3d/volumetric_shadow and type make. This will generate a NDS ROM that you can try with an emulator or a flashcart.

You can also try one of the open source projects made with BlocksDS that are listed here.
