Build a universal lib on OSX ?

[BigTick]

Hi,

Is there any way to build a universal (Intel/ppc/32-bit/64-bit) OSX binary ? Or do we have to build all the individual libs and combine them with lipo ?

Currently you have to build for the different archs manually and then combine the builds with lipo.
Of course it would be great to have some script for this...

Actually you can directtly build libs that have all the architectures you
THis is the config i use

Code: Select all

Great! I would have thought that this does not work, but apparently it does
