Question

I am using Scons to build my C project. I have an external linker file specified to ld using the -Xlinker flag. My problem is that whenever I change my linker script pointed at by -Xlinker, Scons does not take the change into account:

scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.

How can I force Scons to listen to changes to my linker script, and recompile the project when that linker script changes?

Answer 1

env = Environment()
env['LINKFLAGS']+=' -T linkerscript.lds '
Depends(program, 'linkerscript.lds')
