Build Filament From Source

Posted on 2022-08-03 Edited on 2024-09-28 In Coding , HowTo

I tried to build Google Filament from source, mostly using GCC/G++, ONLY except its main library Filament’s filament which is built with Clang/Clang++. Of course, I used ALL 3rdparty libraries either from default Ubuntu repository, or manually installed the newest version, rather than using the 3rdparty libraries coming with Filament itself.

How to Run PostgreSQL Server and Database?

Posted on 2022-06-03 Edited on 2024-09-28 In Coding , HowTo

1. Online Tutorials

2. Issues

2.1 `psycopg2.OperationalError: could not connect to server: Connection refused`

Relevant resource:

Solution:

Just modify this file /etc/postgresql/12/main/pg_hba.conf:

local all postgres peer => local all postgres trust
local all all peer => local all all md5

2.2 `Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432?`

Relevant resource:

Solution:

find the folder containing the file postmaster.pid, and remove it:
- rm /var/lib/postgresql/12/main/postmaster.pid
edit file /etc/postgresql/12/main/postgresql.conf, in which, set:
- listen_addresses = '*'
- port = 5432
- unix_socket_directory = '/var/run/postgresql'

2.3 CREATE EXTENSION in PostgreSQL

Relevant resource:

Solutions:

Please make sure postgresql-contrib has been installed.

2.4 Deal With GinIndex

Relevant resource:

Solutions:

Please make sure btree_gin and pg_trgm EXTENSIONs have been CREATEed for the user username in PostgreSQL database. Namely, you need to \c database username before CREATE EXTENSION btree_gin and CREATE EXTENSION pg_trgm.

2.5 `django.db.utils.ProgrammingError: syntax error at or near "FUNCTION"`

Solutions:

Use PROCEDURE instead of FUNCTION.

2.6 `django.db.migrations.exceptions.InconsistentMigrationHistory: Migration site.0001_initial is applied before its dependency account.0003_initial on database 'default'.`

Relevant resource:

django.db.migrations.exceptions.InconsistentMigrationHistory

Solutions:

Please make sure \c database username is run from within psql.

2.7 `LOG: SSL is not supported by this build`

Relevant resource:

How to check if PostgreSQL installation supports SSL?

Solutions:

1 2	⋊> ~ sudo su - postgres postgres=# postgres -D /usr/local/pgsql/data

3. Process

Step 1. Install `postgresql` and `postgresql-contrib`

⋊> ~ apt list --installed | grep postgresql                                                                                                                                                                                                                                  22:46:41
