<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I noticed that build2 doesn’t compile file-a.c when an included header file i.e. file-a.h is changed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">It would be very helpful if this would be supported by build2.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">If along source file changes only a header file is changed this quickly becomes a problem if the build is executed but it actually didn’t compile everything that would be necessary
to make a wholesome incremental build. And when you are using automatic .c and .h file generation this can be a pretty common problem.

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">With make it’s absolutely not simple but at least possible to trigger compilation based on changed contents of a header file (i.e. based on a md5 hash).

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I know build2 is not feature complete and I’m asking for some pretty advanced stuff here. Just want to make you aware of some corner use cases.
