[Scons-users] Implicit cache error after running a successful build

[Rob Deckers]

Dear Matías,

I am also working on a Astyle tool for SCons.

My sersion works for a normal build, but not yet for the -interactive build.
I am very interested in how you solved this problem.

Kind regards,
Rob Deckers

Subject: [Scons-users] Implicit cache error after running a successful build

Hello list.
I have a Builder to run Astyle (http://astyle.sourceforge.net/) to my builds.
Thing is recently I've started getting this message when I try running it:

scons: Reading SConscript files ...
Install information:
    bin dir    : /home/matias/Proyectos/fudepan-build/install/bin
    lib dir    : /home/matias/Proyectos/fudepan-build/install/libs
    headers dir: /home/matias/Proyectos/fudepan-build/install/includes
    doc dir    : /home/matias/Proyectos/fudepan-build/install/docs
scons: done reading SConscript files.
scons: Building targets ...

=== Running ASTYLE ===

Inalterado  /home/matias/Proyectos/fudepan-build/projects/biopp/src/bio_molecular/bio_molecular.cpp
Inalterado  /home/matias/Proyectos/fudepan-build/projects/biopp/src/bio_molecular/triplets.cpp

Inalterado  /home/matias/Proyectos/fudepan-build/projects/biopp/biopp/biopp.h
[astyle] OK on: /home/matias/Proyectos/fudepan-build/projects/biopp
scons: *** [biopp:astyle] Implicit dependency `projects/biopp/bio_molecular.H' not found, needed by target `biopp:astyle'.
scons: building terminated because of errors.

As  you can notice, the process run OK but this error pops up after the astyle is done running.
I've followed the traceback and it rises somewhere in jobs.py:


> /usr/lib/scons/SCons/Job.py(227)start()

    226                 # build to stop if that's appropriate.

--> 227                 task.failed()
    228             else:

ipdb> n
scons: *** [biopp:astyle] Implicit dependency `projects/biopp/bio_molecular.H' not found, needed by target `biopp:astyle'.

Which is relevant as the offending file (projects/biopp/bio_molecular.H) exists in my source but with the appropriate lowercase h and after following the traceback I don't see where the path gets mangled.
So my question is: What is this "implicit dependency" thing, how it works and how do I get it to tell me what is happening with my files?

Thanks in advance.
