GCC header caching

[Nosferatu]

<br>I've passed away... to linux, for some time, and i'm working on a very (VERY) big project, which contains about 15 Megs of code. <br><br>I have this HUGE timing problem... In windows, i used BC 5 compiler, and it does some caching (precompiled headers), a thing absolutely unknown to me in gcc RedHat Linux distributions. Therefore, when i HAVE to compile the big part of the project - which is some 90% of all- i have to wait some... 4-5 hours for the job to be done, of course, if i modify some project headers, that because for every source file, all the headers are recompiled. <br><br>So, does anybody know some linux C compiler or some gcc options that tell him&nbsp;&nbsp;NOT TO RECOMPILE ALL THE HEADERS for each tiny file???? I know that only the &quot;specific_file.c&quot; dependent headers are recompiled, but... that's not enough.<br><br>Thanx.<br>
