Mac - linking error (dyld: Symbol not found: __cg_jpeg_resync_to_restart) in beta but not stable #34869

compressed · 2016-07-16T21:39:10Z

This came up in sgrif/pq-sys#1. It seems when trying to run/test anything using beta or later this crate fails to run (not build) with the below error.

Note: I don't have DYLD_LIBRARY_PATH set as an env var anywhere. It seems to be picking up the wrong libJPEG.dylib in beta (/usr/local/lib) instead of in the OSX library location (/System/Library/Frameworks/ImageIO.framework/Resources/...). In part, I believe this to be due do the fact that the pg-sql crate is adding native=/usr/local/lib via -L because that's where the postgresql libraries from homebrew end up being installed. Curiously though, this linking problem does not occur on stable, leading me to believe it is resolving to the proper libJPEG.dylib instead of the one in /usr/local/lib.

Running OSX 10.11.5.

Also, not sure if related or not, but I tried the workaround specified in #34754, codegen-units=1, but it did not eliminate the error.

Beta (or nightly):

I'm not sure of a smaller set to replicate. In order to get into this situation on a mac, you need to have done the following:

brew install postgres
brew install libjpeg. This will add /usr/local/lib/libjpeg.dylib which beta ends up linking to.

Where the dependency on ImageIO comes from? Is it the pgsql library itself?

My initial impression is UB caused by a miscofigured system rather than an actual regression (i.e. its a miracle it worked before). Given the compilation succeeded, the linker got the right library/framework/etc and linked the binary up properly. After that, its all in the loader’s hands.

@nagisa thanks for the insight! Yes, I believe postgres requires libjpeg.

Your comment led me to an interesting finding: when running the built binary directly on my shell, it doesn't generate the linking error... Only when invoked with cargo run does this occur. Maybe an issue with cargo then?

Got it - this is due to this cargo change rust-lang/cargo#2763, which explains why stable and beta have different behavior. Error starts with the 2016-06-07 nightly.

Edit: The reason this worked before is because DYLD_LIBRARY_PATH had native=/usr/local/lib added instead of /usr/local/lib, so /usr/local/lib/libjpeg.dylib could never have been found because /usr/local/lib wasn't added to DYLD_LIBRARY_PATH correctly. With the cargo bug fixed, now this issue has appeared :) We should be able to resolve this in pq-sys directly.

I ran into this today with a fresh install of rust nightly on a MacBook.
