83: What should I do if I have trouble building Emacs? First look in the file PROBLEMS (in the top-level directory when you unpack the Emacs source) to see if there is already a solution for your problem. Next, look for other questions in this FAQ that have to do with Emacs installation and compilation problems. If you'd like to have someone look at your problem and help solve it, see question 21. If you don't find a solution, then report your problem via e-mail to bug-gnu-emacs@prep.ai.mit.edu. Please do not post it to gnu.emacs.help or e-mail it to help-gnu-emacs@prep.ai.mit.edu. For further guidelines, see question 10.
