[osg-users] How do I get osgviewer on Cygwin to compile with -lX11 -lXrandr
I tried building OSG on Cygwin 1.7 and I first tried to do it without X but it seems that osgviewer seems to insist on X11 and that WIN32 option has been removed (or is that what you get if you leave it at none). At any rate I finally accepted the defaults (except adding -DNOMINMAX and was bale to get osg to build but to get edit several link.txt files during the build. I ran Cmake and did the configure and generate and then each time it bombed using something involving osgviewer then I would go edit the appropriate link.txt file and add -lX11 -lXrandr to the executable line in that file and then execute the file. This would complete the link and then when I started my make again it would move past that build and continue. I did this for each link failure as follow: In the build directory for OSG (my build root is /usr/develop/obj/osg): /usr/develop/obj/osg/src/osgViewer I edited the file: vi ./CMakeFiles/osgViewer.dir/link.txt and added the -lX11 -lXrandr to the line in link.txt. I then executed the link.txt file as in : ./CMakeFiles/osgViewer.dir/link.txt and the file built - so that was all it needed for osgViewer but... I then would have to do this other parts of the build (osgArchive, osgConv and so on ) to get it to finish. My question(s) is/are where do I find the logic that dictates during the Cmake configure what libs to include and in what files will I find this when the generate finishes. I would like to tweak this so the cmake configure and generate for cygwin was smart enough add the X11 and Xrandr libs. I would also like to know (if any knows) what in general should be the setting to get osgviewer to build without X11 on Cygwin and just use the opengl and no X. thanks bk ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

It should be smart enough to do it by itself; however I guess that you
can manually configure it by setting X11_X11_LIB and X11_Xrandr_LIB
parameters of CMake. These take the path of the libraries, as in
/usr/lib/libXrandr.so. As a last resort, you can set the parameters
CMAKE_{EXE,MODULE,SHARED}_LINKER_FLAGS to include -lX11 -lXrandr.

It's been some time since I don't build OSG in Cygwin, but using the
Win32 API on Cygwin applications should be more and more difficult every
day. Coherently, the CMake port for Cygwin is deprecating the WIN32
definition, since it aims to be a POSIX platform. However, I have seen
that X for Cygwin has now experimental support for hardware
acceleration.

Strange thing is - the configure populates those - it apparently finds them
during configure but then either the generate or something when I do the build
doesn't because when i do the build the -lX11 and -lXrandr isn't included (at
least according to the link.txt files I look at.
thanks.
