Downloads of MCIPM client packages (version 1.0.1):


Install Mod

To install the mod to Minecraft Forge, copy "mcipm-<version>.jar" into "mods" directory; you will also need to extract all files from "mcipm-dependencies-20200421.tar.bz2" into "mods" directory to provide the Java libraries it depends.

For example:

$ cd /path/to/your/minecraft/server/directory/
$ cp /path/to/mcipm-1.0.0.jar mods/
$ cd mods
$ tar -x -f /path/to/mcipm-dependencies-20200421.tar.bz2


Build/Install Client Tool

To build the client tool from source, simply extract the client source package, compile all ".c" files with your C compiler and link them together; for example:

$ tar -x -f /path/to/mcipm-client-1.0.1-src.tar.bz2
$ gcc -Wall -O1 *.c -o mcipm

To use the prebuilt binary package, simply extract the package and use the executable file, as it has no additional dependencies.
