Boost filesystem should use POSIX API on cygwin

[frederic.bron@…]

Hi,

On cygwin, the following program

#include <iostream>

#include <boost/filesystem.hpp>

int main() {

auto p = boost::filesystem::path{"foo"}; p /= "bar"; std::cout << p.string() << '\n'; return 0;

}

outputs: foo\bar

but cygwin is a posix system and I expect: foo/bar

I read in the doc that "User-defined BOOST_POSIX_API and BOOST_WINDOWS_API macros are no longer supported."

I guess system/api_config.hpp should be:

-# if defined(_WIN32)

defined(CYGWIN) Windows default,

including MinGW and Cygwin +# if defined(_WIN32) Windows default, including MinGW # define BOOST_WINDOWS_API # else # define BOOST_POSIX_API # endif

I added the patch because it was all garbaged by the tracking system in the post.
