[gtk-vnc-devel] [patch] build fail on Solaris.

[Halton Huo <Halton Huo Sun COM>]

Hi there,

I'm trying to build gtk-vnc trunk code on Solaris, but met ld fail, see following error message:

/ws/onnv-tools-prc/SUNWspro/SS11/bin/cc -DHAVE_CONFIG_H -I. -I.. -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/X11/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/sfw/include -I/usr/sfw/include/freetype2 -I/usr/include/libpng12 -DSYSCONFDIR=\"/export/home/halton/work/dist/etc\" -g -c gvnc.c  -KPIC -DPIC -o .libs/libgtk_vnc_1_0_la-gvnc.o
"gvnc.c", line 29: cannot find include file: <endian.h>

When I add -I/usr/include/ast to (where endian.h is located) to CFLAGS , get another error like some symbol not found:

/ws/onnv-tools-prc/SUNWspro/SS11/bin/cc -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/X11/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/sfw/include -I/usr/sfw/include/freetype2 -I/usr/include/libpng12 -I../src/ -I/usr/include/ast -o .libs/gvncviewer gvncviewer-gvncviewer.o  ../src/.libs/libgtk-vnc-1.0.so -L/usr/X11/lib -lgnutls -lgtk-x11-2.0 -lgdk-x11-2.0 -lXi -lXext -lX11 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lmlib -lpangocairo-1.0 -lfontconfig -lXrandr -lXcomposite -lXdamage -lpango-1.0 -lcairo -lXfixes -lgobject-2.0 -lgmodule-2.0 -lglib-2.0 -R/export/home/halton/work/dist/lib -R/usr/X11/lib

_ast_malloc                         ../src/.libs/libgtk-vnc-1.0.so
_ast_sscanf                         ../src/.libs/libgtk-vnc-1.0.so
_ast_strdup                         ../src/.libs/libgtk-vnc-1.0.so
_ast_free                           ../src/.libs/libgtk-vnc-1.0.so
_ast_fprintf                        gvncviewer-gvncviewer.o
_Sfstderr                           gvncviewer-gvncviewer.o

Then add -last should be added to LDFLAGS to resolve the build problem.

Now I'm aware of gtk-vnc use some headers and libraries, which Solaris ships in different way.

So I made a patch to resolve this issue, hope does not make any bad effect on Linux.

Thanks,
Halton.
