HOW TO BUILD

Windows

Requires:

• nasm
• perl
• VC build tools

Install and Compile:

1. Run Install.bat inside the Scripts folder.
2. Enter the VC Path (e.g., C:\Program Files (x86)\Microsoft Visual Studio\2019).
3. Enter the Perl path (e.g., C:\Strawberry).
4. Enter the NASM path (e.g., C:\Users\Tobias\AppData\Local\bin\NASM).

[WARNING] Uses 'setx' to set NASM path to the system environment.

Linux

Build all:

• make all (include dependencies)
• make build
• make sandbox

Build dependencies:

• make cryptopp
• make openssl-download
• make openssl-unpack
• make openssl-configure
• make openssl-build
• make openssl-install

Clean:

• make cryptopp-clean
• make openssl-clean

Clean all:

• make clean

Build:

• make netcore
• make netclient
• make netserver
• make netwebsocket

Build sandbox:

• make sandboxclient
• make sandboxserver
• make sandboxwebsocket
• make sandboxfeatures (use it to test functionality of NetCore Features)
