将png ++设置为工作 [英] Setting png++ to work

问题描述

我试图编译一些使用png ++加载/编写.png图像的基本示例（这是一个用于libpng的c ++包装）。对我来说，使用png ++而不是一个替代品是非常重要的
作为先决条件png ++需要我已经成功构建的libpng。

I am trying to compile some basic example of loading/writing a .png image using png++ (which is a c++ wrapper for libpng. It is quite important for me to use png++ and not an alternative. As prerequisites png++ needs both libpng which I have successfully built.

我试图找出如何设置的示例位于以下链接
http://fedetft.wordpress.com/2010/10/ 05 / handling-png-images-in-cpp /
它附带一个cmakelist，我使用Cmake建立这两个例子。

the example that i am trying to figure out how to set is located at the following link. http://fedetft.wordpress.com/2010/10/05/handling-png-images-in-cpp/ it ships with a cmakelist and I am using Cmake to build the two examples.

但是当我构建这个我得到以下错误：无法检测到字节顺序来自config.hpp

however when I build this I get the following error : "Byte-order could not be detected." which comes from config.hpp

非常感谢

推荐答案

我想，libpng ++不正确定义一个WIN32平台。

I think, libpng++ incorrect defines a WIN32 platform.

在config.hpp文件中将 #elif defined（__ WIN32）替换为 #elif defined（WIN32）。

You can try to replace #elif defined(__WIN32) to #elif defined(WIN32) in config.hpp file.

PS我现在没有安装libpng ++，所以我可能错了。

P.S. I do not have libpng++ installed right now, so I may be wrong.

P.S.S。它只适用于Windows，ofc。

P.S.S. And it's only suitable for Windows, ofc.
