Linker Tools Error LNK1270

  • Article

invalid file; timestamp does not match file linked with /LTCG:PGINSTRUMENT

The same files passed to the linker when specifying /LTCG:PGINSTRUMENT must also be passed when specifying /LTCG:PGOPTIMIZE.

/LTCG:PGOPTIMIZE requires that the inputs be identical to the /LTCG:PGINSTRUMENT phase.

To resolve this warning, run /LTCG:PGINSTRUMENT, redo all test runs, and run /LTCG:PGOPTIMIZE, or, create the optimized image with /LTCG:PGUPDATE instead of /LTCG:PGOPTIMIZE.
