Could anyone tell me from where could I get the c compiler source code.In particular the lexical analyzer for c.I searched the web but no links show how a compiler is defined.

search the web: "c compiler" source

By the way, You can find source code for any free software or open-source software, and a licence allowing you to use it freely.

C being the implementation language for Unix, I would expect it to have been one of the first pieces of software with available source, and a copyleft licence.

When searching the web for the source code of a piece of sofware, look for these types of licences (without a licence you are not allowed to use the source code anyway). Creative Commons licences will generally do too, and non copylefted free licences such as BSD licences. All these terms are usually useful keywords to find software with source code available.

  • $\begingroup$ @Raphael Sorry. The question looked so silly, I forgot it was off topic. That is for my first sentence. Then some old reflexes took over. Maybe it can be moved to a more appropriate place. Should I delete? $\endgroup$ – babou Sep 22 '14 at 18:38
  • $\begingroup$ Nah, it might be helpful to someone (until the whole question is deleted automatically). $\endgroup$ – Raphael Sep 22 '14 at 19:27
