I am having problems with the flycapture SDK (FlyCapture v2.6 Rel 2) on Visual Studio. This is used for BlackFly camera.

I am getting the following errors:

and to my understanding the problem lies in the directories (include and library).

I have downloaded the FlyCapture SDK v2.6 Release 2 for Windows 32-bit and 64-bit.

In my project I have added the following properties:

Configuration Properties -> Linker -> Additional Library Directories : C:\Program Files\Point Grey Research\FlyCapture2\lib64\FlyCapture2_v100.lib

Configuration Properties -> C/C++ -> Additional Include Directories : C:\Program Files\Point Grey Research\FlyCapture2\include

I have tried to do this with the 32-bit and 64-bit SDK and with different lib's. But I don't know where I have done something wrong. All help is appreciated!!!

我一直在努力寻找问题所在，现在我找到了。VS2012 默认不支持 FlyCapture2 SDK。我不得不做出一些改变。

  1. 首先，我添加了属性（如上所述），但使用的是 32 位 SDK。

  2. 然后我进入安装SDK的文件夹。这里我去了 src\vsprops\VS10 并复制了 FlyCapture2.props 文件。

  3. 然后我重命名了副本，例如“FlyCapture2Changed.props”

  4. 打开“FlyCapture2Changed.props”（记事本、文本编辑器等），找到以下行：

注意！< 和 AdditionalDependencies 之间不应该有空格（与 </ 相同），这里的编辑器有一些问题（文本丢失）。

< AdditionalDependencies>FlyCapture2_$(PlatformToolset).lib;%(AdditionalDependencies)</AdditionalDependencies>

并将其更改为：

< AdditionalDependencies>FlyCapture2_v100.lib;%(AdditionalDependencies)</AdditionalDependencies>

完成此操作后，我必须对项目进行一些更改。在您的项目下，您应该转到属性管理器并右键单击调试 | Win32 并选择“添加现有属性表”并选择我制作的“FlyCapture2Changed.props”。

完成后，它起作用了！
