Hi and welcome to devnet, AFAIK from the Chromium project, builds for 32bit Macs have ended by the end of 2014. Snow Leopard was the last version supporting 32 Bit processors.

@SGaist Oh, I see where to do that. Thanks. I think that last part makes for a solution.

@Karen-Morrissey I think because when you did ./configure to look for needed libraries, it first found those in /usr/lib64. Why not to force the configure to use those for 32bit by adding -L /path/to/lib/32bit -lpthread -lm -lc to your configure command

Hi, If you want to build KDSOAP for 32bit then just use a 32bit Qt build. You'll avoid all these troubles

Hi, for 32bit you will need to compile Qt on your own. We provide the most common derivates (64bit and ARM) only as otherwise the packages would simply become to big. For reference you can find the documentation here: http://doc.qt.io/qt-5/winrt-support.html#building-from-source The mkspec of choice would be winrt-x86-msvc2013 then.

@sierdzio said: Thanks a lot for the clarification.
