[Scons-users] Windows resource files and variant builds

[Tom Tanner]

The problem is that the .res file contains a path to a .dll, which when 
the resource is compiled, causes rc to attempt to read the dll. And the 
dll in question is part of the build of this project.

And with a variant dir, you're doing the build from above where the 
files get stored, so ..\\..\\etc points to outer space.

In order to get the rc file to be compiled, you need to specify 
something like

IDR_LOADER_DLL         BINARY   MOVEABLE  PURE    "<variant 
dir>\\otherModule\\otherModule.dll"

which I have at eventually got round by doing

IDR_LOADER_DLL         BINARY   MOVEABLE  PURE    DLL_TO_USE

and setting  RCFLAGS like this

other=env.File(os.path.join('..','..','otherModule','otherModule.dll'))

env.AppendUnique(RCFLAGS=[ '-DDLL_TO_USE="\\"%s\\""'%other.abspath ])

and it needs all those double quotes and backslashes! But it'd be nice 
if I could get a 'path relative to where the SConstruct file is' somehow 
as that .abspath works out as something depressingly long.
