Hello,
I was looking into using Cygwin for commercial use, but I couldn't really
understand if that was ok or not.
From here <https://cygwin.com/licensing.html> and here
<https://www.redhat.com/en/blog/cygwin-library-now-available-under-gnu-lesser-general-public-license>,
it seems like the basic cygwin library is available under LGPL, so ok to be
redistributed commercially if linked dynamically.
When I looked for all the different dlls though, I couldn't really find all
the licenses. I looked at /usr/share/doc folder but could not find the
licenses for several packages
+cygblas-0.dll
+cyggfortran-4.dll
+cyggomp-1.dll
+cyglapack-0.dll
+cygncursesw-10.dll
+cygquadmath-0.dll
+cygreadline7.dll
Is there any way you could provide some guidance on the topic? Is it
something you could help with?
(Of course in exchange of compensation)
Thanks for your help.

in general there is no restriction on usage.
License are located on:
for lapack and Blas:
$ cygcheck -l liblapack-devel
/usr/share/doc/Cygwin/lapack.README
/usr/share/doc/lapack/LICENSE
/usr/share/doc/lapack/README.md
for gcc/fortran and gomp
$ cygcheck -l gcc-core | grep COPYING
/usr/share/doc/gcc/COPYING
/usr/share/doc/gcc/COPYING.LIB
for ncurses
$ cygcheck -l ncurses | grep COPYING
/usr/share/doc/ncurses/COPYING
there are same restrictions if you plan to incorporate
the tools in your own software tif you are redistributing it.
(copy of source must also be distributed)

Marco
