Ubuntu18.04下编译ORB_SLAM3遇到的问题

参考博文：https://blog.csdn.net/weixin_42203839/article/details/107728106 ORB_SLAM3的编译及运行【完整教程】

1.E: Unable to correct problems, you have held broken packages 类似下图

推荐解决方案：换阿里云镜像源(具体换源方法 百度很多)

其它参考方案：

https://www.cnblogs.com/schips/p/12470790.html        更换源

https://www.cnblogs.com/aaron-agu/p/8862624.html   使用aptitude(貌似不太安全)

https://blog.csdn.net/cnmilan/article/details/38270831 先删除，后安装(太繁琐)

 

2.fatal error: boost/serialization/serialization.hpp: No such file or directory

解决方案：sudo apt install libboost-filesystem-dev

 

3.c++: internal compiler error: Killed (program cc1plus)

推荐解决方案：使用make –j2 或者 make -jn 或者 make(而不是make -j) (建议将n设为cpu逻辑数量)

查看linux 版本： cat /proc/version
cpu逻辑数量：   cat /proc/cpuinfo |grep "processor"|sort -u|wc -l

参考方案：https://blog.csdn.net/u011897411/article/details/89742008

本渣渣电脑 运行./build.sh  编译24小时未果 果断放弃 查看其内部命令为 make –j 故改之

 

4.dd: failed to open '/swapfile': Text file busy

解决方案：sudo swapoff –a(watch free –m 监控内存变化)

 

5.fatal error: openssl/md5.h: No such file or directory

解决方案：sudo apt install libssl-dev

 

6.Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support

已经安装好了相应的库 重新编译之后还是这个错误 略坑

解决方案：需卸载opencv重新安装
