Got the same problem as JohnRobson:

sip: Deprecation warning: the -B flag is deprecated
Error: Unable to create the C++ code.

The issue is the '-f' flag in combination with the deprecation warning (which -f turns into an error). Unfortunately it is hardcoded in the configure script. Patching it like this, helps for me:

Actually, since the day before yesterday (14th of October 2019) the "sip"-Package got flagged outdated. Does it make sense to install the 4.19.16-2 version of "sip" or have we to accept that this isn't working now. What do you think?

@esdrasedu: Thanks, it helped me too. For noobs like me, to get the package you can download it from here: https://archive.archlinux.org/packages/s/sip/ I followed the advice and tried it with 4.19.16-1 (couldn't find the 2). sip-4.19.16-1-x86_64.pkg.tar.xz Downgraded with sudo pacman -U ~/Downloads/sip-4.19.16-1-x86_64.pkg.tar.xz. Might work with sudo pacman -U https://archive.archlinux.org/packages/s/sip/sip-4.19.16-1-x86_64.pkg.tar.xz too but haven't tried.

esdrasedu thank you very much,very useful!

@zorki, @Attius_Sullivan and @0003c9fe I have same issue. It in my case is becase sip version 4.19.19-1 isn't compatible with python2-pyqt4 version 4.12.3-3! I installed sip version 4.19.16-2 and seems working well

Having the same error.

@0003c9fe I've got the same problem here (arch, linux-lts kernel)

I'm getting the same error as others had before, but the fix for that seemed to be changing the PKGBUILD, which seems to have been corrected since then, so I'm not sure why it isn't working.
