Compiling ODBC 12.0 on mac

Hi friends,

My company uses Tableau, which bundles outdated psqlodbc drivers, and as
such is proving a problem now that we've migrated to PG12. For windows
users I was able to solve the problem with the msi installer eazy peazy.
Mac not so much.

I downloaded the PG12 main source and compiled, then ran the psqlodbc
./configure pointing to the main compiled source using --with-libpq, and a
`make` and `sudo make install` later, I can see psqlodbcw.so, etc. in
/usr/local/lib with fresh timestamps.

However, this new driver causes Tableau to spit out a gibberish error
(unicode <?> chars) on trying to connect, so something isn't right. I don't
know if it's indicative of the problem, but if I run `make distcheck` I get
an error that pqlib is not found.

What is the best way to validate if the odbc driver is functional at a low
level to see if my compiled driver is bad, or if Tableau is just being a
jerk.

Cheers and Thanks,
Dan
