Comment 3 by mazdak@chango.com: Just a note that OS X Mavericks (10.9) GM was released today. |
I reproduced this on my non-Mavericks machine. g% sw_vers ProductName: Mac OS X ProductVersion: 10.8.5 BuildVersion: 12F37 g% xcodebuild -version Xcode 4.5.2 Build version 4G2008a g% It is the same problem (an inner anonymous struct/union) as issue #6472. That fix makes this work too. Status changed to Duplicate. Merged into issue #6472. |

Comment 6 by mazdak@chango.com: Is there a fix for issue #6472? I wasn't able to see a fix there. Setting CC=gcc will not work on Mavericks as gcc no longer ships with OS X 10.9 |

On OS X 10.9 Mavericks, when building the following code snippet, I get the following error: # command-line-arguments xxxx.go:190:12: struct size calculation error off=40 bytesize=32 The same go file (which is actually a cgo file) works on older versions of OS X and Linux. To assist, here is a snippet that reproduces the above problem: ---------- package main /* #include <stdlib.h> enum ct { A = 0x00, B = 0x01}; typedef enum ct ct; typedef struct cobject_s { enum ct type; size_t sz; union { char *str; // note for str: sz is strlen (not strlen+1 void *blob; int64_t i64; // easiest to have one large int type } u; void *free; // if this is set, this must be freed on destructuion } cobject; typedef struct cbin_s { char bin_name[32]; cobject object; } cbin; */ import "C" func main() { var a C.cbin }The text was updated successfully, but these errors were encountered:
