Building Error in Windows

[mes9]

When I try to build the GLMNet.jl it tells me that the file is not found. I dug around and it looks like the problem is inside the build.jl file:

pic = @windows ? "" : "-fPIC"
run(`gfortran -m$WORD_SIZE -fdefault-real-8 -ffixed-form $pic -shared -O3 glmnet5.f90 -o libglmnet.so`)

and when the run( ) line is read, under windows it will change $pic to '' instead of an actual blank, which messes up the build. When I removed the $pic from that line, it built fine

Supposedly mingw is available on appveyor, perhaps it is worth enabling it?

Hey. I was trying to build GLMNet for Julia on Windows and I get following errors .

[amellnik]

@mogit You can install gfortran via Msys2 by following the instructions here: https://github.com/orlp/dev-on-windows/wiki/Installing-GCC--&-MSYS2

Hello,

I'm facing the exact same problem as @mogit. I have tried @amellnik's solution but it hasn't produced any change in the error.

[amellnik]

@raphaelsaavedra Did you also add the location of gfortran.exe to your path? It's something like C:\msys64\mingw64\bin.

[raphaelsaavedra]

Hey @amellnik, thanks for the quick answer. Yes, I have added the location of both mingw64 and 32 to my path.

When trying to run gfortran on MinGW, the following error occurs:

I have followed all instructions in the link you provided before. I'll also add I'm working on Windows 7. My friend who has a mac had no issues.

[amellnik]

That's expected. You should see the same thing if you run it from powershell/cmd in windows if you also added it to the windows (not Msys2) path. If that's the case then you should be able to run julia and try to add GLMNet again.

@amellnik I managed to make it work by running Julia as administrator. Apparently my user did not have the necessary permissions to run gfortran while building GLMNet? Either way thank you for the help.

@amellnik Thanks! I had the same problem, and the same solution.

Hello @amellnik,
I'm also having the same problem as @mogit, but I'm using a Mac. Is there any suggestions? Thank you!

[amellnik]

Hi @RuilinOuyang -- as it happens I just became a Mac user myself. You can install gfortran via Homebrew with brew install gcc and everything should work fine after that.

[RuilinOuyang]

@amellnik Thank you! I did what you said, it's working now.

Distributing compiled dependencies would be a great help to users.
