Can't build on ARM64 RockPro64 SoC - pg_ctl: command not found

[olleharstedt]

Running

make db-init

returns

make: /usr/lib/postgresql/10.12/bin/pg_ctl: Command not found
Makefile.db:101: recipe for target 'db-init' failed
make: *** [db-init] Error 127

Maybe pg_ctlcluster is meant instead? I can give more information about my system on request.

Running locate pg_ctl gives

/etc/alternatives/pg_ctl.1.gz
/etc/postgresql/10/main/pg_ctl.conf
/usr/bin/pg_ctlcluster

debian 10, postgresql 11.7: $ which pg_ctl || ls /usr/lib/postgresql/*/bin/pg_ctl | sort -nr -t / -k 5 | head -n 1 /usr/lib/postgresql/11/bin/pg_ctl Your make command is: /usr/lib/postgresql/10.12/bin/pg_ctl while pg_ctl is there: /usr/lib/postgresql/10/bin/pg_ctl hence the trouble.

Which version of ocsigen-start are you using? What is the result of the aforementioned which command?

[olleharstedt]

Sorry, the lack of websocket support makes Ocsigen not suitable for my use-case, so I will not continue debugging. Thanks for the feedback, though.

[MdeLv]

There are modules in ocsigen (Eliom, Js_of_ocaml, Lwt) to handle symmetric communications (in addition to automatic asymmetric communications - which saves bandwith, depending on tour use case).

I can see https://ocsigen.org/js_of_ocaml/3.1.0/api/WebSockets and other Lwt stuff. I let the ocsigen team, which is more qualified than me on that websocket subject, brings you specific information.

My experience is that there is a lot of stuff in the ocsigen framework that needs sometime to dig a little bit and ask support.

Can you elaborate a little bit about your use case?

[olleharstedt]

My use-case is a text based game engine, sort of. I'd like websockets for OCaml in both server and client side. Right now I'm using an old lib, lwt-websockets, and trying out js_of_ocaml separately from ocsigen.

[MdeLv]

As if the issue is closed it will probably not be seen.

There are of ocsigen modules related to socket/symmetric communications Maybe @Drup can recommend the right way how to do symmetric communications with ocsigen libraries?

• which modules to use (and which one are really deprecated, which one are old but can be used)
• how to combine asymmetric and symmetric communications (because there is no silver bullet)
• and maybe also nice ocsigen tricks

Thanks.

I wouldn't ping Drup unless necessary, haha. He knows who I am already, and is answering my questions on IRC and stackoverflow.
