I tried to run ~/MCP/jars/forge/install.sh (I'm trying to give an idea of how the folders are setup, in case that is part of the problem), and everything worked out fine until I was greeted with the following error:

I'm not sure what to do here. I am running CrunchBang Linux. I don't know how to install JDK properly, and I'm not sure if it is properly installed or not. The javac command doesn't work, but I have JDK 7 located in /usr/local/bin. Any ideas of what to do?

first try "java" on CLI

The java command does indeed work. I followed this tutorial to install JDK: http://www.wikihow.com/Install-Oracle-Java-JDK-on-Ubuntu-Linux. Now I am not getting the previous error, but instead I am getting

== MCP 8.04 (data: 8.04, client: 1.6.2, server: 1.6.2) ==
"scalac" is not found on the PATH.  Scala files will not be recompiled
!! retroguard check FAILED !!
Command '"java" -jar runtime/bin/retroguard.jar --version' returned non-zero exit status 2

 

Any ideas?

not sure really this didnt happen to me

 

note1: if scalac cannot be found it should NOT be a problem as scala is not mandatory for forge

i see your path already has mcp installed, but forge doesnt need to have mcp installed anymroe because it will download it itself. can you retry using only forge  ? (see wiki for install instruction)

Yes! I managed to get it to work after installing JRE in the same way. Thank you so much for your very quick responses! I'm very excited to get to work. I'm marking this thread as solved.

 

Edit: One last question. How do I mark this thread as solved?
