Question

我目前正在尝试在CentOS 7上编译程序，并且发生以下错误。

它在ubuntu 18.04上很好用，但在CentOS 7上不起作用。

db/obj-db.o: In function `std::vector<std::string, std::allocator<std::string> >::_M_range_check(unsigned long) const':

centos 7 有一个旧的 gcc 版本，可能是 4.8.5。但是现在很多库需要更高的版本。您可以运行以下命令以使用更高的 gcc 版本

sudo yum update -y
sudo yum install centos-release-scl
sudo yum install devtoolset-8 # gcc 8 is part of this toolset
scl enable devtoolset-8 bash # make the gcc version be 8.3.1

devtoolset-7 stl_vector.h未定义对`std :: __ throw_out_of_range_fmt（char const *，...）'的引用
