expected a file name error

[naveenpinto]

i am getting this error in core.h. does anyone have a solution for this issue, it is on visual studio C++ 2015.

Severity Code Description Project File Line
Error (active) expected a file name GExport c:\Users\JNP014\Documents\Visual Studio 2015\Projects\staticlogger\staticlogger\spdlog\fmt\bundled\core.h 183

It points to this code

// libc++ supports string_view in pre-c++17.
#if (FMT_HAS_INCLUDE(<string_view>) && (__cplusplus > 201402L || defined(_LIBCPP_VERSION))) ||
(defined(_MSVC_LANG) && _MSVC_LANG > 201402L && _MSC_VER >= 1910)
#include <string_view>
#define FMT_USE_STD_STRING_VIEW
#elif (FMT_HAS_INCLUDE(<experimental / string_view>) && __cplusplus >= 201402L)
#include <experimental/string_view>
#define FMT_USE_EXPERIMENTAL_STRING_VIEW
#endif

has anyone encountered this????

any solution for this bug would be appreciated!!!!!

This is strange. MSVC 2015 doesn't have __has_include (https://godbolt.org/z/070ovR), so FMT_HAS_INCLUDE should just expand to 0. Could you try compiling

#if defined(__has_include)
# error __has_include
#else
# error no __has_include
#endif

and posting the output here?

Does the error occur at compile time, or just in the IDE? The Intellisense frontend is uses EDG which may have limited __has_include support partly enabled even in VS2015.

@vitaut below is the output of the code you have supplied

@vitaut below is the compilation error

[naveenpinto]

This error pops up when there are existing errors in the code, if we clear the existing errors this error "expected a file name" goes off.

hear i have purposely added cout which give an error and the "expected a file" name error pops up

[vitaut]

This is a bug in IntelliSense which you can safely ignore or report to Microsoft that will ignore it for you. I've implemented a tentative workaround in 38ee424, but haven't tested as I don't have a Windows machine at hand.

@vitaut thanks a lot for the inputs!!!!!
