Package Compiler doesn't download required artifact

General Usage
1

I am trying to precompile LanguageServer using PackageCompiler by typing this into REPL

using PackageCompiler; create_sysimage([:LanguageServer,:SymbolServer], sysimage_path="./julials.dll", precompile_statements_file="./tracecompilelsp.jl")

It seems to compile until i got this error

ERROR: IOError: could not spawn setenv(`'C:\Users\mhaikala\.julia\artifacts\fdff308295487f361ef6e8dc2d27f5abe8a6eee9\mingw64\bin\g++.exe' -m64 -march=x86-64 -shared '-LC:\Users\mhaikala\AppData\Local\Programs\Julia-1.8.5\bin' '-LC:\Users\mhaikala\AppData\Local\Programs\Julia-1.8.5\bin' -o ./julials.dll -Wl,--whole-archive 'C:\Users\mhaikala\AppData\Local\Temp\jl_F0VQnYBO3g.o' -Wl,--no-whole-archive -ljulia -ljulia-internal -lopenlibm -Wl,--export-all-symbols`,["PATH=...long-list-of-my-path-variable"]: no such file or directory (ENOENT)

So i look into ~/.julia/artifacts/fdff308295487f361ef6e8dc2d27f5abe8a6eee9/mingw64 and found out there is only ‘opt’ folder but no ‘bin’ folder. I have reinstalled PackageCompiler and tried again but no success.

My julia config is this

I get a similar error running your code, but not when I remove the option precompile_statements_file="./tracecompilelsp.jl". Are you sure that PackageCompiler can find that file on your system? And if so, what are its contents?

Running create_sysimage([:LanguageServer,:SymbolServer], sysimage_path="./julials.dll") eventually results in the error:

ld: warning: could not create compact unwind for _julia_YY.244_63412: stack subq instruction is too different from dwarf stack size
ld: warning: could not create compact unwind for _julia_YY.load_coreYY.23_76333: stack subq instruction is too different from dwarf stack size

Thanks, @dilumaluthge! That was my issue.

It contains what should be compiled for the sysimage. It contains a lot precompile statements
like some of these

precompile(Tuple{Type{Base.Multimedia.TextDisplay}, Base.PipeEndpoint})
precompile(Tuple{Type{REPL.Terminals.TTYTerminal}, String, Base.PipeEndpoint, Base.PipeEndpoint, Base.PipeEndpoint})
precompile(Tuple{typeof(Base.something), Nothing, Base.PipeEndpoint})
precompile(Tuple{typeof(Pkg.API.instantiate)})
precompile(Tuple{typeof(Base.deepcopy_internal), Any, Base.IdDict{Any, Any}})
precompile(Tuple{typeof(Core.Compiler.eltype), Type{Array{UInt64, 1}}})
precompile(Tuple{typeof(Base.deepcopy_internal), Tuple{UInt64}, Base.IdDict{Any, Any}})

to generate it I followed direction from this post

I’m sure PackageCompiler can found it. I have tried making a symbolic link for
~/.julia/artifacts/fdff308295487f361ef6e8dc2d27f5abe8a6eee9/mingw64/bin to point at my msys2 installation that has g++ and it manages to build the image. But when i use it Julia can’t load it.

I had the same issue. I just removed the incomplete artifact directory, removed and added PackageCompiler in Pkg. Then it downloaded the complete artifact when I was compling the next time.
