Increase string literal length limit

Question

I have a lot of string literals that are bigger than 65535 bytes. I'm not allowed to save these strings to seperate files, how can I workaround with the string limit?

• MSVC: 2048

• GCC: No Limit (up to 100,000 characters), but gives warning after 510 characters:

  String literal of length 100000 exceeds maximum length 509 that
  C90 compilers are required to support
  

Answer 1

These large strings seem more like resources than code, and I would use the resource section of a windows binary (FindResource/LoadResource) and the answer to the SO: embedding resources into linux executable to insert the same data into linux.

Answer 2

You can split the text string into multiple strings. Following code worked on Visual Studio 2017:

const char* p1 = "1234567890...";  // Very long (length > 65000)
const char* p2 = "abcdefghij...";  // Very long (length > 65000)
string s = p1;
s += p2;
cout << s.size() << endl;

You have to write the text string in multiple lines like:

const char* p = "This is a "
    "very long string...";

Actually the maximum limit in Visual C++ is 65535. Here is the compiler error message:

fatal error C1091: compiler limit: string exceeds 65535 bytes in length
