This is from the man page for GNU ld:
The linker will search an archive only once, at the location where
it is specified on the command line. If the archive defines a sym-
bol which was undefined in some object which appeared before the
archive on the command line, the linker will include the appropri-
ate file(s) from the archive. However, an undefined symbol in an
object appearing later on the command line will not cause the
linker to search the archive again.
See the -( option for a way to force the linker to search archives
multiple times.
You may list the same archive multiple times on the command line.
I didn't know about the "-(" and "-)" options. Perhaps the ld
commands generated by the ocaml tools should use this to make library
order less error-prone?
