you can't build multitarget MinGW using 32-bit OS

[anatoly techtonik]

I am on 32-bit system, trying to build 32-bit toolchain and fetch

files with command

  https://github.com/mingwpy/mingwpy#build-32-bit-toolchain

which fails with

-> Checking OS bitness... 32-bit
-> Checking OS type... MINGW32_NT-6.0
-> Checking for installed packages... done
you can't build multitarget MinGW using 32-bit OS. terminate.

I traced it to

  https://github.com/niXman/mingw-builds/blob/master/build#L336

But it doesn't explain what's going on there. So why I can't build it?

You have to build with the option --no-multilib.

Did you encounter this error messeage with the --fetch-only command? If yes, then add the --no-multilib option to the command line.

[anatoly techtonik]

Yes, it is with --fetch-only. --no-multilib makes it pass, but should it be added into instruction for building 32-bit toolchain?

[carlkl]

Be aware, that the build can take hours with an older system. I will update the docu once its builds sucessfully on a 32 bit system.

So far it still downloads the files.
