Guys,
I'm getting this error when trying to compile libgeos:

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.

Best regards,

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,
