+# Creating shared libraries on AIX involves lots of commands. While there is
+# the ld-wrapper supporting the '-soname' flag already, it also is necessary
+# to create the list of exported symbols from all the local object files only,
+# because with the -bexpfull linker flag we would export symbols from static
+# objects found in libc.a too, which should be privately linked into
+# subsequent shared libs instead of importing them from current sharedlib.
+
+# Also, -bexpfull may trigger this AIX 7.1 kernel bug:
+# https://www-304.ibm.com/support/docview.wss?uid=isg1IV39558
+
+# Example to use this helper script, in combination with ld-wrapper:
+# gcc -shared -soname=lib.so.1 -o lib.so *.o -Wl,-bexport:`mkexpfile *.o`
