Tricky glib find on Ubuntu 18.04, Pkg.build("LCMCore") fails

[dehann]

Hi,

We had a little trouble with getting LCMCore to buildon 18.04. Turns out it was a simple fix:

sudo apt-get install libglib2.0-dev

Not sure if the dev package is needed, but that worked for me.

Hm, that's strange. I've built this on 18.04 without issue. glib is also explicitly marked as a dependency here:

LCMCore.jl/deps/build.jl

Line 26 in 3d10f74

glib = library_dependency("glib", aliases=["libglib-2.0-0", "libglib-2.0", "libglib-2.0.so.0"], depends=[python], validate=cflags_validator("glib-2.0"))

and we have an automated built step to install libglib2.0-dev from apt here:

LCMCore.jl/deps/build.jl

Line 30 in 3d10f74

provides(AptGet, Dict("python-dev" => python, "libglib2.0-dev" => glib))

so it shouldn't be necessary to install it manually. Do you have a log of the original build error?

[rdeits]

Any updates on this? I noticed your PR #43 is still open, and I want to make sure I'm not just ignoring it 🙂

Same on Windows:

[rdeits]

Yeah, Windows is known not to work. See also: #2

The right solution would be to use https://github.com/JuliaPackaging/BinaryBuilder.jl to provide LCM binaries and be done with it. I'm afraid I don't have time to do that now, though.

Just to confirm the build issue on a fresh ubunu 18.04 installation, manually installing with sudo apt-get install libglib2.0-dev worked.

This continues to confuse me. I've still never seen the issue on any of my machines, but it's clearly happening. I've merged #43 since it seems prudent to help future users avoid the problem.

If you want to help debug whatever the underlying issue is, I'd be very interested to see what:

using BinDeps
BinDeps.debug("LCMCore")

reports (without manually installing libglib).

BTW, on 1.0 you'll need JuliaPackaging/BinDeps.jl#389 to get BinDeps.debug working.

Hi @rdeits, ah sorry -- just came across this now again. I have not seen this problem again myself. Also not seeing this on many Travis and JuliaCIBot tests. We just heard that this was an issue again recently (cc @jim-hill-r). Maybe keep the issue open for a little while more as people move from 16.04 up to 18.04? I will check this again when I have a fresh system to test on.

[rdeits]

Sure, no problem. It might be time for me to try the BinaryBuilder approach again, too.

Hi, I ran into this again, but with a slightly different error.
The output of BinDeps.debug("LCMCore")

build LCMCore gives this error:
