wsl-1.0 ubuntu20+win ida7.5 counter a error of

[Cookgo]

I flow the Official website to build mcsema using native build approach.Everything seems OK.Since my ida is on Windows,so I use the command of
%IDA_ROOT%\ida64.exe -S"C:\Users\dkl\Desktop\source\mcsema\tools\mcsema_disass\ida7\get_cfg.py --output
C:\Users\dkl\Desktop\output.cfg --arch amd64 --os linux" C:\Users\dkl\Desktop\work\t2\a.out
to generate output.cfg ,that is OK
then
mcsema-lift-11.0 --arch amd64 --os linux --cfg ./output.cfg --output ./output.bc
that is OK,then
remill-clang-11 -o ./output ./output.bc -lpthread -lm -ldl -llzma -Wl,--section-start=.section_1ff00000=0x1ff00000

can someone has a solution? thanks

update:
During the buiding,I encounter two problem,one is

another is
cd anvill && git checkout -b release_bc3183b bc3183b
my buiding version is llvm-9 but I haven't modify git checkout -b release_bc3183b bc3183b

I am not sure weather these two place cause the fail,thanks for loook and help！
