Compiling rtorrent-0.9.4-1 with cygport

Compiling rtorrent-0.9.4-1 with cygport

[Sorin Adrian Savu]

Hello!

I'm trying to compile rtorrent-0.9.4-1 with cygport to add support for XMLRPC.

I've added:
CYGCONF_ARGS="--with-xmlrpc-c"
in the cygport file.

When I try to compile, I get the following error:

/usr/src/rtorrent-0.9.4-1.src/rtorrent-0.9.4-1.x86_64/src/rtorrent-0.9.4/src/display/window_file_list.cc:
In function ‘std::wstring display::wstring_width(const string&, int)’:
/usr/src/rtorrent-0.9.4-1.src/rtorrent-0.9.4-1.x86_64/src/rtorrent-0.9.4/src/display/window_file_list.cc:80:38:
error: ‘wcswidth’ was not declared in this scope
   int swidth = wcswidth(result, width);
                                      ^
/usr/src/rtorrent-0.9.4-1.src/rtorrent-0.9.4-1.x86_64/src/rtorrent-0.9.4/src/display/window_file_list.cc:87:18:
error: ‘::wcwidth’ has not been declared
       int next = ::wcwidth(result[length]);
                  ^
After some investigation it seems to be related to _XOPEN_SOURCE
flag, but when I add that I get other errors.

I've tried compiling with the CYGCONF_ARGS commented out and the
behavior is the same.

Am I missing something ? How can I find out which compile flags were
used at the package build time ?

rtorrent package is currently 0.9.6-1.
Any reason for 0.9.4 ?

You are not missing anything.
CYGCONF_ARGS was empty for last binary build.

The cygwin headers changed from last time I built the rtorrent package.
I see the same error today.

Adding
  CXXFLAGS+=" -D_GNU_SOURCE"
to the cygport should solve the build problem.

about --with-xmlrpc-c, I think there is no cygwin package to
support such  configuration.

Regards
Marco

Yes, tracker doesn't accept 0.9.6-1

Tested today, and I can confirm it works. Would you mind pointing me
to some documentation/info about what changed in the headers ?

I've used the source package directly for lib xmlrpc-c

Thanks for your time!
