#include< FreeImage.h>未找到 [英] #include <FreeImage.h> not found

问题描述

我从源代码编译FreeImage并安装它。

当我运行 sudo make install 系统上的以下文件

  /usr/local/include/FreeImage.h 
 / usr / local / lib / libfreeimage-3.10.0.dylib 
 /usr/local/lib/libfreeimage.a 
  

但是在我的C ++程序中，当我这样做时，表示未找到错误文件：

  #include< FreeImage.h> 
  

我已尝试将其添加到我的系统路径文件中：

  sudo vi / etc / paths 
 
 #FreeImage 
 / usr / local / include 
 / usr / local / lib 
  

但是C ++仍然找不到我的 #include

解决方案

您不需要 $ c> / etc / paths 文件。该文件列出了shell搜索可执行文件的目录。

尝试：

  $ CFLAGS = -  I / usr / local / includeLDFLAGS = -  L / usr / local / libmake 
 $ sudo make install 
  pre> 
 
 
您可能需要将 / usr / local / lib 添加到您的 DYLD_LIBRARY_PATH 以确保您的可执行文件运行：
  $ export DYLD_LIBRARY_PATH = / usr / local / lib：$ DYLD_LIBRARY_PATH 
  
（假设 DYLD_LIBRARY_PATH 如果它是空的，你应该做 export DYLD_LIBRARY_PATH = / usr / local / lib 代替。）
 
 
 
 编辑：确定，根据您的意见，看起来这应该工作： 
  export CMAKE_INCLUDE_PATH = / usr / local / include 
 export CMAKE_LIBRARY_PATH = / usr / local / lib 
  
查看如果cmake找不到包，该怎么办
 
 
 
由于您使用的是Cmake的GUI版本，因此您应该这样做：
 
 
 
打开属性列表编辑器，点击添加子项。对于新项目，输入 CMAKE_INCLUDE_PATH ，对于Type，将其保留为String，对于Value，输入 / usr / local / include 。然后，再次单击添加项目，并为新项目输入 CMAKE_LIBRARY_PATH ，将类型保留为字符串，对于值，输入 / usr / local / lib 。然后将（文件 - >另存为）保存到文件。我建议在您的桌面文件夹中的文件名 a.plist 。然后打开终端（Appilcations  - > Utilities  - > Terminal）并输入：
  mv〜/ Desktop / a.plist〜 .MacOSX / environment.plist 
  
之后，退出Xcode和Cmake gui，然后重新启动。这应该工作。请参阅此的技术细节，以及此更多。
 
I have compiled FreeImage from source and installed it.

When I run sudo make install in installs the following files on my system
/usr/local/include/FreeImage.h
/usr/local/lib/libfreeimage-3.10.0.dylib
/usr/local/lib/libfreeimage.a
However in my C++ program it says error file not found when I do this:
#include <FreeImage.h>
I have tried adding this to my system path file:
sudo vi /etc/paths

#FreeImage
/usr/local/include
/usr/local/lib
But C++ still cannot find my #include inside Xcode or with gcc.
解决方案
You don't want those directories in your /etc/paths file.  That files lists the directories where the shell searches for executables.

Try:
$ CFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib" make
$ sudo make install
You might need to add /usr/local/lib to your DYLD_LIBRARY_PATH to make sure your executable runs:
$ export DYLD_LIBRARY_PATH=/usr/local/lib:$DYLD_LIBRARY_PATH
(Assuming your DYLD_LIBRARY_PATH variable doesn't have /usr/local/lib, and that it's not empty to begin with.  If it is empty, you should do export DYLD_LIBRARY_PATH=/usr/local/lib instead.)

Edit: OK, based on your comments, looks like this should work:
export CMAKE_INCLUDE_PATH=/usr/local/include
export CMAKE_LIBRARY_PATH=/usr/local/lib
See What to do if cmake doesn't find the package although it exists on the system? for more.

Since you're using a GUI version of Cmake, you should do this:

Open "property list editor", click "add child".  For "New item", enter CMAKE_INCLUDE_PATH, for Type, leave it as "String", for Value, enter /usr/local/include.  Then, click "add item" again, and enter CMAKE_LIBRARY_PATH for "New item", leave type as "String", and for  "Value", enter /usr/local/lib.  Then save (File -> Save as) to a file.  I suggest filename a.plist in your Desktop folder.  Then open a terminal (Appilcations -> Utilities -> Terminal) and type:
mv ~/Desktop/a.plist ~/.MacOSX/environment.plist
After that, quit Xcode and Cmake gui, and restart.  That should work.  See this for technical details, and this for more.
