Bug #: 52946
Summary: Unable to define a Block variable
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: lun...@gmx.de
when defining a 'block' variable using valid syntax (test.c):
#include <stdio.h>
int main (int argc, const char * argv[]) {
int (^myBlock)(int) = ^(int num) {
return num;
};
printf("Result is %d\n", myBlock(3));
return 0;
}
"gcc test.c" gives error message: "test.c:5:8: error: expected identifier or
‘(’ before ‘^’ token"
This compiles and executes correctly with gcc 4.2.
