Thanks Tony, I'm finishing a .bat script to automate the task and that includes building also a slightly modified 'prepare-julia-env.bat'. I'll call it 'redo-julia-env.bat'
To finish it, I need two pieces of information: First, in the prepare-julia-env.bat' script, julia is used with a --build option which I cannot find documented. Here is the line with the issue (the vars are the correct dirs, etc...): cd "%JULIA_HOME%..\share\julia\base" && ^ "%JULIA%" --build "%JULIA_HOME%..\lib\julia\sys0" sysimg.jl && ^ "%JULIA%" --build "%JULIA_HOME%..\lib\julia\sys" -J sys0.ji sysimg.jl && ^ popd && pushd "%cd%" ) However, when I run Julia with that switch I get an error. (Perhaps before the 'prepare-julia-env.bat' script is run for the first time in installation, there is that option available...?) D:\Math\Julia-0.3.0-rc1\bin>julia --version julia version 0.3.0-rc1 D:\Math\Julia-0.3.0-rc1\bin>julia --build ERROR: unknown option: --build in process_options at client.jl:288 The second issue is that I don't have the 'sys0' file also shown in that line, but since I don't know what --build does, sys0 is perhaps being built in that command... So, in the end I think the issue is lacking the --build command option; Appreciate any help. TIA and regards. Jose
