The following Python versions were detected: 1. Python 2.7 Note: Experimental /enablemeson command-line argument is not set. We won't attempt to build Mesa3D if you pick any of the folowing Python versions: 5. Python 3.6 Select Python version by entering its index from the table above:1 Using Python 2.7.15 from C:\Software\DEVELO~1\projects\mesa\Python\python.exe. Install/update python packages (y/n): Begin LLVM build. Only needs to run once for each ABI and version. Proceed (y/n): Begin mesa build. Proceed (y/n):y Do you want to build off-screen rendering drivers (y/n):y Do you want to build GLAPI and GLES support (y/n):y Build Mesa without LLVM (y/n). Only softpipe and osmesa will be available: Do you want to build swr drivers? (y=yes): Do you want to build graw library (y/n): Do you want to clean build (y/n): Build command: C:\Software\DEVELO~1\projects\mesa\Python\python.exe C:\Software\DEVELO~1\projects\mesa\Python\Scripts\scons.py build=release platform=windows machine=x86_64 osmesa gles=1 scons: Reading SConscript files ...
