expected unqualified-id before string constant

Question

I\'m currently writing a C++ application which implements an Oscillator in conjuction with math.h. The code I have should work fine for the application (trying to compile an obj

Answer 1

Your code has multiple problems:

• You need to fully qualify names(void oscillators::print_table() instead of just void print_table()) in oscillators.cpp
• You probably need to #include "oscillators.h" into oscillators.cpp
• You need to properly declare variables in implementation
• Add missing semicolons.

But I guess that specific error is caused by missing semicolon after class definition in header file. Just add it like:

    std::vector<double> gtable_; // Will contain a wavetable with a guard point.
};
#endif

Answer 2

Another way to produce this error: define a macro to a string constant, and later, use the macro name as the name of a string constant. Example

#define FOO "bar"
static const char FOO[] = "bar"; // <-- Error "expected unqualified-id before string constant".

The obvious answer is to remove one of the definitions, or change the name of one.

Answer 3

This is a simple problem.

You just forgot the semi colon at the end of your header file.

The compiler errors you get for missing the semi colon at the end of a class definition are very hard to relate to the actual problem - just get in the habit of checking that when you get errors after you create a class.
