We modify these all the time from .ecm scripts, so there must
be some other problem at work here.
If you modify these values, do you see them if you export the
configuration? e.g.
% ecosconfig export cfg
The file 'cfg' should show the modified values.
It does.
Of course, don't forget to rebuild your build tree after making the
changes. Using the CLI
% ecosconfig tree
Until you do this step, only the configuration database changes, not
the actual build. This includes the "include" files used by the sources
to get at the actual values.
Yes, I know.
The problem may be that I'm not using the commandline tool (ecosconfig),
but the GUI Configuration tool "2.12 net" for Windows (configtool.exe).
Maybe it fails to correctly create the build tree? (I tried deleteing the
old buildtree to be save, even restarted the tool itself, and tried
different tool versions).
There are a few issues to resolve, before I can actually do the complete
build on my NT system using the commandline ecosconfig, e.g. the
target-specific toolchain is not in the path (for other reasons). Do you
think it is worthwhile to turn away from the GUI tool and use ecosconfig
instead?
All the best
Peter
