I'm building on AIX 5.3 but I'm thinking this is on most (all?) platforms.
I'm doing an out of tree build and got an error with:
/usr/local/build/postgres-9.0.4/../../src/postgresql-9.0.4/src/backend/utils/cache/relcache.c:57:30: error: catalog/schemapg.h: No such file or directory
I think the symbolic link is wrong. It is currently set to:
ls -l src/include/catalog/schemapg.h
lrwxrwxrwx 1 root system 62 Jun 12 15:14 src/include/catalog/schemapg.h -> /usr/local/build/postgres-9.0.4/src/backend/catalog/schemapg.h
and it probably should be pointing to:
/usr/local/src/postgresql-9.0.4/src/backend/catalog/schemapg.h
