So, first of all it is (unfortunately) still not working...
What I did so far is this:
I removed my old GIT and installed the new one
I then removed Nemo within Julia and subsequently manually removed every
nemo stuff I could find in folder v0.5
I then started Julia (@Bill: This time I'm running Julia terminal directly
not via cygwin since Jeffrey asked to do it)
I ran: Pkg.update()
Restarting Julia
then: Pkg.clone("https://github.com/Nemocas/Nemo.jl")
Restarting Julia
Pkg.build("Nemo")
Now since it finally found GIT it downloaded the antic, flint2 and arb
stuff and builded Nemo.
Quitting Julia and replacing the files Bill linked above by the ones
already present in the folder Nemo/local/lib (actually libgmp-10.dll was
missing before)
Starting Julia and "using Nemo" with all the warnings....
restarting Julia and "using Nemo" again with no warnings...
but then again:
julia> using Nemo
Welcome to Nemo version 0.5.1
Nemo comes with absolutely no warranty whatsoever
