error using the loadlibrary function

I am getting a loadlibrary error on line 421, and cannot figure out why. I have microsoft visual c++ 2010 express, and windows jdk, so i should be good to go.

Also, if i compile a program that uses the 'loadlibrary' function into an executable, can computers w/out a c/c++ compiler still run the code?

We will need to see some of your log of the session. I have no idea at the moment what "line 421" refers to -- your line 421? Line 421 inside one of the Mathworks routines? And what error is occurring?

Which MATLAB version are you using?

If you use loadlibrary() with the name of a .h file, then that requires a C/C++ compiler at run-time. You can, however, create an information file that has all the necessary information, and you can compile that information into the executable and then the C/C++ compiler would not be needed at run-time. (My memory is telling me that you must use that form if you are building an executable.)

i am using 2011b. it errors out at line 421 of load library. looks something like this:

Error loading library intermediate output follows.
The actual error is at the end of this output.
*********

Failed to parse type '" C " struct TimeTag { unsigned long MilliSeconds ; unsigned short MicroSeconds ; short int JulianDay ; }' original input '" C " struct TimeTag { unsigned long MilliSeconds ; unsigned short MicroSeconds ; short int JulianDay ; }'
Found on line 133 of input from line 132 of file C:\\Users\\username\\Desktop\\folder\\HeaderFile.h

Then a whole bunch of errors that look like this:

C:\Users\username\Desktop\folder\libfun.h(542) : error C2143: syntax error : missing ')' before '*'

I am trying to simply do this in the command window. Do i have to do something else first?

[Walter Roberson]

Please show the code for 20 or so lines before and after line 132 of HeaderFile.h .

Is the library written in C or C++ ? Can you tell whether the .h file is written in C or in C++ ?

[ryan]

Also it appears that each error line occurs in the header file whenever a function returning a variable of type 'struct' is called. Could this possibly be a compiler isssue, i am using microsoft visual c++ 2010 express.
