cmake --build . --target install --config Release --parallel 12 FAILS

[MatteoAzziniUnice]

Good morning and thanks for the help in advance. I'm trying to build your code but I have a problem with the command cmake --build . --target install --config Release

In fqct when I execute it it gives
In file included from /home/ealao/Desktop/ct_icp/src/SlamCore/io.cxx:6:0:
/home/ealao/Desktop/ct_icp/src/SlamCore/io.cxx: In function ‘std::vectorslam::PLYSchemaMapper::PLYProperty slam::{anonymous}::DefaultPropertiesFromSchema(const std::vectorslam::ItemSchema&, bool)’:
/home/ealao/Desktop/ct_icp/src/SlamCore/../../include/SlamCore/utils.h:30:32: error: ‘filesystem’ is not a member of ‘std’
#define SLAM_FILENAME std::filesystem::path(FILE).filename()

wich is weird since I#m using ubuntu 18, gcc 7.5 as required. Do you have any idea of how to solve it

编译器版本太旧，把gcc和g++更新到11
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-11
sudo apt-get install g++-11

//再次查看gcc版本
gcc -v
//发现还是7.5.0
//进入/usr/bin目录下删除旧版本gcc/g++文件
cd /usr/bin
sudo rm gcc g++
//建立软连接
sudo ln -s gcc-11 gcc
sudo ln -s g++-11 g++
//再次查看版本，发现变为11

//重新cmake ，通过
