I think this means that something went wrong when generating DerivedConstants.h, which is where the definition of bdescr_link() comes from. In my build, I have the following, in the file includes/dist-derivedconstants/header/: #define OFFSET_bdescr_link 16 #define REP_bdescr_link b64 #define bdescr_link(__ptr__) REP_bdescr_link[__ptr__+OFFSET_bdescr_link] This is auto-generated by the program in utils/deriveConstants. This used to be a C program, but nowadays it's a Haskell program that generates a C program for reasons that I forget. Anyway, your problem is somewhere in there... see if you can find out where by dumping out intermediate files and so forth. If you get stuck, tell us where you get to and we'll try to help some more.

I think this means that something went wrong when generating DerivedConstants.h, which is where the definition of bdescr_link() comes from. In my build, I have the following, in the file includes/dist-derivedconstants/header/:

#define OFFSET_bdescr_link 16 #define REP_bdescr_link b64 #define bdescr_link(__ptr__) REP_bdescr_link[__ptr__+OFFSET_bdescr_link]

This is auto-generated by the program in utils/deriveConstants. This used to be a C program, but nowadays it's a Haskell program that generates a C program for reasons that I forget.

are you using GCC or Clang, what versions are they? On Tue, Dec 10, 2013 at 4:43 PM, Alexander Pakhomov wrote:

I think you should look at includes/dist-derivedconstants/header/DerivedConstants.h first, look for the lines that I pasted in my email below. The problem is likely in there, but the file is automatically generated so you'll need to look at how it is generated. The program is in utils/deriveConstants.
