找不到'jpeglib.h'文件

'jpeglib.h' file not found

本文关键字：文件 jpeglib 找不到      更新时间：2023-10-16

我正在尝试在c++中读取jpg图像。我下载了libjpg，因为它是建议在这个链接https://www.opengl.org/wiki/Image_Libraries并安装它。虽然当我包含库Xcode失败构建说'jpeglib.h'文件未找到

#include <jpeglib.h>

我可以在/usr/local/include/目录中看到头文件，所以我不明白为什么Xcode看不到它。

OS and Software details:

OSX 10.11 (El Capitan)

Xcode 7.0.1

好的，看起来你只需要:

  1. 将/usr/local/include添加到头搜索路径 (turn recursiveoff)。
  2. 从与库链接二进制文件中显式链接/usr/local/lib/libjpeg.a(参考)。这将链接到静态库，这意味着不需要在应用程序中分发JPEG动态库。
