Root6.06.08 on Mac Os X, dyld: lazy symbol binding failed when creating TF1


I’m linking agains root 6.06.08 on Mac Os X 10.11.6 and compiling with:

I can compile and my code is working up until the following line 72. “ivec->name” is a simple std::string in a struct". However, when I try to create the TF1 I get the error message beneath:

Before I switched to Mac os X I was running my code on a Linux machine without problems. However, I change stuff in the overall code, nothing related to the shown section though.

Any ideas?


  • when linking against root 6.06/02 the code is running without any problems
  • when linking against root 6.08/00 and 6.08/02 the code is showing problems way earlier

When calling the two 6.08 versions:

this is resulting in a some random histogram that got nothing to do with the one in the file and only has one bin. But I can access it and use it.

So what is going on?
