std::function/bind like type-erasure without Standard C++ library

Question

I\'m developing a simple event driven application in C++11 based on the publish/subscribe pattern. Classes have one or more onWhateverEvent() method invoked by the

Before I try to write all the STL stuff by hand, I try to use the STL which I already have from the compiler itself. Because most of the STL code you use is header only, I simply include it and do some minor hacks to get them compiled. In fact id did 10 minutes to get it ready to link!

I used avr-gcc-5.2.0 version without any problems for the task. I have no old installation and I believe it is easier to install the actual version in some minutes instead of fixing problems from the old one.

After compile your example code for avr I got link errors:

build-check-std-a520-nomemdbg-os-dynamic-noncov/main.o: In function `std::__throw_bad_function_call()':
/home/krud/own_components/avr_stl/avr_stl009/testing/main.cpp:42: undefined reference to `operator delete(void*, unsigned int)'
/home/krud/own_components/avr_stl/avr_stl009/testing/main.cpp:42: undefined reference to `operator delete(void*, unsigned int)'
collect2: error: ld returned 1 exit status

Simply write your own __throw_bad_function_call and get rid of the link problem.

For me it makes really no sense to write a own STL implementation. Here I simply used the headers which comes from the compiler installation ( gcc 5.2.0).
