[Scons-users] problem copying files to variant directory

[Jean-Baptiste Lab]

The issue is that you are installing the oneA.h and oneB.h headers in
the build directory of mods/one in the *same* place SCons would copy
them over if you had "duplicate=True"

I'm guessing you want to put the headers of both "one" and "two" in
common one place ?
If so, change your Install() calls from:

env.Install("include", incls)

to:

env.Install("<an absolute path not ending up being the path where SCons
would install stuff>", incls)

or, for a shorter, working example:

env.Install("#include", incls)

(that would install the headers in a new "include" directory at the same
level as your SConstruct).

Hope this helps,
