Only global functions and variables are placed in the OBJ PST table. Trying to access variables of the types below will often cause Unresolved Externals.

Static functions/variables

Functions declared with the static modifier by definition have file scope. Static variables have the same limitation. Trying to access any static variables from outside of the file in which they are declared can result in a compile error or an unresolved external depending on the specific coding of the source files.

MAIN.CPP

extern void func1(void);

void main(void)
{
 func1();
}

TEST.CPP

static void func1(void)
 {
  //Do something
 }
