Build errors #283

Closed intergalacticmonkey closed 5 months ago

intergalacticmonkey commented 7 months ago

Trying to build as per the instructions in BUILD.md but there are build errors.

The first error I encountered was due to a simple typo in an XML file, which is fixed here: https://github.com/hardcore-sushi/DroidFS/pull/282

Then I started getting this error:

Execution failed for task ':app:buildCMakeRelWithDebInfo[arm64-v8a]'.

Downgrading the ndk to 23.1.7779620 as suggested in BUILD.md (and updating ndkVersion in app/build.gradle to tell it to use the older version) turns that error into a warning, which allows the build to continue further, but after that I get a new error:

I got it building using NDK 25.2.9519653.

hardcore-sushi commented 7 months ago

Yes libmux needs to be updated.

The second error log your provided seems incomplete. Can you show it in full?

Great 👍

Sure, but I'm not sure it's relevant, because I was trying to use an old NDK version and the newer versions seem to work fine (aside from that one error).

Anyway, here: 1_ld_error.txt

Thank you very much.

This seems to be the cause of the failure:

That's pretty weird. I've never encountered this error before.

I should update the build instructions to recommend a newer NDK version.

I'm closing this as discussed issues should be solved with 7c72c4e8294a8c25dc799a940f8142c12a759c8f.
