I am trying to build Qt under Cygwin. For some mysterious reason Cygwin compiler does not expose popen with std=c++11 which is required for Qt BUT at the same time the MinGW compiler installed from Cygwin repository does expose popen with same standard flag. I did not yet find a convenient way of using MinGW compiler (which is prefixed) so I am stuggling to get popen exposed. What is the reason for this difference between MinGW and Cygwin? 2017-01-29 3:50 GMT+03:00, Пётр Б. : > tchar.h: http://pastebin.com/raw/109n342z > > So I only get popen if _POSIX_ is defined (which is not defined in any > header, I searched Cygwin folder with file manager). > > stdio.h: http://pastebin.com/raw/jrd2dmzP > > So I only get popen if some conditions which I did not hear about are > fullfilled.
