An error occurred when reading profile-guided optimization data. This error can appear in several forms:
Reading 'filename.pgd' : 'PGD version is not supported (version mismatch)'.
PGD files are specific to a particular compiler toolset. This error is generated when you're using a different compiler than the one used to create filename.pgd. The error indicates this compiler toolset can't use the data from filename.pgd to optimize the current program. To resolve this problem, regenerate Filename.pgd by using the current compiler toolset.
Reading 'filename.pgd' : 'PGD file is read-only'.
This error is displayed when the PGD file is marked read-only on the filesystem. To resolve this problem, change the file attributes to read-write.
