Bug ID: 21626
Summary: clang failed to compile Objective-C++ code with
-fmodules
Product: clang
Version: trunk
Hardware: PC
OS: MacOS X
Status: NEW
Severity: release blocker
Priority: P
Component: Modules
Assignee: unassignedclangbugs at nondot.org
Reporter: 191919 at gmail.com
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
clang svn (clang version 3.6.0 (trunk 222512)) failed to compile the following
trivial code when compiling it as Objective-C++ code:
```
#import <Cocoa/Cocoa.h>
int main() {
}
```
The command line to compile it was:
$ /opt/bin/clang++ -fmodules -c -o m m.mm
It gave a huge bunch of error messages:
