--- Comment #13 from David Edelsohn <dje at gcc dot gnu.org> 2012-11-06 14:46:34 UTC --- > Because if you have a function declared as inline in a header file that gets propagated to multiple source files is ok, but in my case that inline keyword was removed by some $ifdef LINUX and so I end up with having the constructor body defined in the header like this: ClassA::ClassA(){//body}. Now because this is in the header it will propagate to all sources that includes it. So finally I end up with that constructor in multiple constructors sources. This would not happen if the inline keyword have not been removed from it. This was a bug in our code and I removed it. Okay, so the problem was *lack* of inlined constructors. Now that makes more sense. > Our project has one exe and several shared and static libs. To make the things easier I moved every source file in the exe. Now the problem I have is with the order of the initialization of global objects that reside in multiple object files. I need objects in a source file by constructed first before any other objects in the rest of the files are constructed. If you actually create shared libraries, you should add -fPIC to the compilation command. This also adds some additional uniqueness to symbols. > You said that I can decorate the constructors with a priority. How to do that ? Before migrating from xlC we used #pragma priority. This is ignored by gcc. We also used -qpriority flag of xlC. Also gcc does not have something like this. Or? Use __attribute__ ((init_priority (NNNN))) http://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Attributes.html
