Deployable archive data is automatically embedded directly in compiled components and extracted to a temporary folder.
Automatic embedding enables usage of MATLAB® Runtime Component Cache features through environment variables.
These variables allow you to specify the following:
Define the default location where you want the deployable archive to be automatically extracted
Add diagnostic error printing options that can be used when automatically extracting the deployable archive, for troubleshooting purposes
Tuning the MATLAB Runtime component cache size for performance reasons.
Use the following environment variables to change these settings.
| Environment Variable | Purpose | Notes |
|---|---|---|
| MCR_CACHE_ROOT | When set to the location of where you want the deployable archive to be extracted, this variable overrides the default per-user component cache location. | Does not apply |
| MCR_CACHE_VERBOSE | When set to any value, this variable prints logging details about the component cache for diagnostic reasons. This can be very helpful if problems are encountered during deployable archive extraction. | Logging details are turned off by default (for example, when this variable has no value). |
| MCR_CACHE_SIZE | When set, this variable overrides the default component cache size. | The initial limit for this variable is 32M (megabytes). This
may, however, be changed after you have set the variable the first
time. Edit the file .max_size, which resides in
the file designated by running the mcrcachedir command,
with the desired cache size limit. |
You can override this automatic embedding and extraction behavior by compiling with the Overriding Default Behavior option.
If you run mcc specifying conflicting wrapper
and target types, the deployable archive will not be embedded into
the generated component. For example, if you run:
mcc -W lib:myLib -T link:exe test.m test.c
test.exe will not have the deployable
archive embedded in it, as if you had specified a -C option
to the command line. To extract the deployable archive in a manner prior to R2008b,
alongside the compiled .NET assembly, compile using the mcc's -C option.
You might want to use this option to troubleshoot problems with the deployable archive, for example, as the log and diagnostic messages are much more visible.
