⚙ gm_nasm

This is a set of Garry's Mod modules written by me mostly under linux32 (elf_i386) srcds on Netwide Assembler for fun and experience in assembler.

💾 Modules:

• gmsv_hello_linux: The simplest example. Outputs Hello from Netwide Assembler! to the console at startup.
• gmsv_crc32_linux: Example with adding a own function to the lua global table.
  The CRC-32 algorithm is implemented as an function example.
  Instead of declaring a ready CRC Table, it is generated in runtime by poly 0xEDB88320.
  Function: number CRC32(string stringToChecksum). Btw this is much faster than util.CRC.
• Something else in the future (if I write more)

🔨 Build:

1. Install nasm: sudo apt install nasm
2. Copy lua_shared_srv.so from srcds folder to this folder (where Makefile)
   Tip: file location in srcds: Steam\steamapps\common\GarrysModDS\garrysmod\bin\lua_shared_srv.so
3. Run make

🚀 Run:

1. Copy dll's from folder to lua/bin folder of srcds
   Tip: lua binary location in srcds: Steam\steamapps\common\GarrysModDS\garrysmod\lua\bin
2. Change (or add) top line in GarrysModDS\srcds_run:
   Note: this is to ensure that the dynamic linker finds all necessary dependencies when loading the module

export LD_LIBRARY_PATH=".:bin:garrysmod/bin:$LD_LIBRARY_PATH"

3. Run modules in game!
