Question

The following code:

   if (!(ep = engOpen("\0"))) {
      fprintf(stderr, "\nCan't start MATLAB engine\n");
      return EXIT_FAILURE;
   }

Gives:

Can't start MATLAB engine

I don’t know what is the reason … I have two versions of Matlab R2011a 64-bit, and R2010b 32-bit. I use engine lib of second version of matlab. OS windows 7 x64.
According to some topics this problem can be caused by multiple matlab versions
MATLAB Engine Windows 7 problem
but i have deleted x64 Matlab from PATH enviroment variable…

Answer 1

A few things to try:

• Make sure your PATH is set to have the full path of the Matlab binary directory. For example, 64bit matlab this is C:\Program Files\MATLAB\R2011a\bin\win64. I’m not sure why you have two copies of 2011a, but I would confirm that only one install of matlab is on the current path.
• Make sure you are using a 32bit compiler when using 32bit matlab, and 64bit compiler when using 64bit matlab. This is very important.
• Confirm you are using a compiler that is supported
• Try re-registering the Matlab COM. I’ve had to do this for a 2010/2011 install.
  • On linux, make sure csh is installed.
