All,

While trying to install "pyarrow" and not able to find a distribution package so far I was trying to compile the Apache Arrow sources from https://arrow.apache.org/ under CYGWIN_NT-10.0 HW-016990 3.1.5(0.340/5/3).

I tried:
$ mkdir release; cd release/
$ cmake .. -DARROW_JEMALLOC=OFF
$ make

It fails with:

--- snip -----------------

Now since I think this is a rather popular package I was wondering if anyone has gone this journey already before me. (I noticed that Cygwin is not officially supported by Apache Arrow so far.)

Was anybody able to successfully compile that package? Any hints, help or advise?
Thank you so much,
-- Bernd
