Hi, again.

Yes. Here's the breakdown of the more intereting option.

-shared   create a shared lib.
-whole-archive use *all" objects in the following archive.
-no-whole-archive the opposite to the above.

The reason for the "whole-archive" thing is to use *ALL* functions ( objects ), that are in
libcpml_ev6.a, but only those needed in libots.

The -soname switch tells the linker, to set the SONAME field in the shared lib to the specified
name. That way, you can use -lcpml and have the link libcpml.so point to the real thing - which
is libcpml_ev6.so, in our case.

Oh yes, adjust that. Also, don't forget to run the obvious ldconfig(8) after creating the new
shared lib. You may strip(1) it first, for space-saving.

That'a a support lib needed by GCC and friends. This looks like, you have not setup
you CCC config-file correctly. Check the following file:

/usr/lib/compaq/ccc-"your_version"alpha-linux/bin/comp.config

The path's in there should reflect your system. You can create this file, after you edited
the script create-comp-config.sh to reflect your system. It's also in the above directory.
This script is the setup-script for the Compaq compiler ( and typically run at rpm postinst, IIRC ).

If you have trouble setting up the compiler, let me know. It's a bit lengthly, but I can
provide the setup for you.
