GStreamer | gst-plugins-base | Ver: HEAD CVS
Summary: cross mingw32 gcc: getaddrinfo is not in ws2_32.dll
before Windows XP
Version: HEAD CVS
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: damien.lespiau at gmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
libgstsdp uses getaddrinfo and freeaddrinfo functions. These functions are not
in the winsocks DLL before windows XP. mingw32 knows this and its ws2tcpip.h
does not declare them unless the WINVER macro is set to Windows XP or above.
Thus, when trying to cross-compile with mingw32 from a linux box, the build
warning: implicit declaration of function `getaddrinfo'
warning: implicit declaration of function `freeaddrinfo'
and at link time:
undefined reference to `_getaddrinfo'
undefined reference to `_freeaddrinfo'
The right thing to do would be to provide a replacement for those functions to
support systems like windows 2000 (and maybe some Unixes) but for now I have a
patch to fix the build issue knowing that the DLL won't work with windows 2000
or earlier. This patch should not break anything and makes -base compile with
mingw32 so it still can be useful while waiting for someone that needs to have
gstreamer SDP working for windows 2000.
