Re: Issues compiling MADlib 1.12 for Postgres 10
+ dev@madlib.apache
From the developer perspective on why it's not working: 'format_procedure'
is a postgres function which is declared in regproc.h. Looking at the 10_3
branch it's still present in that file, so the declaration should be
available to the compiler.
Maybe search in the INCLUDEDIR-SERVER directory (available by running
pg_config) if 'format_procedure' is declared in regproc.h? It's possible
it's an include issue that's just showing up with that function.

Re: Issues compiling MADlib 1.12 for Postgres 10
Posted by Mauricio Scheffer <ma...@gmail.com>.
Thanks Orhan, Rahul. I was able to get past that error by
including <utils/regproc.h> in src/ports/postgres/dbconnector/UDF_impl.hpp
and src/ports/postgres/dbconnector/Backend.hpp
I got a couple other similar errors which I was able to easily patch and
finished compiling but then at runtime I got
could not load library "$libdir/libmadlib.so": ERROR: could not load
library "/usr/lib/postgresql/10/lib/libmadlib.so":
/usr/lib/postgresql/10/lib/libmadlib.so: undefined symbol:
_Z16format_procedurej
so I guess I'll just have to upgrade both Postgres and MADlib at the same
time.
Regards,
Mauricio
