I need the remote-viewer in virt-viewer package to connect a spice+gl unix domain.
the virt-viewer with opengl support requires spice-gtk(with opengl enabled).
So I need to build spice-gtk with opengl option. Then I experienced the following issue:
~/projects/spice-gtk$ ./autogen.sh --prefix=/usr --libdir=/usr/lib64 --enable-opengl && make
......
./.libs/libspice-client-glib-2.0.so: undefined reference to `gluTessVertex'
./.libs/libspice-client-glib-2.0.so: undefined reference to `glXCreatePixmap' ./.libs/libspice-client-glib-2.0.so: undefined reference to `glEnd' ./.libs/libspice-client-glib-2.0.so: undefined reference to `glXMakeCurrent' ./.libs/libspice-client-glib-2.0.so: undefined reference to `XFree' ./.libs/libspice-client-glib-2.0.so: undefined reference to `glEnable' ./.libs/libspice-client-glib-2.0.so: undefined reference to `glLineWidth' ./.libs/libspice-client-glib-2.0.so: undefined reference to `glBitmap' ......
See, The linker flag variable $GL_LIBS which the value should be '-lGL -lGLU' are not passed into Makefile correctly.
The variable $GL_LIBS should be generated/passed into Makefile.in first by m4 macro, Then finally the value '-lGL -lGLU' can be
attached to it correctly.
Thanks,
Lin
