demo开发之问题04编译ubuntu环境下编译opencv
一、安装过程中出现的问题
1. looking for ccache --not found
sudo apt-get install ccache
2. Performance test HAVE)C_WSUGGEST_OVERRIDE - Failed
What parameter did you pass to cmake to allow for "Non-free algorithms: YES"? I have tried -D OPENCV_ENABLE_NON_FREE=ON and other combinations of that nature, but have yet to get the YES I want.
3. could not find jasper
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev
4. no package 'gtk+-3.0 found'
sudo apt-get install build-essential libgtk-3-dev
5. could not found OpenBLAS include. Turning OpenBLAS_FOUND off
https://github.com/opencv/opencv/issues/12957
https://stackoverflow.com/questions/36483054/install-openblas-via-apt-get-sudo-apt-get-install-openblas-dev
1）安装package
udo apt install libopenblas-dev, libopenblas-base
但是在安装过程中可能出现无法定位包的问题，即为unable to locate libopenblas-dev, libopenblas-base，这是可执行以下操作，
apt-cache search openblas
libblas-test - Basic Linear Algebra Subroutines 3, testing programs
libopenblas-base - Optimized BLAS (linear algebra) library based on GotoBLAS2
libopenblas-dev - Optimized BLAS (linear algebra) library based on GotoBLAS2然后再次安装；最后，执行以下操作。
sudo apt install liblapacke-dev
sudo ln -s /usr/include/lapacke.h /usr/include/x86_64-linux-gnu # corrected path for the library 2）修改配置文件
Appending these respective additional Paths in OpenCVFindOpenBLAS.cmake :
opencv/cmake/OpenCVFindOpenBLAS.cmake
Line 46 in eb981cc
SET(Open_BLAS_INCLUDE_SEARCH_PATH
and
opencv/cmake/OpenCVFindOpenBLAS.cmake
Line 58 in eb981cc
SET(Open_BLAS_LIB_SEARCH_PATHS
6. CBLAS/LAPACK header are not found in /usr/include/x86_64-linux-gun
7.Could NOT find HDF5
sudo apt-get install libhdf5-dev
8. module opencv-ovis disabled because OGRE3D was not found
sudo apt-get install libogre-1.9-dev # 1.9不能省略9.data downloda:face_landmark_model.dat==>timeout
将opencv/build/CMakeDownloadLog.txt中face_landmark_model选项的数据下载地址修改为https://github.com/opencv/opencv_3rdparty/blob/contrib_face_alignment_20170818/face_landmark_model.dat
10.VTK is not found，please set -DVTK_DIR in CMake to VTK build directory,or to VTK install
1) 从VTK官网下载最新的稳定版本
2）使用cmake重新编译，然后进入build文件执行sudo make install
11. Checking for modules 'tesseract;lept' No package 'tesseract' found Tesseract: NO
https://www.linux.com/blog/using-tesseract-ubuntu
1） 安装依赖包
$ sudo apt-get install libpng-dev libjpeg-dev libtiff-dev zlib1g-dev
$ sudo apt-get install gcc g++
$ sudo apt-get install autoconf automake libtool checkinstall
2）下载tessearct
$ cd ~ $ git clone https://github.com/tesseract-ocr/tesseract.git $ cd tesseract
3）使用cmake重新编译，保证没有错误
4）编译成功后，进入build问加减，执行以下命令：sudo make install
12.Found installed version of gflags: /usr/lib/x86_64-linux-gnu/cmake/gflags
Detected gflags version: 2.2.1
Failed to find glog - Could not find glog include directory, set GLOG_INCLUDE_DIR to directory containing glog/logging.h
Module opencv_sfm disabled because the following dependencies are not found: Glog/Gflags
sudo apt-get install -y libgflags-dev libgoogle-glog-dev liblmdb-dev13. Module opencv_ovis disabled because OGRE3D was not found
这里需要安装ogre3d，但是在安装它之前，需要先安装ois
1）从git上下载
https://github.com/ogre3d/OIS.git
2）cmake一下，然后进入build 完成sudo make install
3）git上下载
https://github.com/OGRECave/ogre.git
4）cmake一下
进入build，输入以下命令 sudo make install
14. Ceres Solver for reconstruction API is required.
1）检查依赖包是否安装
# google-glog + gflags sudo apt-get install libgoogle-glog-dev # BLAS & LAPACK sudo apt-get install libatlas-base-dev # Eigen3 sudo apt-get install libeigen3-dev # SuiteSparse and CXSparse (optional) # - If you want to build Ceres as a *static* library (the default) # you can use the SuiteSparse package in the main Ubuntu package # repository: sudo apt-get install libsuitesparse-dev # - However, if you want to build Ceres as a *shared* library, you must # add the following PPA: sudo add-apt-repository ppa:bzindovic/suitesparse-bugfix-1319687 sudo apt-get update sudo apt-get install libsuitesparse-dev
2）从github上下载ceres-solver
git clone https://github.com/ceres-solver/ceres-solver.git
3）重新编译，记得在build文件中运行sudo make install
15. Tesseract_include_dir not found in moudle/text
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
Tesseract_INCLUDE_DIR
used as include directory in directory /home/rodrigo/opencv_contrib-3.2.0/modules/text1) 把 Tesseract_build文件清空，重新编译。
2）把opencv的build文件清空，重新编译
二、总结
1）大部分问题是依赖包没有安装，所以在google的时候注意控制关键字，install XXX.
2) 不要着急，逐个攻破。
