Compiling demos on Mac OS X 10.4.2

CAS

I've just started experimenting with Ice for possible use in a robotics project. I successfully compiled and ran the demos on Linux but am having trouble linking under Mac OS X 10.4.2. When I run make in the demo directory, I get the output below. I've set up the environment variables correctly, as far as I can tell, so I don't know why the linker is complaining.

% make
making all in IceUtil
making all in workqueue
rm -f workqueue
c++ -Wl,-executable_path,/Users/claude/Applications/Ice-2.1.2/bin -g -ftemplate-depth-128 -Wall -D_REENTRANT -L/Users/claude/Applications/Ice-2.1.2/lib -o workqueue WorkQueue.o -lIceUtil -lpthread
/usr/bin/ld: Undefined symbols:

Welcome to the forums! Which compiler do you use? The Mac OS X binary package was compiled with GCC 3.3 so you should use it to compile the demos (you can select which GCC version you want to use on Mac OS X with the gcc_select utility).

We don't support GCC 4.0 which has a bug that prevents Ice to compile. GCC 4.0.1 fixes this problem but it's not publicly available yet on Mac OS X.

Let us know if this doesn't help!

Gcc 3.3

Thanks for the advice. I used gcc_select to switch to version 3.3, as you suggested, but I still get errors:

Default compiler has been set to:
gcc version 3.3 20030304 (Apple Computer, Inc. build 1809)

Did you do a "make clean" before to run "make" again after selecting the new compiler?

make clean

"make clean" worked. Sorry, that was a silly mistake. All the demos are working now. Thanks for the very quick responses.
