我在构建 snfit-2.4.2 时遇到类型错误
I'm getting a type error while building snfit-2.4.2
为了我的研究，我需要拟合一些超新星光曲线 (LC)。为此，有一些模板可用于拟合超新星光变曲线。一种这样的 LC 模板装配器是 snfit-2.4.2 。在从源代码构建 1it 时，我遇到了一些错误，如下所述：
salt2extinction.cc:132:10: error: no match for 'operator<<' (operand

构建snfit-2.4.2的源文件可以从以下网址下载：

我尝试在三台不同的机器上构建它：
我自己的机器：
AMD A8 7650 处理器
佐林 20.04 OS
我的工作站 #1 有：
英特尔至强八核
Ubuntu 18.04.2
我的工作站 #2 有：
英特尔至强八核
Ubuntu 20.04.2
在所有这些机器中，我都遇到了同样的问题。
我在 C++ 方面没有太多经验。
因此，我一开始就不太能理解这个问题。
简单的修复方法是将代码更改为：
stringstream message;
message << "ERROR Salt2ExtinctionLaw::Read unknown version " << version;
cerr << message.str() << endl;
为了我的研究，我需要拟合一些超新星光曲线 (LC)。为此，有一些模板可用于拟合超新星光变曲线。一种这样的 LC 模板装配器是 snfit-2.4.2 。在从源代码构建 1it 时，我遇到了一些错误，如下所述：

我尝试在三台不同的机器上构建它： 我自己的机器： AMD A8 7650 处理器 佐林 20.04 OS
我的工作站 #1 有：
英特尔至强八核 Ubuntu 18.04.2
我的工作站 #2 有：
英特尔至强八核 Ubuntu 20.04.2
在所有这些机器中，我都遇到了同样的问题。 我在 C++ 方面没有太多经验。 因此，我一开始就不太能理解这个问题。
简单的修复方法是将代码更改为：
stringstream message;
message << "ERROR Salt2ExtinctionLaw::Read unknown version " << version;
cerr << message.str() << endl;
