Hello,

my program uses the plugin/ftp and cannot compile it.

The compiler does not recognise GLOBALREF that appear in /plugin/ftp/lib/ftplib.h


#if !defined(__FTPLIB_H)
#define __FTPLIB_H

#if defined(__unix__) || defined(VMS)
#define GLOBALDEF
#define GLOBALREF extern
#elif defined(_WIN32)
#define GLOBALDEF
#define GLOBALREF extern
/*
#if defined BUILDING_LIBRARY
#define GLOBALDEF __declspec(dllexport)
#define GLOBALREF __declspec(dllexport)
#else
#define GLOBALREF __declspec(dllimport)
#endif
*/
#endif

Does anybody knows how to fix this include file?
Thanks,
Luigi

Solved!

in plugin/ftp/lib/ftplib.f

line 27:

#if defined(__unix__) || defined(VMS) || defined(PLATFORM_MACOS)

instead of

#if defined(__unix__) || defined(VMS)

the same substitution in in plugin/ftp/lib/ftplib.cpp line 90

It seems (__unix__) does not cover macOS. Perhaps a more inclusive constant would be better.

Hello and thanks for investigation,

I found very interesting wiki page that shows what macros are available on each *nix operating system - http://nadeausoftware.com/articles/2012/01/c_c_tip_how_use_c ompiler_predefined_macros_detect_operating_system. As expected __unix__ is not defined on macOS. By default there is __APPLE__ or __MACH__ defined. I think for that special case (library code) we should use __APPLE__ macro instead of using pre-defined upp macros.

I created ticket for that - https://www.ultimatepp.org/redmine/issues/1945. I hope Mirek will accept the fix with additional ifdef. The library is no longer maintenance by their authors, so we need to patch it by our-self.

Sincerely,
Klugier
