function rt_lookup( ) undefined - c

I used Real time workshop to generate c code from a simulink model. When I tried to compile the resultant C code, I get the above error. When I check in the MODEL.c file, the function rt_lookup is called, but not defined.
After some research in google, I found that lookup tables are used if your model has subsystems.(Yes my model has some subsystems) but no information on this error.
I believe this function is defined in some library file. Any inputs regarding this is really helpful. Thanks in advance.

what library does LED belong to in Pspice?

I am a student and new to Pspice, I am given the following example circuit
and asked to created the following circuit,
which I have this
I think I have my circuit designed correctly. However, I am having trouble with finding the correct diode. I have tried different library such as diode, ediode, diode_bridge, on_diode and infineon, but the diodes from these library don't give a current of 20mA(typically lower than that). I also tried to find discrete.olb, however it's not in my capture library.... Is there any other library contains the 2legs led like the diodes in example circuit?I think the reason why I am not getting 20mA is because of the diode?
As can be seen here on the PSPICE website, you should be able to find all of the LED models in the Optoelectronics->LEDs library.

Method 'DUMPSETSET_GET_ENTITYSET' not implemented in data provider class

I created a function module and gateway service that reads data from SNAP_BEG table which is stores DUMP issues. There is no any error except that.
When I try to use link as /DumpsetSet I get
"Method 'DUMPSETSET_GET_ENTITYSET' not implemented in data provider class"
I found that how to redefine implementation but what code should I write in it? I cant find an example for this. Function module code is.
SELECT * FROM SNAP_BEG INTO TABLE ET_SNAP_BEG.
Or I just need to use something else?
What type of link should I use. I got one more project someoneelse done and I cant see difference in implementation from mine.
Edit: I can get firs record that program find by /DumpsetSet('username'). But it is not giving me all datas anyway.
Did you map the GetEntitySet to a data source from SEGW - SAP Gateway Service Builder, under the Service Implementation part. After this operation you should generate runtime objects.
There is a good blog for this, here.

Simulink C-Code Generationed logic

simple question here. I would like to examine the generated c code after it has been generated from Simulink. The problem is, I cannot find any of the logic code, or variables from the model. I've looked through the internet for a solution, but there's nothing that really points me in the right direction. Can anybody elaborate on what kind of structure is used when creating auto-generated c code from Simulink? I'd like to look at how the actual logic was created. I made a simple comparison model with three inputs and an or block, and a to-workspace block. Any help is greatly appreciated.

Writing a file with a fixed and variable part C

I have the following question:
The calendar text file and binary file should have a name that with a fixed part and a variable part. Use the time function (in time.h) or some other automatic mechanism to make sure that, when you write the files back out after updating the calendar, you do not overwrite the files you read in but you write a new version of the file that is clearly more recent.
Knowing that I have a program that manages a calendar.
Is it possible to to create a file with a fixed part and a variable part using the time.hlibrary ?
Thank you in advance!
Your question is vague, so the answer could only be similar.
From your specification, I guess you need a filename, f.e. "calendar-YYYYMMDDhhmmss.bin" and "calendar-YYYYMMDDhhmmss.txt"
When you "man time.h", you can see, that the time-"library" provides all these data. At the bottom of the man-page you see some related functions like "time()" and "strftime()", which help you to get a timestamp and to format a time to your needs.
If you "http://www.whathaveyoutried.com" and are stuck again, please update your question, and we will help you further.
EDITH (to the comment):
That depends on whether you should have a lot of files with each containing one "calendar" and the most recent dateded file is the actual calendar and the olde ones are backups; or you have one calendar-file with a new section for each "calendar", then you have to define (for yourself) how to organise these actual and historical sections.
as a matter of fact i would prefere the first solution, so each time you update your calendar, you call "fopen(path_filename_timestamp_txt, "w");". In the second case you would call "fopen(path_filename_txt, "a");" and "fwrite(timestamp);" your section-header;
Please show us, what you have done so far! (as short as possible, according to http://sscce.org/)

Leopard Console logs for common files reference

I am using plugins for one of my Mac OS X(desktop) application. These plugins refer to a common file that contains base class implementation of both the plugins.
When the application refers to this common base class, the following message is displayed in the console by the system:
" is implemented in both and . One of the two will be used. Which one is undefined."
This console message is displayed from 10.5.x onwards.
However this does not cause any problem. But, I do not want my class name to be printed in the console. Can someone help to avoid this console message.
A possible way around is to #define the name of your class as something unrelated, so that it remains the same in your code, for your use, but is obfuscated in the executable.
I'd like a neater solution myself. I have searched quite a lot, and it seems that in general console messages are for solving problems, rather than for looking for them, and more specifically that this kind of message isn't really an issue.
One can also use an EXPORTED_SYMBOLS_FILE or an UNEXPORTED_SYMBOLS_FILE (these are the relevant build setting names) to state which symbols you do or don't want to export. Often, you want to export at least one, but it can reduce the number of names that are revealed.
