Not exactly. ld on AIX 4.2+ has the -bexpall flag to export everything, but
this flag does bad things on shared libraries, and should only be used on
executables.
I sent you patches for AIX before. These are the rules I use in our
Makefile. They work on all platforms:
$(SHRCRYPTO): lib/$(LIBCRYPTO).a
ld -r -o $(LIBCRYPTO).o $(ALLSYMSFLAG) lib/$(LIBCRYPTO).a
-nm -Pg $(LIBCRYPTO).o | grep ' [BD] ' | cut -f1 -d' ' >
$(LIBCRYPTO).exp
$(CC) $(SHAREDFLAG) -o $@ $(LIBCRYPTO).o
$(SHRSSL): lib/$(LIBSSL).a $(SHRCRYPTO)
ld -r -o $(LIBSSL).o $(ALLSYMSFLAG) lib/$(LIBSSL).a
-nm -Pg $(LIBSSL).o | grep ' [BD] ' | cut -f1 -d' ' > $(LIBSSL).exp
$(CC) $(SHAREDFLAG) -o $@ $(LIBSSL).o $(SHRCRYPTO)
The ALLSYMSFLAG is "-bnogc" for AIX, which turns off garbage collection
and bypasses the step where the linker removes unreferenced objects. For
Linux the flag is "-whole-archive", for Solaris "-z allextract". Obviously
the contents of "lib/$(LIBXX).a" is assumed to be PIC code. I haven't
configured this on any other platforms recently, so I don't have the
corresponding flags, but it shouldn't be hard to find them.
