How do i fix this?

a location near that error message can be seen here https://github.com/lifting-bits/remill/blob/f096390b95d8528ff28e7e8d178b3577e34e0caa/lib/BC/Util.cpp#L513

if i had to guess it looks for the files here "D:/remill/remill/5.0/semantics//"

[jfmherokiller]

mcsema-lift-5.0.exe.zip
I patched the file to allow the relocation of the arch files to the current working directory under a "remillb" folder

@jfmherokiller I used your zip and replaced "D:\mcsema\bin\mcsema-lift-5.0.exe" with your zip'exe. But it also reported that error. Did I operate wrong?

Has anyone had a problem where the .bc file is created, and mcsema tries to create another file with the same name? This causes the mcsema bitcode generation to be stuck

Yes , its not a big problem
Just rename bc manualy on cmd
try cmd:
ren calc.bc.tmp.4940 calc.bc

This should work.
I will update this soon...

Hello eix128,

Did you get a chance to work on building the new version of Mcsema?

As you build the project on windows, please take notes on how you did it and share that notes with us as a tutorial if you can. There are many reports from people on the issue tracker on Mcsema stating that they could not compile the project on Windows by following the official instructions. It would be great if you can provide us the correct instructions for compiling this thing on windows.

You are our only hope at this point. :)
Thanks.
