I would look at the commands used to build the libraries. According the wasm-ld they don't have indexes. How is dist/lib/libavcodec.a being built? Can you post the command?

I had a similar error with a library that used the 'strip' command in it's build process to remove debugging symbols from the .a artifact. On Linux this seemed to get confused with the new backend and damaged the files; replacing strip with a no-op worked around it. Might be something to check for.

Interesting. Presumably this is because the native strip doesn't know anything about wasm object format. I'm surprised it clobbered the existing index though. Another solution there is to replace strip will llvm-strip which does know about those symbols.

I'm curious what version version this was on, and which backend - if this is a regression in the new backend that would be worrying.
kripken

I would imagine the same thing would happen with fastcomp, since strip also won't understand bitcode files, but perhaps fastcomp linking doesn't require a index in the way that wasm-ld does? If thats the case then we have become stricter yes. I'll will check. If if that is the case I'm not sure that really counts a regression but we should document it for sure.

Here's a gist with a small library build that triggers the different behavior between fastcomp (where it builds) and upstream (where it gives you the 'no index' error):
https://gist.github.com/brion/ef605cb6b71a81c763c59ed15efd9a78
I definitely recommend checking the ffmpeg build process for it running strip or other such modifications on the binaries, especially if it's being compiled in release mode that's a common thing to do. It may be easy to override the executable, or you may have to hack up the build or play tricks with the PATH. ;)

very sorry, i'm later :(

I got the wasm-ld: error: dist/lib/libavformat.a: archive has no index; run ranlib to add one

Can you remove the libavformat.a library and the rebuilt it in order to see exactly how it is being build?
e.g.
rm path/to/libavcodec.a
make path/to/libavcodec.a
@sbc100
Looks like this may be a common problem given the simple reproducer @brion provided. Perhaps the error wasm-ld: error: ./liba.a: archive has no index; run ranlib to add one could say a little more, like (avoid using the system "strip" command as it may remove the wasm index)?
Alternatively, could wasm-ld create the index on demand perhaps?
kripken
on 28 Oct 2019
I don't think it makes sense to build such magic into wasm-ld, but we can build more magic into emscripten if we like.
How about this:
for each_input_library:
if not has_index:
if STRICT:
error_with_useful_message()
else:
try_to_generate_index()
?

@sbc100 that sounds good!

ranlib -D libavcodec/libavcodec.a
So it looks like ffmpeg calls ranlib directly. If you want this to work you also need to specify --ranlib=emranlib on the configure command line.
You will also need to install 1.39.1 in order to get the fix for ranlib itself: #9714

Yes, after specifying this paramter [--ranlib="emranlib"], build successfully.
Thx :) I will close this issue later.
