If you’re attempting to install fink and getting this error when running the Bootstrap or if you simply wonder how you can install the Developer Tools, this post is for you.
“ERROR: There is no C compiler on your system. Make sure that the Developer Tools are installed.”
Short and Sweet
STEP 1.) Launch Xcode and from the top menu bar, select “Xcode” then “Preferences“.
STEP 2.) Select the “Downloads” icon and then highlight “Command Line Tools” and click the install button to the right. Wait for the download to finish.
STEP 3.) All Done! – Run the bootstrap again if your installing fink and received an error.
