So, this is a bit of a GNU Make mystery to me. If I have a failure for at
least one of the features, and if I leave out that DUMMY then I get this
printout:
... libperl: [ OFF ]
... libpython: [ on ]
... libpython-version: [ on ]
... libslang: [ on ]
... libunwind: [ on ]
... on-exit: [ on ]
... stackprotector: [ on ]
... stackprotector-all: [ on ]
GEN python/perf.so
Note how the last entry is missing: volatile-register-var.
If I add the DUMMY I get the full printout:
... libperl: [ OFF ]
... libpython: [ on ]
... libpython-version: [ on ]
... libslang: [ on ]
... libunwind: [ on ]
... on-exit: [ on ]
... stackprotector: [ on ]
... stackprotector-all: [ on ]
... volatile-register-var: [ on ]
GEN python/perf.so
Somehow GNU Make appears to be eating terminal ouput - or I might have
misunderstood something.
I hope it's the latter - but if it's the former then the DUMMY entry is
needed :-/
Thanks,
Ingo
