Ubuntu 18.04 install woes

[kdm9]

Hello Iqbal Lab folks!

I'm trying to get gramtools running on our Ubuntu 18.04 cluster, but having significant issues:

• install with the precompiled binaries fails, due to GLIBC/GLIBCXX version issues (18.04 glibc too old I assume)
• install from source fails, as the OS compiler toolchain is too old
• install from source within a conda env with updated dependencies and GCC/G++ fails, as cmake picks up the updated gcc but not the updated ar/ranlib, and conan doesn't even pick up the updated gcc. This leads to all sorts of fun errors during compilation.
• making a conda package fails, due to some strange linking error deep in conan-land. It seems like the cmake config hard-codes that conan is the source of the dependencies, which interferes with some conda dependencies and causes conflicting symbol names (e.g. regarding some zlib symbols in libhts.a).
• Using docker/singularity isn't supported on our infrastructure, so i can't do that.

Is there any approach I'm missing? Is there any chance gramtools can move to HBB, or similar static compilation toolchains as discussed in the original "static binaries" issue?

Best, Kevin

Hi Kevin,

Thanks for raising this, and for logging everything you've tried. I will look into both compiling against older libc/something else than libc (musl) and making a bioconda package. Will update situation here!

Hi @kdm9 , could you try the latest release, v1.9.0?

I tried it in a Ubuntu 18.04 docker image and looks like it works :+1:

Also, do you have a pointer to the conda recipe you used when trying to build a package for gramtools? It would be quite helpful- I've had a first go but have not gotten as far as you i think.

Sorry, I forgot to say: this works perfectly on 18.04 now. Many thanks Brice!
