ubuntu编译pcl时报错

报错如下
cc1plus: warning: -Wabi won't warn about anything [-Wabi]
cc1plus: note: -Wabi warns about differences from the most up-to-date 
ABI, which is also used by default
cc1plus: note: use e.g. -Wabi=11 to warn about changes from GCC 7

在网上找到了一封邮件

邮件内容如下

邮件的链接如下

Bernd Edlinger - PATCH Remove -Wabi from libstdc++ build options

邮件的意思是：它没有什么用处，可以将这个补丁删除。

因此在CMakeLists.txt文件删除这个东西即可
