[postgis-users] ST_AsMVT Centos 7 Missing libprotobuf-c

[Regina Obe]

Devrim,

There are MVT tests that become enabled on PostGIS when protobuf building is enabled.

So you should see in your regress results in the first battery of tests:

mvt .. ok
geobuf .. ok

if you don't have sfcgal enabled, then they would be the last tests you see in the first battery of tests.

Hi,

I will work on this next week -- can you please let me know how I can test that this feature works, so that I release the package safely?

Regards, Devrim
