Hello,
I'm trying to build the "whole thing" (TM) on AIX and I get a linker
message that I don't understand:

Adding '-lz ../structure/libsgstructure.a ../props/libsgprops.a' helps,
'-lz' for the ".gz..." symbols, 'libsgprops.a' for all the
".SGPropertyNode" stuff and 'libsgstructure.a' for the rest.
But: Why do I need to add this only on AIX !???
Martin.
P.S.: This is not the end of difficulties, simgear/io/decode_binobj
makes even more trouble ....
