Hi, all,
Pierre Mathieu had managed to compile SIP under Macintosh.
He said he had to change a linker flag in Makefile.am
In the future we must automate this based on results of
the configure script.

Thank you for your response.
I didn't know the meaning of the "-no-undefined " modifier of the ld
command in the Makefile.am .
Although the compiler is gcc on the Mac, ld is not the same as on
Linux.
To let undefined symbols at the link time, the option is then
"-undefined warning " which transforms errors in warnings. On 10.3 it
can be used "-undefined dynamic_lookup ".
In any case it is working very well now.
I thank you again for your help and for you great work in SIP.
best regards
Pierre Mathieu
