As expected, it failed...
Here is the ls -l output before the build attempt:
-rw-rw-r-- 1 jon jon 5239 Sep 29 20:28 XmPrivate.h
-rw-rw-r-- 1 jon jon 1794 Sep 29 20:28 extractprototype.awk
Timestamps are the same (not sure if seconds count), but whatever, an
attempt is made to rebuild it anyway.
Here's the relevant snippet from the build log:
...
including in include/Xm...
/home/jon/src/CDE/cde/include/Xm
make[3]: Entering directory `/home/jon/src/CDE/cde/include/Xm'
awk -f extractprototype.awk ../../imports/motif/lib/Xm/*.h > XmPrivate.h || rm
-f XmPrivate.h
awk: cannot open ../../imports/motif/lib/Xm/*.h (No such file or directory)
+ mkdir -p ../../exports/include/Xm
+ cd ../../exports/include/Xm
+ rm -f XmPrivate.h
+ ln -s ../../../include/Xm/XmPrivate.h .
...
Since the includes don't exist, extractprototype.awk fails, and then
the '|| rm -f XmPrivate.h' deletes it.
I have committed a patch that will prevent this from ever being
generated automatically in the future, simply by removing the
dependancy on extractprototype.awk for XmPrivate.h.
To rebuild manually,
cd include/Xm
rm XmPrivate.h
make XmPrivate.h
Sorry, but that's the way it's goingto have to be.
