打开Cv构建错误
打开Cv构建错误
提问于 2015-10-08 23:37:07
我正在尝试安装opencv版本3.0.0。我之前安装了2.4版本，没有错误，但3.0版本给我带来了很多麻烦。我一直在使用make命令时遇到错误。这是日志

我通过从源代码安装libgphoto2-2.5.7和gphoto2-2.5.6修复了类似的问题。
我找到了对我有帮助的this post，说明书归结为(但是使用make -j4来加速！)：
sudo apt-get install libltdl-dev libusb-dev libusb-1.0 libexif-dev libpopt-dev
# compile libgphoto2-2.5.7 from source
tar -xvzf libgphoto2-2.5.7.tar.gz
cd libgphoto2-2.5.7
./configure
make -j4 # use all 4 cores of the raspi!
sudo make install
# compile gphoto2-2.5.6 from source
tar -xvzf gphoto2-2.5.6.tar.gz
cd gphoto2-2.5.6
./configure
make -j4 # again use all 4 cores of the raspi!
sudo make install注意:没有找到这个gphoto2库之后的，所以我不得不添加这一行
include /usr/local/lib添加到文件/etc/ld.so.conf，然后运行ldconfig...

两天前，我也遇到了同样的问题，我采用了Dominic提出的解决方案。但不知何故，它仍然是错误的，我post it in my blog。今天，我要再试一次。我使用dpkg --get-selections | grep gphoto来查找我安装的与gphoto相关的内容：
libgphoto2-6:amd64 install
在我移除gphoto2-2.6并安装gphoto2-2.5.7之后，libgphoto2-6仍然在这里。因此，我删除了所有的gphoto，并再次遵循解决方案。在安装gphoto之后，我使用的是sudo ldconfig -v。现在我已经成功构建了openCV 3.1.0~

ctxMessageFunc/ctxStatusFunc/ctxMessageFunc的OpenCV声明具有与gphoto2中定义的参数列表不同的参数列表。
将代码修改为
friend void ctxErrorFunc(GPContext *, const char *, va_list args, void *);
friend void ctxStatusFunc(GPContext *, const char *, va_list args, void *);
friend void ctxMessageFunc(GPContext *, const char *, va_list args, void *);并应用下面相同的更改。
尽管如此，还有其他“函数缺失”的问题，我只是为了通过编译阶段将它们注释掉。如果你使用的是"videoio“模块，最好是获得一个兼容版本的gphoto2。
