How to build Opt on Windows 10

[mush881212]

Hello,

I am not familiar with building package. I checked out the Readme, but I still have no idea how to build Opt on windows 10, and I want to use it with VS2019.

Currently I download terra and unzip it to the "terra" folder (as the readme said). Then I run the buildOpt.bat with command line tool "x86_64 Cross Tools Command Prompt for VS 2019". The output is as bellow:

C:\DF\Optlang\Opt\API>buildOpt.bat C:\DF\Optlang\Opt\API>set OPT_DIR=C:\DF\Optlang\Opt\API\ C:\DF\Optlang\Opt\API>"C:\DF\Optlang\Opt\API\common\optMake.bat" "C:\DF\Optlang\Opt\API\....\terra" "C:\DF\Optlang\Opt\API\."

I got the error in createWrapper.t:130, is somebody know how to fix it, or if I miss some steps? Thank you for your help!

Have you solved it? I deleted the usemcjit = 1 and it could generate lib and dll file properly you can check this link https://github.com/terralang/terra/tree/master/release/include/terra and It says usemcjit is mandatory now.

@mush881212 But currently, I came across this problem on rtx2060 cuda11.1 vs2017, and still can't get it to work

.\util.t:874: cuModuleLoadData: cuda reported error 218: a PTX JIT compilation failed
stack traceback:

        [string "<string>"]:250: in function 'cudacompile'

(but it worked on my laptop with MX150 card, cuda9.2, vs2017)
