Title: Failed to load image message contains wrong file name
Post by: tsero32 on January 30, 2013, 03:48:43 pm: I am trying to load an image from file to use as a sprite, this worked in debug but not the release

cout<<"start";

// Load the sprite image from a file
sf::Image Image;
cout<<"a"<<endl;
if (!Image.LoadFromFile("playerblock.png")){
cout<<"b"<<endl;
return EXIT_FAILURE;
}

the error message reads

" Fail to load image "erblock.png * " .Reason : Unable to open file "

Here is an image for clarification.

Just to reiterate, this works in the debug but I am getting this error in the release version.

I have had a quick look through but I can't find a similar error. I would really appreciate some help on this one

Post by: Foaly on January 30, 2013, 03:51:56 pm: Why are you putting a new line character at the end of your file name? I'm not sure, but that might be it.
Also you should move to SFML 2.0 for reasons explained in the FAQ (https://github.com/SFML/SFML/wiki/FAQ#wiki-grl-version).

Post by: Foaly on January 30, 2013, 04:13:38 pm: Try to remove all the code irrelevant to the problem. If the problem persist post a minimal and complete example (http://en.sfml-dev.org/forums/index.php?topic=5559.msg36368#msg36368).
Can you open the image with a image viewer or a image editing program?

Post by: tsero32 on January 30, 2013, 04:31:57 pm: #include "StdAfx.h"

using namespace std;

int main(){

sf::Image Image;
if (!Image.LoadFromFile("playerblock.png")){
return EXIT_FAILURE;
}
}

is the minimum complete example, it complains with out StdAfx.h which only contains:
#include <SFML/Graphics.hpp>

The image opens fine in other programs and in the debug version, the problem is still persisting.

Post by: eXpl0it3r on January 30, 2013, 04:36:04 pm: You should always start with an empty project and not use StdAfx, it doesn't give you much advantages and none if you use it wrongly.
You also shouldn't use using namespace std; since it will only hide where the functions and classes come from.
And you might want to read this (https://github.com/SFML/SFML/wiki/FAQ#wiki-grl-version).

As for your problem, make sure that the image is located in the working directory, also for the release version.

Are you linking against the release version of the libs?

Post by: tsero32 on January 30, 2013, 04:50:40 pm: In the release (with the problem) version I use the release libs and the debug uses the debug libs. Not sure how to prove and show this though.

The Image in the directory, I have come across all the advice to swap versions and I plan to do so, this has persuaded me more so, but before I swap I would like to know what the problem is here is there a reason my program error message would contain the wrong file name than the string I put in the argument.

Post by: tsero32 on January 30, 2013, 05:01:02 pm: Windows 7 home premium SP1 64bit , Microsoft Visual C++ 2010 ( i know its an IDE but I have completly forgotten what the complier is called.) I downloaded the 1.6 some time ago, so I believe it is the 2008 version.

Post by: Laurent on January 30, 2013, 08:24:23 pm: You can't mix versions of Visual C++. You need to recompile SFML.

Post by: tsero32 on February 01, 2013, 04:33:25 pm: Hmm I may have done, it was a while ago but I can't remember. So new plan, I shall swap to 2.0 and see if the problem persists.
