Unions Not Supported

Postby paul.shubert » Thu Dec 12, 2013 6:01 am

Unions do not appear to be supported. i.e. the following declaration:

Code: Select all

union Vector3 {
  int r[3];
  struct {
    int x;
    int y;
    int z;
  } s;

Vector3 vector;

Results in a 3x integer array named "r" when implemented in an Arduino ".ino" file, along with the error:
Sketch Error - unknown declaration union Vector3 {
Line: -1 union Vector3 {

When included in a library (#include) file.

Which would also imply that "struct" is also not supported?

Thanks for pointing this out. Unions and structures are supported but the memory overlap which unions use will be implemented later.

The code above will work and run in version 0.99D due out shortly. Thanks

Return to “Version 0.98”
