Hi RKY. I just recently started to plug my own c++ compiler together. These are the files I downloaded:
gcc270-base
gcc270-c
gcc270-inclib
gcc270-objc020
These are the gcc files. Since im a beginner as well you might more or less than these files. But its a start.
In addition you will need the ixemul library. You can get this from aminet as well.
The last most important file is the NDK file. Experienced HELL trying to find this by myself but Piru helped me out and gave this link
NDK filesIf you need any good tutorials consider these
thinking in c++ACMBoth are free to download and filled with examples
Happy programming. Call back if you experience problems when setting up your compiler
