Dear Gerrit,

I have tried this workaround.

I'm trying to exhaust all the possibilities before submitting a bug.

Dear Marco,

I have tried the package from cygwin. It installed correctly and was
'kind of able to run' (imports went fine):
But somewhere in the first plot it threw an error. I do not have the
log here with me but it was something related to 'get_facecolor' in
matplotlib.

The exact same program was able to run flawless in my lubuntu so I
infer it is something to do with libgeos on cygwin.

Thank you both for your valuable input. I opened an issue on matplotlib basemap.

https://github.com/matplotlib/basemap/issues/314

I'll let you know when I have this problem solved.

Best regards,

Hi Felipe,
geos is already available in cygwin:

$ cygcheck -cd |grep geos
libgeos-devel                           3.5.0-1
libgeos_3_5                             3.5.0-1
libgeos_c1                              3.5.0-1

any reason to not use the available cygwin package ?

Hello Felipe,

> Can you suggest any work around?

I found this:

https://trac.osgeo.org/geos/ticket/595

So there seems to be some support? Also Autotools should work and find
if ISNAN is available or not?

I see here: https://trac.osgeo.org/geos
this information:

"Bug Reporting
You will need an OSGeo user account to submit bugs here. A "New
Ticket" button will appear once you have logged in."

Gerrit

I was trying a lot of google solutions but none of the worked.

Can you suggest any work around?

The libgeos github does not allow me to open an issue.

My ultimate goal is to use matplotlib Basemap.
