I've looked at this now and couldn't reproduce this here (within 5
minutes of running cmake; make (aborting after generation of the
parser); rm -rf *). Also the only files outside the parser dir that
use phpast.h are part of targets that won't be built before the parser
library as they depend on it. So I'm guessing that something with the
generated dependency information from cmake is wrong, if anybody feels
like uploading his build-tree (from a broken make -j3) somewhere I'd be
willing to take a peek.

Nonetheless I did a small change to the macro for the generation of the
parser code in kdevelop-pg-qt's master branch. The ast.h file is now
part of the source file list. This means its listed as source file when
creating the kdev4phpparser target, which is a good thing according to
the cmake documentation:

"A target created in the same directory (CMakeLists.txt file) that
speci‐ fies any output of the custom command as a source file is given a
rule to generate the file using the command at build  time"

As I said, I couldn't reproduce it without the change either, so no idea
wether it fixes anything or not. Other than that I can't see any
problems with the cmake code related to missing dependencies.


If you stand on your head, you will get footprints in your hair.
