hello again... Could somebody tell me if to use C++ custoum templates i must use the stdlibc++? thanks in advance Tiago J.

As far as I know C++ templates do not need any support from the stdlibc++. Just make sure that you compile your C++ code with -fno-rtti and -fno-exceptions. Frank -- ## Dept. of Computer Science, Dresden University of Technology, Germany ## ## http://os.inf.tu-dresden.de/~fm3 ##

thank you again for your prompt answer... I already compile with those flags. My problem is the following: because i'm using the dielibc i can't use STL, because it launches exceptions. So, i've made my own templates of vector and map without exceptions and i'm trying to use them. the error is the following: FailureDetector.o(.eh_frame+0x11): In function `map<int, heartbeat>::del(int)': /home/tiago/l4/pkg/failuredetector/server/src/WOO_map.h: undefined reference to `__gxx_personality_v0' main.o(.eh_frame+0x11): In function `main': /home/tiago/l4/pkg/failuredetector/server/src/WOO_vector.h:20: undefined reference to `__gxx_personality_v0' collect2: ld returned 1 exit status by the way, line 20 is the constructor and it doesn't throws exceptions. So here i am stuck at this point :( thanks again Tiago Jorge

Templates almost universally rely on exceptions, because operator new is specified as allowed to throw an exception. Regrettably, support for that is in stdlibc++. On Tue, 2005-03-15 at 13:03 +0100, Frank Mehnert wrote:

I can't find where the use of templates would imply the use or require the existence of the new operator. We happily (ab)use templates in L4Ka::Pistachio without any new operator or support for C++ exceptions. Uwe

sure... it works now... when i say templates i'm referring to a template made by me... not the templates from the STL. Those use on exceptions from the beggining, and because i use dielibc, i can't use them Tiago
