Hey everyone,<br><br>This took many hours searching and dozens of reinstallations of Cygwin and Eclipse. Finally I figured out what needs to be done to resolve the following error:<br><br><div style="margin-left: 40px;">**** Build of configuration Debug for project Lab3_Sum ****<br>
<br>**** WARNING: The "Debug" Configuration may not build ****<br>**** because it uses the "Cygwin GCC" ****<br>**** tool-chain that is unsupported on this system. ****<br><br>**** Attempting to build... **** <br>
</div><br>Eclipse doesn't know where to look for the 'Cygwin GCC' tool-chain, and never asks you to tell it where it's located. Changing the Windows $PATH variable isn't enough on its own.<br><br>Attached is a registry file that you need to import into your registry to resolve the issue, it should work with Windows XP/Vista/7. I've personally tested it on my laptop running Windows 7 Ultimate and my computer at work running Windows XP SP3.<br>
<br>If you installed Cygwin into another directory besides C:\cygwin - you must edit the file to change the directory (in 3 places) before importing. For those whose anti-virus programs blocks a file download with a .reg extension, copy the following section below, paste it into Notepad and save it as 'cygwin_reg.reg' - without the quotes. Then double click it and click ok/yes to import into the registry. Restart Eclipse and try to build a program and the warning should no longer be there:<br>
