This document outlines three scripts: a CMake build script, an emcc compiler script, and a dpmaster script, which are used to build and compile various projects, including a C file and a Quake3Arena file. Each script utilizes specific flags and options to generate different output types, such as Unix Makefiles, WebAssembly code, and JavaScript files.

CMake Build Script

The first command is a CMake build script:

cmake -G "Unix Makefiles" -H. -Bbuild -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=/usr/local/bin/gcc-9 -DCMAKE_CXX_COMPILER=/usr/local/bin/g++-9

This command:

• Uses the "Unix Makefiles" generator (-G)
• Specifies the current directory (-H.) as the source directory
• Specifies the build directory as the output directory (-Bbuild)
• Sets the CMake build type to "Release" (-DCMAKE_BUILD_TYPE=Release)
• Specifies the C compiler (-DCMAKE_C_COMPILER=/usr/local/bin/gcc-9)
• Specifies the C++ compiler (-DCMAKE_CXX_COMPILER=/usr/local/bin/g++-9)

emcc Compiler Script

The next two commands compile a C file using the emcc compiler from the Emscripten SDK:

./code/xquakejs/lib/emsdk/upstream/emscripten/emcc -O1 -s STANDALONE_WASM -s EXPORTED_FUNCTIONS="['_MSG_initHuffman', '_Huff_Decompress', '_Huff_Compress']" -s EXPORT_NAME="huffman"./code/xquakejs/lib/huffman.c -o./code/xquakejs/lib/huffman.js

./code/xquakejs/lib/emsdk/upstream/emscripten/emcc -O1 -s SAFE_HEAP=1 -s WASM=0 -s EXTRA_EXPORTED_RUNTIME_METHODS="['getValue', 'allocate']" -s EXPORTED_FUNCTIONS="['_MSG_initHuffman', '_Huff_Decompress', '_Huff_Compress', '_HuffmanGetSymbol']" -s EXPORT_NAME="huffman"./code/xquakejs/lib/huffman.c -o./code/xquakejs/lib/huffman.js

These commands:

• Compile the huffman.c file using emcc
• Specify optimization level 1 (-O1)
• Generate standalone WebAssembly code (-s STANDALONE_WASM)
• Export specific functions (-s EXPORTED_FUNCTIONS)
• Specify the export name (-s EXPORT_NAME)
• Compile the file to JavaScript (-o./code/xquakejs/lib/huffman.js)

dpmaster Script

The final command is a dpmaster script:

./dpmaster -L --log-file /Users/briancullinan/Downloads/dpmaster-2.2/dpmaster.log -v -g Quake3Arena options=send-empty-servers

This command:

• Runs the dpmaster tool with the -L option
• Specifies the log file (--log-file)
• Enables verbose mode (-v)
• Generates a Quake3Arena file (-g Quake3Arena)
• Specifies options (options=send-empty-servers)
