Build Error

Trying to compile a checkout of 0.9.6 on Ubuntu 22.04.

Installed dependencies listed in readme.

From some searching around it sounds like one possibility is that it's getting killed due to running out of memory.

I tried "make" without -j4 but it still fails. To be clear, this is on a machine that only has 2 GB of RAM.

[jlopp]

I was able to compile the binary on a different Ubuntu machine with more RAM and then run it on this machine. Might be worth updating your documentation and/or making precompiled binaries available.

[hoytech]

Ahh yeah sorry about that, some of the files need a lot of memory to compile. You might be able to build it on the low-memory machine if you had some swap, although building it on a build server with lots of resources is a good way too.

I will look into distributing binaries somehow. What would be your preference? A deb package?

[jlopp]

Just the raw binary should suffice; I don't think there's a need for a deb package.

I'm getting the following error:

perl golpe/gen-fbs.pl perl golpe/gen-config.pl golpe/external/rasgueadb/rasgueadb-generate golpe.yaml build perl golpe/gen-main.cpp.pl error: /home/angelo/strfry/strfry/fbs/nostr-index.fbs:4: 16: error: expecting: ] instead got: : flatc failure building fbs/nostr-index.fbs at golpe/gen-fbs.pl line 22, <$fh> line 1. make: *** [golpe/rules.mk:44: build/golpe.h] Error 1 make: *** Waiting for unfinished jobs....

Any Idea? I'm using Ubuntu 20.04.5 LTS thanks

[hoytech]

I think the flatc that ships with 20.04 might not support some new syntax I'm using -- sorry! Easiest is probably to use 22.04.

I'm going to be getting rid of that flatbuffers file for the next major release, so I don't think it's worth figuring out a long-term fix.
