compiling discrepencies

this is driving me crazy

in devc++ i'm NOT creating a project. I'm compiling w/ -ansi -pedantic -Wall -Wextra -Werror
if i have a class in a header file like so:

Code:

---

template <typename T> class myClass
{
    public:
        myClass();
        ...
};

---

and define the constructor in a source file like so:

Code:

---

template <typname T> myClass<T>::myClass<T>()
{
    ...
};

---

it works just fine.


But when I compile the same stuff in cygwin w/the same options, it tells me I have undefined references to my constructors.

WTF???

BTW, here's my makefile for gcc:

Code:

---

COMPILECPP=g++
FLAGS=-g -DDEBUG -ansi -Wall -Wextra -pedantic -Werror
CPPSRC=$*.cpp
BUILDCPP=$(COMPILECPP) $(FLAGS)
BUILDMAINCPP=$(BUILDCPP) -o
.SUFFIXES:
.SUFFIXES: .c .cpp .h .o
.cpp.o: ; $(BUILDCPP) -c $(CPPSRC)

all: List

clean:
        rm -rf *.o a.out
       
List: Driver.o List.o SysCalls.o
        $(BUILDMAINCPP) List Driver.o List.o SysCalls.o

SysCalls.o: SysCalls.cpp SysCalls.h
 
List.o: List.cpp List.h

Driver.o: Driver.cpp List.h SysCalls.h

When writing template classes, do not separate the class declaration from its implementation. Read: Why can't I separate the definition of my templates class from it's declaration and put it inside a .cpp file?.

oh oh oh OK. yea i've heard that before. because *templates* aren't treated the same as
a *non-templated* class. you're the coolest!

so the whole:

Code:

---

template <typename T> myClass<int>::myClass<int>();

---

acts as a prototype of sorts?
