Re: [Mingw-users] Undefined reference to WinMain@16

[C. M. <cos...@gm...>]

Hi,
I thank all of you for attempting to help me.
I am reading a lot of documentation (really, more than I expect to).
By the way,I have found a code sample of a scrensaver, which contains
its own WinMain function. So, I have coded a simple code which invokes
a rather simple WinMain() function and 'g++ -c mycode.cpp', and then
'g++ -o mycode mycode.o' and, Eureka, it generates an executable,
without warnings nor errors!
So, I think that is the way. I am working now on writtimg a more
elaborated version of that WinMain() function, in order to instruct my
program in how parameteers must be read from the cmdline, and how the
rest of the program has to interpret them.
Of course, it implies more work but it will be worth!
On the other hand, we have to be carefull because there is a lot of
no-solutions in these forums, and not all what we find is really true,
and could lead us to non sense ways, as the '-lSDMain -lSDL -mwindows'
'solution', that I encountered which does not solve the problem at
all, mainly when I don't need Simple DirectMedia Layer at all!
Taking a positive actitude, those comments make me learn about SDL and
other interesting things!
Thanks,
Markanikoff
