IceTouch examples Linker error

SiegfriedHora

Hi,

tried to compile one of the IceTouch examples (Ice/hello) and got following error message.
Anybody who can help ?

Hi,

Welcome to the forums!

This warning:

ld: warning: in /opt/IceTouch-1.0/lib/libIceObjC.dylib, file is not of required architecture

indicates that you are compiling the demo with an architecture that is different from the IceObjC library. Most likely, you are compiling the demo in 64 bits mode whereas the library is 32 bits (you can use the "file" utility to figure out the architecture of a given library/object, e.g.: "file /opt/IceTouch-1.0.0/lib/libIceObjC.dylib").

You have 2 options:

• you change the demo build system to compile the demos with the right architecture. To do this, edit the config/Make.rules.Darwin file from the demo distribution and add "-arch i386" to the CFLAGS/CXXFLAGS variables.
• you download the IceTouch source distribution and rebuild Ice Touch using your default architecture.

Let us know if you need further help with this!

Cheers,
Benoit.

Thanks,

option 1 helped.
Now example compiles.
