Re: [julia-dev] Building Julia from source in Windows

[Jameson Nash]

This is a better question for julia-users.

The most reliable compilation environment at this point seems to be cygwin:

https://github.com/JuliaLang/julia/blob/master/README.windows.md#cygwin-to-mingw-cross-compiling

The environment seems to believe you are using the msys-gcc compiler, rather than the mingw-w64-gcc compiler. Perhaps your PATH variable isn't setup correctly?

(unzipping should work fine; that's how i've usually installed it).

Hi,

 

I’m trying to build Julia from source in Windows.  I’m following the instructions described in the README.windows.md here:

 

https://github.com/JuliaLang/julia/blob/master/README.windows.md

 

However, I’m getting stuck on step 6.iv where I begin the build.  I get the following error in msys:

 

$ make -j 4

/home/t-satasn-win8/julia/Make.inc:432: *** "cannot build julia with msys-target compilers. please see the README.windows document for instructions on setting up mingw-w64 compilers".  Stop.

 

I noticed that the mingw-builds installer doesn’t correctly install and quits with error message “ERROR res”.  It claims it installed successfully but there are barely any files in there.  Instead, I downloaded from the source and unzipped it and directly moved it to my C:\ drive.  I have also tried using the MinGW-w64 installer and using a newer 4.9.2 version, but that didn’t work either.

 

Would anyone be able to help me on this problem?  Thanks!

 

Kind regards,

Sayeed

This is actually very much in flux right now. Whether Cygwin or a modified MSYS2 build using a different toolchain than what we currently recommend in the master version of README.windows.md is being determined in https://github.com/JuliaLang/julia/pull/11705. If you're willing to check out that branch and test things, it would be appreciated.
