Hello,
After reading Craig's excellent blog post at https://blog.2ndquadrant.com/compiling-postgresql-extensions-visual-studio-windows/ I decided to try and build a real extension - tds_fdw.
I've set it up in Visual Studio Community 2017, but am getting the following errors:
Error C2375 'tds_fdw_handler': redefinition; different linkage tds_fdw E:\Workspace\git\tds_fdw\src\tds_fdw.c 118
Error C2375 'tds_fdw_validator': redefinition; different linkage tds_fdw E:\Workspace\git\tds_fdw\src\tds_fdw.c 156
Full output:

========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
I'm not sure if it's related, but the FreeTDS version that I found for Windows is marked as 32bit and I am trying to build for 64bit.
I believe that extensions like tds_fdw and pgloader will help users on TDS databases to migrate to Postgres and will improve adoption of the project. I will be more than happy to publish my binaries of the extension if I ever get that far.
Can anyone help?
Thanks,
