## Windows x86. Using Microsoft Visual Studio 6
Microsoft Visual Studio 6 is very old, but if you still have it installed, you can use it to build this hlsdk. There are no project files, but two `.bat` files, for server and client libraries. They require variable **MSVCDir** to be set to the installation path of Visual Studio:

## Other platforms
Building on other Unix-like platforms (e.g. FreeBSD) is supported.
## Nintendo Switch
### Prerequisites
Install C and C++ compilers (like gcc or clang), cmake and make (or gmake)
1. Set up [`dkp-pacman`](https://devkitpro.org/wiki/devkitPro_pacman).
2. Install dependency packages:
```
sudo dkp-pacman -S switch-dev dkp-toolchain-vars switch-mesa switch-libdrm_nouveau switch-sdl2
```
3. Make sure the `DEVKITPRO` environment variable is set to the devkitPro SDK root:
```
export DEVKITPRO=/opt/devkitpro
```
4. Install libsolder:
```
source $DEVKITPRO/switchvars.sh
git clone https://github.com/fgsfdsfgs/libsolder.git
make -C libsolder install
```
### Building using CMake
```
mkdir build && cd build
aarch64-none-elf-cmake -G"Unix Makefiles" -DCMAKE_PROJECT_HLSDK-PORTABLE_INCLUDE="$DEVKITPRO/portlibs/switch/share/SolderShim.cmake" ..
make -j
```
### Building using waf
```
./waf configure -T release --nswitch
./waf build
```
## Other platforms
Building on other architectures (e.g x86_64 or arm) and POSIX-compliant OSes (e.g. FreeBSD) is supported.
### Prerequisites
Install C and C++ compilers (like gcc or clang), cmake and make.
