It runs in about half a second on my Linux box (never actually measured it, but it’s fast).
About one minute with the build folder, instantaneous without on my Windows environment (msys2). So this is why I suggested to rm build first.
Something like that …
lensfun-update-data
cd ~/darktable/
rm -rf ~/darktable/build
git clean -dxf
git reset --hard
git fetch -p
git merge
git submodule update --init --recursive
mkdir build
cd build
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/darktable -DCUSTOM_CFLAGS=ON -DCMAKE_CXX_FLAGS="-O3" -DCMAKE_C_FLAGS="-O3" -DBINARY_PACKAGE_BUILD=OFF ../.

Sorry, I never realised it’d be so slow on Windows.
By this do you mean the git clean -dxf ; git reset --hard command

Yes, the “git clean” takes a long time on windows (depending on your machine, of course) if you do it before removing the ~/darktable/build folder.
I suggest adding an update via pacman before the cmake too.
NTFS with a bunch of small files really sucks. Its so slow
Thanks @dtrtuser for the explanation on git clean -dxf run times. Takes about 6 seconds on my win 10 computer. Maybe my NVME m.2 is helping here. Still, not even close to what @kofa gets on Linux.
Are you talking about this update, Pacman -Syuu?
pacman -Suy

kofa@eagle:~/darktable$ time git clean -d -f -x
Removing build/

This is with a SATA SSD, not with NVME m.2, after booting the computer, so nothing is cached.
And this is after just having finished building darktable:
kofa@eagle:~/darktable$ time git clean -d -f -x
Removing build/
real 0m0.251s
user 0m0.005s
sys 0m0.240s
kofa@eagle:~/darktable$
Basically no difference.
This is what I get on windows now (way better than this morning ,but still slower than you):
$ time git clean -d -f -x
Removing build/
real 0m4.460s
user 0m0.203s
sys 0m1.734s
And without /build
$ time git clean -d -f -x
real 0m0.033s
user 0m0.030s
sys 0m0.000s

And how much does deleting build manually (e.g. with rm or whatever you use) take?
Windows 10 22H2, i7-8700, 16GB memory, RTX 2060
$ time git clean -d -f -x
Removing build/
real 0m6.178s
user 0m0.125s
sys 0m0.952s
and without build
$ time git clean -d -f -x
real 0m0.079s
user 0m0.015s

@kofa I hope I got this right

On my system, right after a new build:
$ time rm -rf build/

I recently got this error message when compiling darktable. Any idea as to how to correct it?
