This is probably related to the switch (I think last year some time?) from a local copy (in ham) of yaml-cpp to a package-manager installed version. My first guess is that the ham build directory, which is in the linker's path, has the old locally-compiled version of yaml-cpp, so it's mistakenly trying to link against that. So rm'ing the _build directory in packages/ham and recompiling should fix it (or probably just rm the yaml-cpp related objects/libs in there and re linking). Let me know if that doesn't work though.
No joy :( Is it possible my locally-compiled version is conflicting with the apt-installed one somehow?
Yeah, very possible. The functions that the linker is not finding could very well be only present in the newer version. Presumably you have two versions -- one in your conda env, and one in the system lib directories -- and you should be able to switch which is used by switching the order that the linker searches for them in. The easiest way I know to do that is with LD_LIBRARY_PATH. I don't know how to have the linker print which version it's finding from which path, but that is presumably also possible. So I'd do a find -name libyaml-cpp* <conda dir, system lib dir>
and try both of those at the start of LD_LIBRARY_PATH. It may also be possible to update both/one of the conda/system versions to a more recent version so they match.
It's referencing the right version of yaml-cpp, but I'm still getting the same error message:

just to be sure, the stuff this particular g++ call is attempting to link using /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libyaml-cpp.so
was definitely also compiled with the version at that location?
The main thing it seems not to find is convert_to_map(), which isn't something I'm actually calling directly, so it's got to be a version thing I think? Trying to see what version that was new in.
This sounds pretty similar, although I'm not sure it's super actionable.

Not sure I understand, but: that copy of libyaml-cpp.so
is the one installed by apt-get
and is the only one I can find on my computer. I also deleted the directory packages/ham/_build
and then re-ran bin/build.sh
, with the same results.
Oh sheesh I figured it out: the libyaml-cpp-dev
distro available for xenial is 0.5.2. I compiled and installed 0.6.2 locally and now we're back in business. Maybe you can include an explicit version check?
huh, that's super weird, sorry about that. On my desktop (also xenial), as far as i can tell 0.5.2 is working fine. Here's the partial output of that (amazing) g++ option:

-lyaml-cpp (/usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libyaml-cpp.so)
and if I ls the dir file it seems to be using:
lrwxrwxrwx 1 root root 18 Dec 1 2015 /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libyaml-cpp.so -> libyaml-cpp.so.0.5

The Dockerfile (which is what gets run by dockerhub on every push to master) is pulling from continuumio/anaconda which is using debian:latest, which seems to also be using 0.5.2.
And even on our server, where I don't have sudo access so for some reason I'm using a horrible hack where I copied the one .so file to a special dir and add it by hand to the scons file in packages/ham/, it's also 0.5.
The existence of 0.6 was the reason I moved off the local compiled version of yaml-cpp, since 0.6 removes the boost dependency, but then I had to add boost anyway, if I'm remembering right, since 0.6 wasn't yet in APT.
But I'm at a loss why it's not linking correctly for you. As far as I can tell the offending fcn has been there for five years?
The user in #282 seems to also be on 0.5, so whatever the issue was seems like was at least not universal.

Hi! Are there any updates about this? I have the same problem.
I don't have any updates, no. Near as I could tell though it still stemmed from somehow having two versions installed on the system, or compiling and running on different systems (as here), or something similar. It could for sure be a problem on my end, or at least something that I could add a check for, but at least as last I looked I couldn't figure out anything I could do. Let me know if there's anything I can do to help though.
