I’ve setup cgywin64, with the packages described here: https://github.com/JuliaLang/julia/blob/master/doc/src/devdocs/build/windows.md
git clone --branch release-1.4 https://github.com/JuliaLang/julia.git
echo 'XC_HOST = x86_64-w64-mingw32' > Make.user
And build with
make -j 8
This has worked OK with Julia 1.7 branch, but not with the julia 1.4 branch. It gives the following err:
What do I need to change to make it work?
