我正在尝试将第三方库移植到 Visual C++ 2013。该库有一些非常长的字符串，这些字符串似乎是 Base64 编码的数据。我将它们拆分为多个字符串文字，每个字符串文字都低于 Visual C++ 对字符串文字施加的 2,600 多个字符限制，但即便如此，仍有一些在连接后超过了 65,535 个字符的限制。
使用归结为:
boost::any value = +"abcd...";
有人可以建议一种使用超过 65k 的文字数据初始化 boost::any 的方法吗？
编辑:执行此操作的代码是从 XML 文件自动生成的。有数万个这样的值。对于 65,535 的限制，只有两个太长。
这使得任何使用动态内存分配(例如 std::string)的解决方案都没有吸引力，因为它会被代码生成实用程序应用于所有数以万计的解决方案，当只有两个需要它；动态内存分配会很昂贵。我更喜欢编译时解决方案。
最佳答案

Shutting up MSVC warning.
Dear Microsoft C/C++ Optimizing Compiler,
I hate you. After I chopped up my HTML template into tiny, tiny string pieces to appease you tiny fixed-size buffers,
I thought we could maybe be friends after all. But no. You had to go and give me more bullshit. You had to start your
ridiculous warning bullshit. The warning bullshit that there is no way to turn off without leaking crap to user code.
You're a joke.
Sincerely,

Now with no string pieces larger than 11k
Dear Microsoft C/C++ Optimizing Compiler,
It was a bit hilarious when you complained about that ~200kiB string
literal. The standard even has only a recommendation of 64kiB. This
16380 bytes per string piece bullshit, though? This is just ridiculous.
I hope this is the last hoop I have to jump through.
Sincerely,

HTML template string broken into pieces that are assembled on first use.
Dear Microsoft C/C++ Optimizing Compiler,
The 1990s called. They want their 64kiB fixed-size buffers back.
I didn't pay for 32GiB of RAM so that you could whine about a string
literal that is a few hundred kiB big.
Fuck You.
Sincerely,
rmf
我可以向您保证，这里已经报告了问题
您会注意到习惯性的 WONTFIX 响应。当然，这只是形式。显然在最新版本中发生了一些变化:
Is @R.MartinhoFernandes around? James told me that they've fixed the limitations on string literal lengths in VC2015 :) — jalf on Apr 25 10:33 PM
根据上下文，我们可以得出这可能是 James McNellis .
之前有过关于此限制细节的讨论 on march 5th .
