MacOS 10.3 compile issues

StuartA

I'm trying to port a client Ice app to MacOSX 10.3.9 (running inside
pearpc). I'm not traditionally a Mac developer.


System setup:

Mac version: 10.3.9
xcode 1.5
november2004gccupdater_7k579 (same behaviour before update)
Ice version 2.1.0

I've installed the Ice-mac binaries. I'm having trouble getting
anything to compile that includes <Ice/Ice.h>. Including the
demos.

Similar behaviour with 2.95, 3.1. I'm not familiar enough with
gcc-mac to work this one out. Any hints?

I suspect this is caused by Ice being installed in /usr/include. After a bit of search on Google, I found this post: http://lists.apple.com/archives/unix-porting/2004/May/msg00068.html. It appears that gcc automatically adds extern "C" for some header files. Can you try to move Ice to /opt/Ice-2.1.0 for example and see if this solves the problem?

Benoit.

Benoit,

You are correct. Thankyou very much!

Another example of great support from ZeroC
