make extra-distcheck broken

[Juergen Reuter]

One of the last commits broke make extra-distcheck. Have to see what it is :(

[Juergen Reuter]

Oh no, it is a race condition :((( {{{make[5]: Nothing to be done for `all-am'.

Fatal Error: Can't open module file 'kinds.mod' for reading at (1): No such file or directory make[4]: * [limits.lo] Error 1 make[4]: * Waiting for unfinished jobs.... }}} Seems it is not sufficient to check for .lo files, but one most really check for .mod files.

So the problem seems to be the stamp mechanism. That is switched off when noweb is switched off. Now the files are still built in order but apparently the compilation takes to long and kinds.mod is not ready when limits.f90 compilation needs it. I have no clue why this problem is showing up right now, but it is on the MAC with 4.9.0 and the DESY cluster with 4.6.3. To my best knowledge nothing fundamental changed...

[Juergen Reuter]

Next step: it only happens with make -j on the Macbook. make up to -j4 worked. Hm, what now?

[Juergen Reuter]

Muharhar, lavi in innocentia manus meas. It was commit #4639, introducing a dependence of limits.f90 on kinds.f90 which has not been added to the dependencies in src/misc/Makefile.am. Happily closing.
