Ohw sorry, sure: The one I've posted at libtool mailing list[1][2] as well as in the IBM AIX Developers forum[3], and recently to the binutils mailing list[4]. While the big agreement on that variant is still not there - maybe because of less interest (there's not much response anywhere), I've implemented that in Prefix now for both prove-of-concept as well as to identify possible problems. How I prefer doing "shared libraries" with "soname" on AIX now is: *) Create the shared object "shr.o" (using '-G' linker flag). *) Set the LOADONLY flag for "shr.o" (using 'strip -e'). *) Create the Import File "shr.imp", containing - this header line, being the "soname" emulation: #! libNAME.so.1(shr.o) - another header line telling the bits used: # 32 or # 64 - the list of symbols exported. *) Create the archive library "libNAME.so.1.2.3" from both "shr.imp" and "shr.o". *) Create the symlinks as usual: libNAME.so.1 -> libNAME.so.1.2.3 libNAME.so -> libNAME.so.1.2.3 *) Create the static library archive "libNAME.a" from static objects.
