Hmm, let&#39;s see ...

1. I created a sample project to see if I would get the same problem.

2. I looked in the objdump file if the symbol was indeed defined (it was)

(If you want to know anything about an elf (file format used by gcc) executable/object file look at it with objdump)

3. I googled &#39;heap_end&#39;. a promising hit &#39;told&#39; me that heap_end was defined by the c-library.

4. I searched the c-lib sources in my local filesystem for &#39;heap_end&#39;

(I didn&#39;t use the explorer for that. I did use a program that searches the content of all files for &#39;heap_end&#39;).

5. Voilá, file found => static definition.

6. I know that static symbols are visible only in the current file.

You know, experience is difficult to explain...
