Is this view of things accurate, or not? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=75737#75737 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I've updated removing the old mentions of the separate Producer/OpenThreads builds. I added mention the standard cmake based build. I don't have an Cygwin expertise though so don't know how close it will be to working correctly. If others have Cygwin expertise please edit the page or suggest amendments.

Re: [osg-users] [build] Particular Build Problems with OSG.
Hi Zachary, osg is cmake based for configuration. so instead of ./configure;make;make install you should do something like cmake . make make install cmake will generate the Makefiles On Wed, Mar 27, 2019 at 5:23 PM Robert Osfield wrote: > Hi Zachary, > > You will need to post us the errors you are seeing without this there > is no way for us to know what is wrong. > > Robert. > ___ > osg-users mailing list > osg-users@lists.openscenegraph.org > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > -- trajce nikolov nick ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Zachary, You will need to post us the errors you are seeing without this there is no way for us to know what is wrong. Robert. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] osgText::Text dissapears when reparent container window on qt
Hello,
This is a mixed OSG/Qt question. I asked first here due to previous
experiences with the community.
I'm following a minimal example of embedding OSG into a Qt5 application from
https://gist.github.com/vicrucann/874ec3c0a7ba4a814bd84756447bc798. When I
modify that example, and add a simple osgText::Text to the base Geode
everything works as expected. But If I ,additionally, encapsulate the OSG
Widget (a widget derived from QOpenGLWidget) on a QDockWidget and undock it,
the text dissapears.
Can someone point me out what could be the problem?
The code:

[osg-users] [build] Particular Build Problems with OSG.
I am attempting to build 64 bit OSG 3.6.3 for Windows using the GNU compiler, to keep my end result operable with 64 bit TDM. I am in the 64 bit Cygwin Environment. I have installed the dependencies mentioned as necessary at the top of the tutorial [url] http://www.openscenegraph.org/index.php/documentation/platform-specifics/windows/112-compiling-with-cygwin[/url] and have even managed to separately build OpenThreads successfully. I am up to the point where I am to make, make install upon OpenSceneGraph version 3.6.3 and am finding there is no make file to start by. I have taken the source code version of OSG from https://github.com/openscenegraph/OpenSceneGraph/tree/OpenSceneGraph-3.6.3 and have updated ~/.bashrc with links and references as needed. Do I have the right source code download of OSG, why won't configure make install detected the needed file for me, at least according to the later part of the tutorial? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=75732#75732 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
