[Scons-users] Code generation and VariantDir?

[Jason Fritz]

Hi Dirk,

Thanks so much for your time/attention on this!

The setup you sent me has one serious difference from my setup: the
auto-generated foo.h gets copied to the variant directory.  In my setup,
the .h is generated within the same dir as the .tsn.  The reason I'm doing
it this way is for legacy reasons: I'm converting an old recursive
Makefile-based build system into SCons, and there are hundreds of
directories that are importing the header files from existing source dirs.
 I suppose I could re-work the build system to put the generated source
under the variant dirs if necessary, but would prefer not to.

Is there an easy way to get the .h file into the same dir but have the .o
files go into the variant dirs?

Thanks!!
Jason
