Hi Lu, Liu,
You are both seeing the same problem, that __init_array_end is missing
when you try to load CMPFlex. The __init_array_end symbol is supposed to
be provided automatically by the linker. I am not sure why the symbol is
not being defined. I suspect it is a bug in ld, as it should not be
possible to stop ld from emitting the symbol. Another SimFlex user
reported a similar problem using Fedora Core 3 linux. We still have not
gotten a Fedora Core box set up here to try to chase this error down.
Please try using the attached makefile.def. It differs from the file in
the release in that it shuts off the "whole archive" option at the end of
the link command line, which may cause the linker to behave better. You
will need to edit it to put in your paths, as described in the getting
started guide.
Also, please let me know which Linux distribution you are using.
