How to enable debug output / log?

[manphiz]

It looks like fre:ac uses a specialized directory structure to load its components (encoder, decoder). When trying to package fre:ac, boca, and smooth using FHS, fre:ac seems to have trouble finding the components. I saw that in the code there was debug strings with which I hope can help me find which directories it is using for loading the components, but I cannot figure out how to enable it. Please advise on how to enable the debug logging. Thanks!

The debug log can be viewed in the Logs tab when compiled with -DDEBUG. However, the Logs tab is provided by an extension, so if extensions cannot be loaded, you won't have that.

Components are expected in <install_prefix>/lib/boca and <install_prefix>/lib/freac, as determined in BoCA::Utilities::GetBoCADirectory(). You are probably using <install_prefix>/lib/<host_triple>/boca, yes?

I can update the code to also search in <path_containing_libboca.so> if that would help. I think that should fix it and make it work on multiarch systems too.

Edit: That would actually be the same as what is already done on Haiku in BoCA::Utilities::GetBoCADirectory().

Thanks a lot for the suggestions! I have done some local tests with working solutions. I have made 2 PRs against BoCA:

enzo1982/BoCA#19
enzo1982/BoCA#20

Please help review.

Oh, another weird thing: after I fixed bocaDirectory, the "-DDEBUG" no longer gives me the Logs tab anymore. I tried enabling it in both BoCA and fre:ac, still not working. But it was working when bocaDirectory was incorrect.

I wonder what could be the reason?

Following up on this: still having trouble enabling the log tab. Which extension controls the availability of the logs? I can enable the Job tag though.

[enzo1982]

The logs tab is implemented in the Protocols extension.

I think it could be that the fre:ac extensions are not found and loaded. The current codebase expects the fre:ac extensions in the same prefix as the BoCA components, in a freac folder sitting besides the boca folder.

So if you have the BoCA components in /usr/lib/x86_64-linux-gnu/boca, fre:ac components need to be in /usr/lib/x86_64-linux-gnu/freac or they will not be found.

Could that be it?

In any case, I guess I should fix that. I can provide a fix within a couple of days.

Indeed that was the issue. Initially as freac can launch fine I thought it was falling back to the "../lib/freac/freac" search path which kind of worked but only partially. I have made another PR[1] similar to the one for BoCA. PTAL.
