[系统运维]服务器安装 colmap

Installation — COLMAP 3.7 documentation

按照里面的源码安装尽量安完 apt-get

准备 eigen

eigen>3.3 ，不然会报错

从这里下载 eigen 3.3.4

Eigen

Releases · libeigen / eigen · GitLab

放在 home 然后 cmake， make即可

准备ceres，

googlesource的打不开，用了github上面的

然后cmake? make 即可，它可以自己找到 eigen344

注意

cmake .. -DBUILD_TESTING=OFF -DBUILD_EXAMPLES=OFF

准备colmap

cmake时候需要额外设置，ceres在哪，安装在哪

有问题：多了一个空格编译的东西完全不一样

cmake .. -DCMAKE_PREFIX_PATH= /home/shilinzhe/ceres-solver/ -DCMAKE_INSTALL_PREFIX ../install/

?去掉空格

cmake .. -DCMAKE_PREFIX_PATH=/home/shilinzhe/ceres-solver/ -DCMAKE_INSTALL_PREFIX ../install/

出现错误：

Make Error at CMakeLists.txt:92 (find_package):
  By not providing "FindCeres.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Ceres", but
  CMake did not find one.

  Could not find a package configuration file provided by "Ceres" with any of
  the following names:

    CeresConfig.cmake
    ceres-config.cmake

  Add the installation prefix of "Ceres" to CMAKE_PREFIX_PATH or set
  "Ceres_DIR" to a directory containing one of the above files.  If "Ceres"
  provides a separate development package or SDK, be sure it has been
  installed.

然后

make DESTDIR= install -j4

安装后没找到/src/exe/colmap 可执行文件

重新cmake时候发现问题：

Use of gflags disabled - no tests or tools will be built!

CMake Warning at CMakeLists.txt:392 (find_package):
  By not providing "Findgflags.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "gflags", but
  CMake did not find one.

  Could not find a package configuration file provided by "gflags" (requested
  version 2.2.0) with any of the following names:

    gflagsConfig.cmake
    gflags-config.cmake

  Add the installation prefix of "gflags" to CMAKE_PREFIX_PATH or set
  "gflags_DIR" to a directory containing one of the above files.  If "gflags"
  provides a separate development package or SDK, be sure it has been
  installed.


-- Did not find Google Flags (gflags), Building without gflags.
-- Use of gflags disabled - no tests or tools will be built!
-- No preference for use of exported glog CMake configuration set, and no hints for include/library directories provided. Defaulting to preferring an installed/exported glog CMake configuration if available.
-- Failed to find installed glog CMake configuration, searching for glog build directories exported with CMake.
-- Failed to find an installed/exported CMake configuration for glog, will perform search for installed glog components.
Found Glog: /usr/include  
-- Found Google Log (glog). Assuming glog was NOT built with gflags support as gflags was not found.  If glog was built with gflags, please set the gflags search locations such that it can be found by Ceres.  Otherwise, Ceres may fail to link due to missing gflags symbols.

下载 编译 gflags

git clone https://github.com/gflags/gflags.git gflags_stable

在ceres的 cmakelists.txt的 增加

SET(gflags_DIR "/home/shilinzhe/gflags_stable/build")

然后

cmake .. -DBUILD_TESTING=OFF -DBUILD_EXAMPLES=OFF

可以得到

Found Google Flags (gflags) version 2.2.2: /home/shilinzhe/gflags_stable/build
然后make ceres 和colmap即可
