Hi,
Thanks a lot for your valuable suggestion. I followed your instructions
and added the suggested lines. I had done minor modification to overcome
failure for multiple definition & warning due to one assertion failure.
I tried gtk-demo, but only background was drawn, no widget were visible.
After that, I compiled the gtk+ example, helloworld & executed. I observed
that background is drawn. But, no text is displayed for the button label. I
also tried to change button/label color by changing the gtkrc, that had also
no effect.
Now, can anyone suggest me a wawy to overcome this situation?
My packages are
glib-2.18.3 configured with --build=i386-linux --disable-gtk-doc
--disable-man --enable-debug
cairo-1.8.6 configured with --enable-directfb --disable-xlib --disable-win32
pixman-0.13.2
pango-1.22.3 configured with --without-x
Here is the change:
