When you mass compile VIs, LabVIEW verifies the existence of any subVIs and relinks the subVIs to the main VI. Relinking subVIs to the main VI decreases loading time because LabVIEW does not have to search for those VIs. LabVIEW also updates VIs to the version of LabVIEW you use. LabVIEW detects and reports corrupted VIs, which LabVIEW cannot load. If LabVIEW locates corrupted VIs, you can restore them from a backup.
Certain circumstances, such as upgrading a VI to a newer version of LabVIEW, require LabVIEW to recompile a VI when the VI first loads. LabVIEW continues to recompile the VI each time the VI loads until you save the VI. If you expect LabVIEW to recompile many VIs on load, you might want to compile and save all the VIs at the same time to avoid these tasks at a later time. When you simultaneously compile and save a collection of VIs, you are mass compiling the VIs.
Complete the following steps to mass compile a directory of VIs or an LLB.
|Note If you receive messages under the Status tab, open the VI listed. If the VI has an error, fix the error in the VI before trying to mass compile again.|
When you mass compile VIs, the Status tab of the Mass Compile dialog box displays a log of warning messages for the mass compile operation. For example, the log can report corrupted VIs and VIs that were loaded from the search directories instead of the path specified in the calling VI. You can mass compile to detect unexpected behavior in VIs you compile, such as VIs that break or load from unexpected locations.
You also can use the Mass Compile method to load and compile VIs in a directory programmatically.
LabVIEW mass compiles only VIs last saved in a previous version of LabVIEW and VIs with unsaved changes that would result in a recompile when you open them. When LabVIEW mass compiles a directory of VIs, it processes files in the following order at each level of the directory hierarchy:
