Oh I see, the confirmation email was being classified by GMail as a promotion and I missed it.

Microsoft forced an upgrade from Win 8 to Win 8.1 a few months ago, and I'm still recovering from that stab in the back. When I run OpenSCAD now, I see a dialog saying (in part) "Missing OpenGL capabilities - OpenCSG has been disabled"). Now, when I perform an F5 preview, some objects that are supposed to be differenced out are still visible, making it impossible to see what is going on. Using F6 takes forever, and I cannot use % or colors to see what is going on. I am finding development to be very slow. The hardware that I have has been abandoned by AMD, so there are no drivers to upgrade. Any tips? Thanks! Jon

You don't need to install MSYS2 for that, just download the package from either http://sourceforge.net/projects/msys2/files/REPOS/MINGW/i686/ (32 bit) or http://sourceforge.net/projects/msys2/files/REPOS/MINGW/x86_64/ (64 bit) and find some archive tool that can handle the XZ compression and Tar files (I think 7-zip should be able to extract those). ciao, Torsten.

Thanks, Torsten. When I run the MSYS2 installer, I get the message "this app cannot run on your PC" towards the end of the process. I get a series of error messages. Seems like this is not intended to run under Win 8.1 (which is WAY different than Win 7). Not sure what to do.

If yes, then just extracting the mesa version of opengl32.dll and putting that into the same folder as openscad.exe could work. ciao, Torsten.

But does not here. Thanks for trying. Jon On 1/19/2015 4:58 PM, Torsten Paul wrote: > On 01/19/2015 10:54 PM, jon wrote: >> Thanks, Torsten.

I've got a happy debug and release build MSYS2 environment working on both 8.1 and 7. If there is anything I can check in my install or help with please let me know.

urp. reading farther back in the thread, the problem described sounds a lot like what I got when I had to replace my hard drive and rebuild my laptop. Until I got the absolutely right Intel video drivers, I could not get the OpenGL to run. This is where I got them, but I don't know what graphics setup you have. https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=20046 Gulp. I don't have any DLLs in my 2014.03 OpenSCAD folder. Which dll is it again you're looking for, I can see if it's in my path. -- View this message in context: http://forum.openscad.org/Conway-polyhedron-operators-tp11037p11104.html Sent from the OpenSCAD mailing list archive at Nabble.com.
