Hello.
Can somebody give advice what library defines g_object_unref function
call, please?
I use x86_64 Cygwin.
I would like to build rrdtool 1.6.0. Building it as Windows native app
is near impossible. Building it in Cygwin is much less pain and I hope
the "undefined reference to `g_object_unref'" is the last obstacle.
In Debian I found that g_object_unref is defined in libgobject-2.0.a,
but there is no library libgobject-2.0.a in Cygwin.

Answer is: Library libgobject-2.0.dll.a is a part of libglib2.0-devel.
I have installed libglib2.0-devel version 2.50.3-1 now, I added
-llibglib-2.0 -llibgobject-2.0 to LIBS and still have

"T" means symbol is defined in TEXT (code).
Is the "undefined reference to `g_object_unref'" result of "relocation
truncated to fit"?
