Overriding Default CTF Archive Embedding for Components Using
the MCR Component Cache
As of R2008b, CTF data is automatically embedded directly in MATLAB Builder EX components
by default. In order to extract the CTF archive manually, you must
build the component using the mcc-C option.
If you do not use the mcc-C option
to specify that a separate CTF file is to be generated, you can add
environment variables to specify various options, such as:
Defining the location where you want the CTF archive
to be extracted
Adding diagnostic error printing options that can
be utilized when extracting the CTF, for troubleshooting purposes
Tuning the MCR 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 CTF archive
to be extracted, this variable overrides the default per-user component
cache location. | Not applicable |
| MCR_CACHE_VERBOSE | When set, this variable prints details about the component
cache for diagnostic reasons. This can be very helpful if problems
are encountered during CTF archive extraction. | Not applicable |
| 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. |
Note
If you run mcc specifying conflicting wrapper
and target types, the CTF will not be embedded into the generated
component. For example, if you run: mcc -W lib:myLib -T link:exe test.m test.c
the generated test.exe will not have the CTF embedded
in it, as if you had specified a -C option to the
command line. |
Caution
Do not extract the files within the.ctf file
and place them individually under version control. Since the .ctf file
contains interdependent MATLAB functions and data, the files
within it must be accessed only by accessing the .ctf file.
For best results, place the entire .ctf file under
version control. |
