<== Failed to process package 'cartographer_ros': 
  Command '['/home/a/carto/install_isolated/env.sh', 'cmake', '/home/a/carto/src/cartographer_ros/cartographer_ros', '-DCATKIN_DEVEL_PREFIX=/home/a/carto/devel_isolated/cartographer_ros', '-DCMAKE_INSTALL_PREFIX=/home/a/carto/install_isolated', '-G', 'Ninja']' returned non-zero exit status 1.

Reproduce this error by running:

解决方案：

sudo apt install libgmock-dev

问题2 ：

代码运行时

[FATAL] [1713248900.406892955]: F0416 14:28:20.000000  7921 lua_parameter_dictionary.cc:83] Check failed: status == 0 (2 vs. 0) [string "include "map_builder.lua"..."]:35: attempt to index field 'pure_localization_trimmer' (a nil value)

在lua中pure_localization_trimmer的设置可能找不到，需要对比一下出处是否有定义或则定义内容更改等。经对比发现TRAJECTORY_BUILDER中对该内容进行注释。所以找不到。

TRAJECTORY_BUILDER = {
  trajectory_builder_2d = TRAJECTORY_BUILDER_2D,
  trajectory_builder_3d = TRAJECTORY_BUILDER_3D,
  -- pure_localization_trimmer = {
  --   max_submaps_to_keep = 3,
  -- },
  collate_fixed_frame = true,
  collate_landmarks = false,
}
