As the error message says, the compiler you're using cannot build for the specified or automatic target. You need to change one or the other.

If you want a 64-bits Firefox, you need to add:
  ac_add_options --target=x86-64-pc-mingw32
  ac_add_options --host=x86-64-pc-mingw32

to your mozconfig, or use a 64-bits MINGW shell.

If you want a 32-bits Firefox, you need to replace the Visual Studio/VC/bin/amd64 path in $PATH with Visual Studio/VC/bin (or remove it altogether, configure should be able to find it)

I'll leave this bug open, because there might be something we can change to configure to make things smoother (and in your case it would mean building a 32-bits Firefox by either adjusting the compiler path to pick the 32-bits compiler, or add flags to build for 32-bits)

Adding the above two lines to the mozconfig didn't change any of the errors, so instead of using (x64) MinGW Shell, I used a different MinGW Shell to build the source this time. 

However, build procedure interrupted again by an error:-

Unable to build even after doing what is suggested at the site : https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Windows_Prerequisites
I keep facing the same issue as given above.

Could really use some help right now !!


Thanks,
Aseem
It looks like you don't have write permissions to the temporary directory wherever configure is trying to create temporary files.  Where is your temporary directory set to?
Severity: blocker → normal

Comment 7

I had the same issue, and added 

ac_add_options --target=x86_64-w64-mingw32
ac_add_options --host=x86_64-w64-mingw32

to my mozconfig, which has solved my problem. Also I advice to run 
./mach bootstrap 
before you run 
./mach build 
because cargo and rustc were missing.

How recommended above added 
ac_add_options --target=x86-64-pc-mingw32
ac_add_options --host=x86-64-pc-mingw32
to mozilla-source/mozilla-central/configure
and used both batch with shells - start-shell-msvc2015 and start-shell-msvc2015-x64

then added other options
ac_add_options --target=x86_64-w64-mingw32
ac_add_options --host=x86_64-w64-mingw32
to mozilla-source/mozilla-central/configure
and used again both batch with shells - start-shell-msvc2015 and start-shell-msvc2015-x64

In all cases got the same error: Target C compiler target CPU (x86_64) does not match --target CPU (i686)

This contradicts what you say is in your mozconfig. In fact, if that's your full config.log, that implies your mozconfig is not used, otherwise, your log would start with "Adding configure options from ...."

Thanks for your reply, Mike.
I have tried to run build again and direct console output to file. And it differs from that output which in config.log. Config.log content remains the same like in my previous comment. 

I have used mozilla-source/mozilla-central/configure file including this:
#!/bin/sh
SRCDIR=$(dirname $0)
TOPSRCDIR="$SRCDIR"
export OLD_CONFIGURE="$SRCDIR"/old-configure
which python2.7 > /dev/null && exec python2.7 "$TOPSRCDIR/configure.py" "$@" || exec python "$TOPSRCDIR/configure.py" "$@"
ac_add_options --target=x86_64-w64-mingw32
ac_add_options --host=x86_64-w64-mingw32

and ran shell by start-shell-msvc2015-x64.bat

It is console output:
 0:01.07 c:\mozilla-build\mozmake\mozmake.EXE -f client.mk -s configure
 0:04.03 cd c:/mozilla-source/mozilla-central/obj-i686-pc-mingw32

This is not where ac_add_options should be placed. Create a .mozconfig file with the ac_add_options lines in it.

I met the same problem,and I added a new file named .mozconfig which  ac_add_options lines was written to C:\mozilla-source\mozilla-central.Then mach build.Soved this problem perfectly.

same problem i faced today
I simply went to window powershell
write this command  rustup target add i686-pc-windows-msvc
again run mach build
and things working for me
