Two errors concerning make distclean

[sschmidt]

Two errors concerning make distclean, they might be connected:

1. make distclean fails when executed in a freshly checked out svn, eg.

   svn co http://svn.hepforge.org/whizard/trunk . && autoreconf && ./configure FC=gfortran && make distclean
   

leads to

make[3]: Entering directory `/localscratch/sschmidt/whizard/temp2/src/omega/bin'
Makefile:810: ../src/Makefile.depend_fortran: No such file or directory
Makefile:811: ../src/Makefile.depend_ocaml: No such file or directory
make[3]: *** No rule to make target `../src/Makefile.depend_ocaml'.  Stop.
make[3]: Leaving directory `/localscratch/sschmidt/whizard/temp2/src/omega/bin'

2. If sourcedir and builddir are the same, consecutive execution of make && make distclean && make

   svn co http://svn.hepforge.org/whizard/trunk . && autoreconf && ./configure FC=gfortran && make && make distclean && ./configure FC=gfortran && make
   

leads to an error

9 output files written: vamp.1 .. vamp.9
Transcript written on vamp.log.
test -r vamppics.mp && mpost vamppics
This is MetaPost, Version 0.641 (Web2C 7.5.4)
(vamppics.mp
! I can't find file `feynmp'.
l.2 input feynmp

in the second run of make. (The first one works)
Comparing the trunk after check out and after make distclean, I noticed that after make distclean share/doc/manual.tex is missing while there are some dirs withadditional files compared to the state immediately after checkout.

Forgot to mention: Tested with r2383, so not solved by #306

[Juergen Reuter]

TO, maybe you could have a look on this....

[Christian Speckner]

First half fixed in r2387. Second half will follow... after lunch :)

[Christian Speckner]

Fixed in r2390.

For me, both sets of commands now give errors different from the ones above. Will ask CS about it.

As requested by CS: the error messages:

1: for make distclean on fresh svn

The first issue can't be fixed in any reasonable way. The reason is the automagic generation of dependencies, leading to the following chain of events on a make (dist)clean in a virgin tree from SVN:

1. make tries to include Makefile.depend -> fails

2. make tries to generate Makefile.depend -> requires tao_test.f90

3. make tries to generate tao_test.f90 -> requires ../src/f90.m4

4. because this is a virgin checkout and the SUBDIRS are preocesses in _reverse_ order on make (dist)clean, ../src/f90.m4 doesn't exist yet -> make fails with the above error message

However, this problem only affects _virgin checkouts_, once any makefile target different from (dist)clean has been processed, there is no "legal" way to get this error again (without deleting files manually). Therefore, I think the significant changes to the build systems necessary to avoid this are not worth the gain -> this part is "wontfix".

I agree w/CS's comment 100% ...

The second issue is fixed in r2393.
