GCC 8.3.1中无法用TSDuck编译

Question

• TSDuck版本3.27.2438
• GCC版本8.3.1
• Centos 7.9

我正在尝试编译一些针对TSDuck的代码(RPM安装版本3.27-2438)。我在UString.h上得到一个编译错误。GCC似乎对在擦除功能中使用const_iterator表示不满。据我所知，这是自C++11以来允许的，应该在GCC 8.3.1中实施。还有其他人遇到过这个问题吗？这似乎是一个编译器错误，但我也在GCC 9.3.1中尝试过，并得到了同样的错误。

错误：

/usr/include/tsduck/tsUString.h:2088:84: error: no matching function for call to ‘ts::UString::erase(std::basic_string<char16_t>::const_iterator&)’
         iterator erase(const_iterator position) { return SuperClass::erase(position); }

检查您是否正在使用C++11 ABI。

macros.html

_GLIBCXX_USE_CXX11_ABI 默认情况下定义为值1。可配置通过--禁用-libstdcxx-双-abi和/或-默认-libstdcxx-abi。ABI-变化。当定义为非零值时，库头将使用GCC 5中引入的新的C++11符合ABI的ABI，而不是GCC 3.4中引入的旧的ABI。这改变了几个类模板的定义，包括std:string、std::list和一些locale方面。有关更多细节，请参见双ABI。
