I am seeing different behavior when a mex file is compiled using mbuild (as part of a larger MATLAB compiler project) as compared to when it is compiled individually using mex().
One way to include a mex file in the building of a standalone is to pre-compile it from the command line using the mex command and then to add the mex file manually to the list of dependent files. When I take this approach, mex() completes the compilation without errors and, when I run a project build, everything works fine and the resulting standalone .exe performs as desired.
If however, I replace one of the project's mex files, say linterpcpp.mexw64, with the source code file linterpcpp.cpp that it originates from and try to rebuild, mbuild() will run its own pre-compilation of linterpcpp.cpp as part of the overall process of building the standalone. This leads to to an error as follows,
Deployment\deployment\linterpcpp.cpp(140) : error C2664: 'mxCreateNumericArray_730' : cannot convert parameter 2 from 'int ' to 'const mwSize *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Error: An error occurred while shelling out to mbuild (error code = 9).
Unable to build executable.
I am confused because the file linterpcpp.cpp compiles fine when I do
>> mex linterpcpp.cpp
and I have only one compiler installed on the machine, Microsoft Software Development Kit (SDK) 7.1, so both mbuild() and mex() have to be using the same compiler C/C++ compiler.
Any ideas what's happening?
You can think of your watch list as threads that you have bookmarked.
You can add tags, authors, threads, and even search results to your watch list. This way you can easily keep track of topics that you're interested in. To view your watch list, click on the "My Newsreader" link.
To add items to your watch list, click the "add to watch list" link at the bottom of any page.
To add search criteria to your watch list, search for the desired term in the search box. Click on the "Add this search to my watch list" link on the search results page.
You can also add a tag to your watch list by searching for the tag with the directive "tag:tag_name" where tag_name is the name of the tag you would like to watch.
To add an author to your watch list, go to the author's profile page and click on the "Add this author to my watch list" link at the top of the page. You can also add an author to your watch list by going to a thread that the author has posted to and clicking on the "Add this author to my watch list" link. You will be notified whenever the author makes a post.
To add a thread to your watch list, go to the thread page and click the "Add this thread to my watch list" link at the top of the page.
The newsgroups are a worldwide forum that is open to everyone. Newsgroups are used to discuss a huge range of topics, make announcements, and trade files.
Discussions are threaded, or grouped in a way that allows you to read a posted message and all of its replies in chronological order. This makes it easy to follow the thread of the conversation, and to see what’s already been said before you post your own reply or make a new posting.
Newsgroup content is distributed by servers hosted by various organizations on the Internet. Messages are exchanged and managed using open-standard protocols. No single entity “owns” the newsgroups.
There are thousands of newsgroups, each addressing a single topic or area of interest. The MATLAB Central Newsreader posts and displays messages in the comp.soft-sys.matlab newsgroup.
You can use the integrated newsreader at the MATLAB Central website to read and post messages in this newsgroup. MATLAB Central is hosted by MathWorks.
Messages posted through the MATLAB Central Newsreader are seen by everyone using the newsgroups, regardless of how they access the newsgroups. There are several advantages to using MATLAB Central.
Your MATLAB Central account is tied to your MathWorks Account for easy access.
Use the Email Address of Your Choice
The MATLAB Central Newsreader allows you to define an alternative email address as your posting address, avoiding clutter in your primary mailbox and reducing spam.
Most newsgroup spam is filtered out by the MATLAB Central Newsreader.
Messages can be tagged with a relevant label by any signed-in user. Tags can be used as keywords to find particular files of interest, or as a way to categorize your bookmarked postings. You may choose to allow others to view your tags, and you can view or search others’ tags as well as those of the community at large. Tagging provides a way to see both the big trends and the smaller, more obscure ideas and applications.
Setting up watch lists allows you to be notified of updates made to postings selected by author, thread, or any search variable. Your watch list notifications can be sent by email (daily digest or immediate), displayed in My Newsreader, or sent via RSS feed.
