AOT compiled hello.jl core dump

[LeoK987]

Compiled through, but execution got core dump. Any idea?

Can you give more info about your system? ( linux version , gcc version ? )

On clean docker julia environment this example working for me:

docker run -it julia:1.0.3 bash

apt-get update && apt-get install -y build-essential
julia -e 'using Pkg;Pkg.REPLMode.pkgstr("add UnicodePlots;precompile");using UnicodePlots'
julia -e 'using Pkg;Pkg.REPLMode.pkgstr("add PackageCompiler;precompile");using PackageCompiler'
cd $(julia -e 'print(abspath(joinpath(dirname(Base.find_package("PackageCompiler")), "../examples")))')
time julia -e 'using PackageCompiler;  build_executable("hello.jl")'
cd builddir
./hello

It looks like you’re supplying a potentially different hello.jl than ships with PackageCompiler. Can we see the source/an MWE of what’s in that file, if it differs from the default one?

[ImreSamu]

@LeoK987

signal (11): Segmentation fault

maybe after upgrading julia - creating a clean state is very important

• remove: PackageCompiler , UnicodePlots
• pkg> gc

see :

Segfault on Julia 1.0.1 (but not on 1.0.0)?

[LeoK987]

Thanks to all for the comments.

My Linux and gcc versions are:

$ gcc --version
gcc (GCC) 8.2.1 20181127
Copyright (C) 2018 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO

$ uname -a
Linux manjaro 4.19.13-1-MANJARO #1 SMP PREEMPT Sat Dec 29 15:43:56 UTC 2018 x86_64 GNU/Linux

I copied the hello.jl from PackageCompiler:

module Hello

using UnicodePlots

Base.@ccallable function julia_main(ARGS::Vector{String})::Cint
    println("hello, world")
    @show sin(0.0)
    println(lineplot(1:100, sin.(range(0, stop=2π, length=100))))
    return 0
end

end

The packages of PackageCompiler and UnicodePlots were added yesterday under the same julia version. I just did a gc under pkg and recompiled hello.jl.

Actually, when I first run hello, I got a message saying hello.so not found:

$ ./hello
ERROR: could not load library "/home/user/Software/julia-1.0.3/bin/hello.so"
/home/user/Software/julia-1.0.3/bin/hello.so: cannot open shared object file: No such file or directory

So then I copied hello.so from builddir into /home/user/Software/julia-1.0.3/bin/, then when I ran hello, I got a core dump. Is there something wrong with my setting?

$ ./hello

Yes, I run hello under buiddir, but it’s not taking the hello.so there for some reason, and complains about the lack of hello.so under /home/user/Software/julia-1.0.3/bin/.

There must be something wrong with my julia env setting then. In my .bashrc I have set these. Something not appropriate?

export JULIA_DIR=/home/user/Software/julia-1.0.3
export JULIA_BINDIR=$JULIA_DIR/bin

export PATH=$JULIA_BINDIR:/home/user/Software/VSCode-linux-x64/bin/:$PATH

export LD_LIBRARY_PATH=./:$JULIA_DIR/lib:$LD_LIBRARY_PATH

[ImreSamu]

good news

@LeoK987

There must be something wrong with my julia env setting then.

I am only a (julia)beginner - and I am mostly using Docker environment.
my simple advice:

• Check my (manjaro)Dockerfiles ( see “FROM jonathonf/manjaro” … )
• and/or check the https://julialang.org/downloads/platform.html - with the default linux instructions.

[LeoK987]

@ImreSamu, thanks very much for the kind help!

[ImreSamu]

if everything is working - please set a “solved” flag in the forum - so others can see the solutions.

[LeoK987]

It’s not working yet. I still can not run hello from under builddir if I don’t copy all the files into JULIA_BINDIR.

[jpsamaroo]

That’s because it’s failing to load its shared libraries, which for some reason becomes a segfault, not a linker error. Maybe a good idea to file an issue on PackageCompiler’s Github, and provide a link to this discussion for context. At the very least, a linker error would be preferred to a segfault.

[LeoK987]

I agree that it should not segfault, but I don’t understand why it works for @ImreSamu’s setup.

[ImreSamu]

@LeoK987

but I don’t understand why it works for @ImreSamu’s setup.

What we know: On clean (Manjaro) Docker environment - it is working.
Question: What is the differences?

• only you can find this - because I can’t replicate the error

Some hint:

• Can you replicate your error in (Manjaro) Docker environment? ( add julia files, settings, .bashrc )
• Testing PackageCompiler is OK ? ( pkg> test PackageCompiler )
• What is the result of :
  • # export | grep -i julia
  • # set | grep -i julia
• What is your full $PATH?
  • # echo $PATH

If you don’t see any problems - try cleaning your environment:

• backup !!!
• remove ~/.julia ; ~/.juliarc.jl
• remove all julia versions
• check no libjulia in your system:
  • `find / -name “libjulia*”
• clean/verify environment variables, $PATH
• reinstall only Julia-v1.0.3
• add packages
• your testcase is working?

it can be a complex issue:

• JULIA_BINDIR? ( v1.0.0 segfaults on macOS X if JULIA_BINDIR set wrongly · Issue #28636 · JuliaLang/julia · GitHub )
