Yeah. There's also a problem with the dev package I think, because
-lpython3.8m can't find the library, and python3.8m doesn't seem to
exist as a command. I might just be being a doofus though so I'll double
check that I installed the right packages.
on python 3.8 they should be
-lpython3.8 and python3.8
You can use pkconfig to recover it
$ pkg-config --libs python-3.8
-lpython3.8
$ pkg-config --libs python-3.7
-lpython3.7m
Ah, thank you, that makes sense.
I have now built the packages for python 3.7 as well, from the same
source package. Your idea worked great :)
The new ones are available at the same place as before:

All seems to be working okay for me, but there are some notes/questions
I have:
- I get errors from python3.cygclass at the start of every build saying
it can't find "python3-config" - looks to be a missing
symlink/misconfigured cygclass script?
- On 32-bit Cygwin, stripping the debug symbols with objdump.exe from
the libraries takes an extremely long time - I reckon 3-4 times slower
than on 64-bit, at least. It's kind of prohibitively slow, does anyone
know why?
the 32bit has less memory space so it take a bit of file swapping when
the data are large
- On 32-bit Cygwin, I tend to get fork errors when running the wxPython
demo, but not on 64-bit (identical build options). Is this likely the
32-bit fork bug mentioned on Cygwin's home page, or a problem with my
installation/setup?
run demo in build dir ?
1) remove any excessive libraries from your cygwin 32 bit install.
Recently for a similar reason I removed all libboost except the
last one, a good of previous version like libicuXX and similar
that accumulated in the years.
2) rebase the built dll's without storing permanently the addresses.
Attached the script I am using for the scope
