error: need 'typename' before 'std::conditional<std::is_same<char, char>::value, fmt::BasicMemoryWriter<char>, fmt::BasicMemoryWriter<wchar_t> >::type' because 'std::conditional<std::is_same<char, char>::value, fmt::BasicMemoryWriter<char>, fmt::BasicMemoryWriter<wchar_t> >' is a dependent scope

On line 85 in file sinks/wincolor_sink.h:
back_color &= ~(FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE |
FOREGROUND_INTENSITY);
'back_color' is of type 'WORD' (unsigned short) whereas a bitwise
complement/NOT returns an int. This results in a conversion warning with
-Wconversion enabled.
85:20: warning: conversion to 'WORD {aka short unsigned int}' from 'int'
may alter its value [-Wconversion] back_color &= ~(FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
Possible solution:
We know that the result of ~(FOREGROUND_RED | FOREGROUND_GREEN |
FOREGROUND_BLUE | FOREGROUND_INTENSITY) is always within the limits of
an unsigned short so a simple cast should suffice (correct me if I'm
wrong):
back_color &= static_cast<unsigned short>(~(FOREGROUND_RED |
FOREGROUND_GREEN | FOREGROUND_BLUE | FOREGROUND_INTENSITY));
Paths pointing to the root of the library where replaced for ones relatives to each file.
For example, inside /include/spdlog/details/file_helper.h:
This will look for os.h in /include/spdlog/details/spdlog/details/ which doesn't exists.
