我正在尝试在CentOS6上安装opencv2.4.9，我需要在Java中使用它。在找到所有依赖包的整个麻烦之后，我终于设法得到了cmake的积极结果，说：＆＃34;配置完成，生成完成＆＃34;。但是，当我尝试继续使用make命令时，我收到以下消息：＆＃34; make： * 未指定目标且未找到makefile。停止＆＃34;
我使用的cmake命令是：
cmake -DBUILD_SHARED_LIBS=OFF -D BUILD_NEW_PYTHON_SUPPORT=NO ..
并且输出的开头是：
-- Detected version of GNU GCC: 44 (404)
-- Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR)
-- Could NOT find JPEG (missing: JPEG_LIBRARY JPEG_INCLUDE_DIR)
-- Could NOT find Jasper (missing: JASPER_LIBRARIES JASPER_INCLUDE_DIR)

-- found libdc1394-2, version 2.1.2
-- checking for module 'libv4l1'
-- package 'libv4l1' not found
并且它继续，因此，在最后，输出是：

我在buildcv-2.4.9文件夹中创建的构建文件夹中运行cmake。在cmake之后，我尝试运行make，但它给了我上面提到的错误。我不知道如何继续，因为我不知道我在哪里犯错误。一些提示将不胜感激。
答案 0 :(得分：0)
问题是makefile在父文件夹中，所以我只在该文件夹中运行make。
