[Coin-discuss] externals

[Matthew Galati]

Ok. 

I had done .../<proj>/trunk instead of .../<proj>/trunk/<proj>. The latter is what I wanted. 

Thanks Stefan and Ted.

not a solution, but maybe a workaround:
Instead of checking out the package base directory (e.g., https://.../svn/Cbc/trunk), you can checkout from the project base directory (e.g., https://.../svn/Cbc/trunk/Cbc). This has no externals defined and will be sufficient in most cases.
Then you define the externals for your project X such that all externals for projects A and B are satisfied, i.e., such that you get C (once).
See, e.g., the externals for the Bonmin project.

But should svn not recognize it if A and B point to the same C (i.e., same revision number)?
