I'm using a user-maintained makefile, and I add a copy command as a custom post build step:
copy \sw\dev\gpu_drv\bugfix_main\_out\%B\nvwgf2um*.* \sw\dev\gpu_drv\bugfix_main\_out
This works fine on version 17, but doesn't work on version 18.
To test this, I added:
echo foo %B
as a prebuild and a post build step. The echo executes in the prebuild step, but not in the post build step.
So back to version 17 I go for a while, I guess.
