Error trying to build system image on Windows

General Usage
1

I’m trying to build a Julia system image on Windows 10.
(following http://docs.julialang.org/en/stable/devdocs/sysimg/#building-the-julia-system-image)

First I installed gcc:

Pkg.add("WinRPM")
using WinRPM
WinRPM.install("gcc")

Then I ran build_sysimg:

include(joinpath(JULIA_HOME, Base.DATAROOTDIR, "julia", "build_sysimg.jl"))
build_sysimg(force=true)

This is the (summarised) output, ending with error:

INFO: Building inference.o
...

How can I diagnose the problem?

The build_sysimg script might need some slight tweaking to the link command that it runs to account for changes in the gcc packaging from WinRPM. Try WinRPM.install("winpthreads-devel", yes=true) and see if that helps.

It works!

INFO: Linking sys.dll
INFO: System image successfully built at C:\Temp\Julia-0.5.1-m4\bin\..\lib\julia\sys.dll
INFO: Julia will automatically load this system image at next startup

Thank you very much!

Can I safely ignore these warnings after INFO: Building sys.o:

I think yes, they are always there. My experience over the last six months.

@tkelman today, I tested it on native windows 7 and windows8.1 (VirtualBox). I got error

It’s not working :frowning: Maybe, what are the requirements for pc?

What happens if you run
C:\Users\M\.julia\v0.5\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\gcc.exe -LC:\Users\M\Desktop\Julia-0.5.0\bin -shared -ljulia -lssp -o C:\Users\M\Desktop\Julia-0.5.0\bin\..\lib\julia\sys.dll C:\Users\M\Desktop\Julia-0.5.0\bin\..\lib\julia\sys.o
from a command prompt? This may not work any more with Julia 0.5.0 and the latest WinRPM packages, 0.5.1 might work better.
