我尝试通过cabal（cv）安装cabal install cv库。
但它给我带来了一个错误：
Configuring CV-0.3.7...
Building CV-0.3.7...
Preprocessing library CV-0.3.7...
c2hs: C header contains errors:
dist/build/CV/Video.chs.h:22: (column 39) [ERROR] >>> Unknown identifier!
Cannot find a definition for `CV_CAP_PROP_WHITE_BALANCE_BLUE_U' in the header file.
cabal: Error: some packages failed to install:
CV-0.3.7 failed during the building phase. The exception was:
ExitFailure 1
我已经读过它的问题是，我的安装opencv比haskell-library需要的更新。
我的opencv：
local/opencv 2.4.12.2-2
Open Source Computer Vision Library
那么我该如何解决这个错误呢？谢谢你的帮助！
