| Issue |
We want to initialize an array of PtWidget_t pointers as follows:
x09PtWidget_t *arrayname[3] = {ABW_name1, ABW_name2, ABW_name3};
The instance names are from an application created in PhAB. When compiling this, we get error message "expression must be constant".
What could be the problem?

| Solution |
ABW_xxxx pointers are assigned at application startup. This is why you are getting the "expression must be costant" error - because the values do not exist at compile-time. |
