我尝试安装OAT++。但失败了。
操作系统信息
[root@localhost build]# cat /etc/*-release
CentOS Linux release 7.6.1810 (Core)
如何解决以下错误？

我在ubuntu上成功安装了OAT++。
为什么在centos 7上安装OAT++失败？
您有失败的测试，而不是oatpp库本身
只需通过添加-DOATPP_BUILD_TESTS=OFFcmake标志来禁用测试并重建：
cmake -DOATPP_BUILD_TESTS=OFF ..
make install
修复测试：
在文件oatpp/test/oatpp/core/data/share/StringTemplateTest中更改所有出现类似代码：
auto result = t.format({oatpp::String("Hello")});
至
auto result = t.format(std::vector<oatpp::String>({"Hello"}));
如果您修复了测试，请发送PR
