am trying to compile the body of a class that I got from my e-book after designing the header file but am getting this error message: [Linker error] c:/crossdev/src/mingw-w64-svn/mingw-w64-crt/crt/crt0_c.c:18: undefined reference to `WinMain@16' file: C:\Users\Chuks Joe\Desktop\collect2.exe Message:[Error] ld returned 1 exit status The header file is in a separate file called dice.h and the class body in another separate file called called dice.cpp. the client program is in a separate file too called testdice.cpp. Please help me with tips on how to arrange these files and where to put the so that they can all be linked together for my program to run.

some background. What is the linker? Consider the framework of a typical C++ program shown below. The main program in main.cpp uses a class called Type1, declared in the file type1.h-no executable code appears here-and defined, with executable code, in http://inst.eecs.berkeley.edu/~selfpace/studyguide/9F.sg/Output/linker.errors.html the file type1.cpp. A private class variable in the Type1 class is an object of https://www.cs.bu.edu/teaching/cpp/debugging/errors/ Type2, similarly declared in the file type2.h and defined in the file type2.cpp. main.cpp #include
Fatal Errors Logic Errors Note that the error messages shown below may be specific to our compiler/linker or machines. Nonetheless, other systems and compilers will provide similar information. Compiler Messages When the compiler is compiling your code (i.e., converting your code into instructions the machine understands), it will report problems that it finds in your code. Aside: Here, we are being technical and refer to compiling as the stage before linking. Linking is when all the compiled pieces of a program and the libraries it uses (e.g., for cin) are put together to form an executable. Often, compiling and linking together are just referred to as compiling. There are two severities of messages the compiler can give: Compiler Warnings A compiler warning indicates you've done something bad, but not something that will prevent the code from being compiled. You should fix whatever causes warnings since they often lead to other problems that will not be so easy to find. Example: Your code calls the pow() (raise to a power) library function, but you forgot to include math.h. Because you've supplied no prototype for the pow() function (its in math.h), the compiler warns you that it assumes pow() returns an int and that it assumes nothing about pow()'s parameters: somefile.cpp:6: warning: implicit declaration of function `int pow(...)' This is a problem since pow() actually returns a double. In addition, the compiler can't type-check (and possibly convert) values passed to pow() if it doesn't know how many and what type those parameters are supposed to be. Note: The compiler will label warnings with the word warning so that you can distinguish them from errors. Compiler Errors A compiler error indicates something that must be fixed before the code can be compiled. Example: You forget a semi-colon (;) at the end of a statement and the compiler reports: somefile.cpp:24: parse error before `something' Always remember to fix the first few errors or warnings, since they may be causing all the
