This appears to be https://github.com/ldc-developers/ldc/issues/544.

Patches would be greatly appreciated, since I can't easily upgrade my MacBook to Mavericks (the installer chokes on the MBR/GPT partition table combo present on its disk), and I don't think Kai has a working 10.8 setup either.

If you just want to use LDC, you can just comment out the offending line, as it only affects debug log output (-vv).

That is definitely the case.

I have a MacBook running Lion (10.7.5) which refuses to upgrade to
Mountain Lion and hence Mavericks (10.9.1), so I'll try building on
there to ensure I can.

Seems like a feasible workaround :-)

If I get a chance over the next few days I'll see if I can suss out something more permanent as a fix.

Thanks.

This thread of timely. However I am running 10.8.5 Mountain Lion.

I ran into the same compiler error tonight after switching my LDC compile from gcc-4.8 to system clang with -stdlib=libc++ so it will use libc++ instead of libstdc++.

I think the error is that template in logger.h uses operator<< for ostream& which is not defined when instantiated.

This worked for me,

--- a/gen/logger.h
+++ b/gen/logger.h
@@ -15,7 +15,8 @@
 #ifndef LDC_GEN_LOGGER_H
 #define LDC_GEN_LOGGER_H

-#include <iosfwd>
+//#include <iosfwd>
+#include <ostream>

 namespace llvm {
     class Type;

I'll bet libstdc++ headers pulled in more classes and avoided the error.

Now I it looks like I have to build libconfig++ against libc++ too (macport libconfig-hr uses libstdc++). I am getting an ldc2 link error. Oh well.

I can't remember what the problem was, but it certainly seemed to work fine yesterday.

The work-around was to include iostream. But it was applied only
to master branch. I merged it yesterday into the other
branches....
