Hello Sir,
Thanks for the advise. I tried adding env = Environment(ENV =
{'PATH' : os.environ['PATH']}) , in the scons.py file. But, it is giving
the below error
env = Environment(ENV = {'PATH' : os.environ['PATH']})
NameError: name 'Environment' is not defined
SCons failed - exiting run.bat with code 5
Please guide me in which file I should add this.
Regards,
RS

This can be one of the most frustrating errors you can encounter with
SCons. Since SCons does not propagate environment variables,
including PATH, by default even if you are able to see ‘cl.exe’ before
you run scons it may not be able to find it in the scons scripts.
There is a logical reason to not pull in the environment variables it
helps avoid the ‘It works for me!’ build situations.
I would check:
-Are you using the latest version of SCons if you are using an older
compiler you can often get away with an older version of scons but for
the new compiler you need the latest version of SCons as well. You
should be running scons version 3.0.1
-Are you using the default install location for Visual Studio? SCons
searches for the default install locations.
The SCons faq page has some work around solutions:
https://scons.org/faq.html#Why_doesn.27t_SCons_find_my_compiler.2BAC8-linker.2BAC8-etc..3F_I_can_execute_it_just_fine_from_the_command_line.
None of the solutions are great they are a sledge hammer approach of
pulling in all of PATH or all of the environment variables and are
generally frowned upon as bad practice.

p.s. You can use python3 now, however you will run into issue IOT-3080
(https://jira.iotivity.org/browse/IOT-3080) see the top comment for a
work around if you switch.

Hello,
I am trying to compile Iotivity 1.3.1 on Windows 10 using Visual
Studio 17. I have installed all the dependencies like Python 2, Scons
and CMake. I am following the build instruction on
https://wiki.iotivity.org/windows. I am ending up with error saying
*/ 'cl' is not recognized as an internal or
external command, operable program or batch file./*
*//*I tried executing vcvars.bat and vcvars140.bat, but still getting
the same problem. Please advise on how to go about.
Regards,
RS
