How the heck does SDL_rotozoom work?

SDL Development

Hello everyone!
Alright, I copied the SDL_rotozoom.c and SDL_rotozoom.h files to my
include dir, but it told me that _rotozoomSurface() was unresolved…
There was no .DLL nor .LIB file, so I looked it up in Google and I found
a project file, and it generated those… I tried compiling my program
(game), but it behaved weirdly:

  1. My EXE was 10KB smaller.
  2. The surface I tried to rotate did not display.
  3. I removed the dependency, the files, but it still gave me the
    error… I had to restart VC. (It’s a beta version, so I wouldn’t be
    so surprised…)

Anyways, did I have to copy/include all the .C and .H files? Thanks!

Hello,
you can try the package from this url:
http://www.ferzkopp.net/Software/SDL_gfx-2.0/
there is a vc6- and vc7-projectfile inside and also a description how to
compile it correctly.

You can also download the DevPak from sourceforge, it includes a .dll,
but I dont know if it works with VC.

And normally you don’t need to include all files, when you only want to
use rotozoom all you have to do is
include SDL_rotozoom.h, as far as I know.

Hope that helps.

Hmm… Well, I’m using VC++ .NET 2003, but the makefile is only in the
VC6 zip file… :frowning:
If I attempt to compile it, I get this:=================================

makefile(12) : fatal error U1035: syntax error : expected ‘:’ or ‘=’
separator
Stop.

Is there a VC7 makefile? Thanks!

PS: I also have VC6 installed, even though I don’t use it… (lol) And
using its nmake gives me the same error! Is it a problem with the
makefile? Thanks!

I don’t use Visual Studio, but there is a VisualC7.zip with a project
file in the archive, maybe that works?
Sorry but I can’t tell you if there is an problem with the makefile, I
don’t know how those things work :frowning:
Someone else on this mailinglist can probably help you, or you can write
the author a mail.

Hello !

Can anyone help me? The question basically was how to compile
SDL_rotozoom correctly or where to get a precompiled lib/dll files…

Basically you include the .h File in your code
and link the SDL_rotozoom Object File created from SDL_rotozoom.c

4 days, no reply… :frowning:
