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`

```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

```

log

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?

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

- remove: PackageCompiler , UnicodePlots
- `pkg> gc`

Thanks to all for the comments.

My Linux and gcc versions are:

```julia
$ 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:

```julia
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:

```julia
$ ./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?

```julia
$ ./hello

signal (11): Segmentation fault
in expression starting at no file:0
unknown function (ip: 0xffffffffffffffff)
main at ./hello (unknown line)

it is working on `buildir` ? ( no copy … )

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/`.

My builddir also has a full bunch of files:

```julia

If I copy all the files under builddir into `/home/user/Software/julia-1.0.3/bin/` and run hello under `/home/user/Software/julia-1.0.3/bin/`, then it sort of works:

```julia
$ pwd
/home/user/Software/julia-1.0.3/bin
[manjaro bin]$ ./hello
hello, world
sin(0.0) = 0.0

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

```julia
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

```

good news 🙂

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](https://julialang.org/downloads/platform.html) - with the default linux instructions.

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

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.

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.

I agree that it should not segfault, 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](https://github.com/JuliaLang/julia/issues/28636) )
- Multiple julia versions? ( [How to set path after running juliac.jl?](https://discourse.julialang.org/t/how-to-set-path-after-running-juliac-jl/14025) )
- bad cache somewhere ?
- LD\_LIBRARY\_PATH problems?
- some strange problems? ([https://github.com/JuliaLang/PackageCompiler.jl/search?q=hello&type=Issues](https://github.com/JuliaLang/PackageCompiler.jl/search?q=hello&type=Issues) )
