2 years ago I managed to follow the problem and the exception being mentioned as happening on line 86 looks to be raised due to a missing libplatform.h file which is a part of v8.
The part in the CAMotics build output that appears to ultimately be causing the exception is:
Checking for C++ header file libplatform/libplatform.h... no
Need C++ header libplatform/libplatform.h(cached) error: no resultI firstly concluded that v8 must've been built successfully due to a lack of errors in its SCons output as well as having the Checking for C++ header file v8.h... yes line in the CAMotics build output, now howerver with the focus on the missing libplatform.h i am no longer sure about that.
I am including the output of scons -C v8-3.14.5 mode=release arch=x64 library=static (v8 build) command below in hopes someone can help me shed some light on this problem.

I hope someone can help me shed some light on the a problem I encountered while trying to build on Windows 10 _64. While I was previously successful in building the package on Ubuntu 20.04, this time I was following the Windows_Build.md guide and managed to get the following error while running
scons -C CAMotics optimize=1:I would greatly appreciate any help or guidance that could point me towards a solution to this.
env.bat.scons -C v8-3.14.5 mode=release arch=x64 library=staticcommand completed witnout any problems and I have set the V8_HOME variable as described in the Windows_Build.md.env.batlooks like this:scons -C cbang disable_local="libevent re2" optimize=1output below:C! build output
