Hey after going through some Allegro 4.2 tuts, I decided to upgrade to Allegro 5 but I can't seem to get it working...here's what I did 1.Download the Binary version Then I start up Visual Studio and I try to do a tutorial 1// hello3.c
2// An introduction to bitmaps, input handling

29// But if it was not yet processed, leave the keynew flag

Please use <code></code> tags for code Other than that, I'm not entirely sure whats wrong, did you download the right binary package? The mingw version won't likely work with MSVC. -- |

you need to link to allegro-4.9.16.lib and allegro_image-4.9.16.lib ---------- |

K I've tried linking the .libs you told me to it justs says it doesn't know what it was...so I thought maybe I did it wrong so I tried DLing the Binary again and I'll see what happens... Then I tried using SVN and cmake but I only got as far as right before I start to build and I type in >cmake C:\allegro -G "Visual Studio 9 2008" -DSHARE=off But then it justs says it doesn't know what C:\allegro is and means... so far I'm just linking "kernel32.lib user32.lib gdi32.lib comdlg32.lib ole32.lib psapi.lib dinput8.lib d3d9.lib dxguid.lib winmm.lib opengl32.lib" but in allegro 4.2 I only need to link alld.lib... Any help would be apreciated, this is making me mad... |

when you run cmake what is the output it gives you? also if you make you project dynamicaly linked instead of static you wont need to link to kernel32.lib or any of those, just allegro-4.9.16.lib and the other allegro libraries your project requires ---------- |

Okay now for SVN its not working at all anymore for some reason "Access is denied" I'll try to binary version again... EDIT2: Okay okay I think I got most of it working now...all my unresolved errors are gone! Too bad that there are still errors...can someone help me with this, it was off a tutorial on Allegro Wiki, maybe I didn't link the right libs again... 1// hello1.c

With older versions of C you cannot define a variable in the middle of a block, e.g. line 65.

So its just the tutorials fault...okay! EDIT: It clearly shows that the tutorials are out of date my bad...I'll just sprite rip till a good tutorial comes out then...:-/ |

Keeley said: So its just the tutorials fault...okay! One could also argue that it's MSVC's fault for not supporting C99. One possible work-around is to compile your code as C++ code. The alternative is to move the declarations to the top of the scope where they are used (which is where they belong anyway |
