I am in the process of switching from SAS/C to StormC 4 (based on GCC btw).
I have installed GCC before.There is more than one archive to download, so you may need to download these parts (see Aminet dev/gcc)
gcc270-base.lha (common files)
gcc270-c.lha (C compiler)
gcc270-c++.lha (C++ compiler)
gcc270-doc.lha (documentation)
gcc270-inclib.lha (Headers and Link libraries)
gcc270-readme.lha (Readme)
They all need to go in the same directory structure
e.g. DH0:gcc\...
PS You can get StormC cheap (£25) from Haage and Partner if you would prefer a straightforward installation and a pretty good IDE interface.
