Fatal error C1067: compiler limit: debug information module size exceeded

Error Message

When using the #import directive to include MO20.ocx, and the project is compiled in debug mode, the following error may occur:"Fatal error C1067: compiler limit: debug information size exceeded"

Cause

When the project is compiled in debug mode, two files are created in the output directory: Mo20.tlh and Mo20.tli. The error occurs because the declaration of "ProjectedCoordSysConstants" in Mo20.tlh is too large for the compiler to handle.

Solution or Workaround

• Method One:
  
  1. Copy Mo20.tlh and Mo20.tli to the same folder as the rest of the source files.
  
  2. Change the imports statement to include.
  
  

  Code:
  #include "mo20.tlh"

  
  
  3. Remove lines from the declaration of ProjectedCoordSysConstants until the project compiles successfully.
  
  

  Note:
  Be sure to remove only the constants the project does not need.

  
  
• Method Two:
  
  1. Instead of declaring a constant in the enum declaration, use:
  
  

  Code:
  const int $myCS = $myValue;
  

  
  
  

  Note:
  $myCS is the name of the constant and $myValue is the ID number for the coordinate system.

  
  
  2. When needed, use a typecast to convert the constants to the correct type.
  
  

  Code:
  static_cast<enum ProjectedCoordSysConstants> ($myCS);

  
  
• Method Three:
  
  Use exclude code on the #import to stop the enum from being imported.
