Error when linking after finish_freezing

This problem only occurs on SunOS.

Problem

On SunOS, I receive an error message like the following, when I link after I haveve executed finish_freezing:

cc -o driver -O -DWORKBENCH -I $EIFFEL4/bench/spec/$PLATFORM/include
obj1.o obj2.o obj3.o obj4.o Einit.o Evisib.o Eskelet.o Eplug.o
Econform.o Ecall.o Edispatch.o Efrozen.o Epattern.o Eoption.o Emain.o
$EIFFEL4/bench/spec/$PLATFORM/lib/libwkbench.a -lm

ld: $EIFFEL4/bench/spec/$PLATFORM/lib/libwkbench.a: warning: table of
contents for archive is out of date; rerun ranlib(1)

make: *** [eiffelbase] Error 2

(This output has been formatted. The problem only occurs on SunOS, so in this case the $PLATFORM variable will always have value sparc. If you are using ISE Eiffel 3, the environment variable will appear as EIFFEL3 rather than EIFFEL4; this also applies to the rest of the present page.)

Fix

Execute the following commands:

ranlib $EIFFEL4/bench/spec/$PLATFORM/lib/libwkbench.a
ranlib $EIFFEL4/bench/spec/$PLATFORM/lib/libruntime.a

and execute a ranlib on the following files as well (depending on your installation):

EiffelVision
$EIFFEL4/library/vision/spec/$PLATFORM/lib/Xt.a
$EIFFEL4/library/vision/spec/$PLATFORM/lib/motif_Clib.a

EiffelLex
$EIFFEL4/library/lex/spec/$PLATFORM/lib/lex.a

EiffelNet
$EIFFEL4/library/net/spec/$PLATFORM/lib/libnet.a
$EIFFEL4/library/net/spec/$PLATFORM/lib/libwnet.a

Discussion

This problem is not specific to Eiffel, but has to do with the handling archives on Sun platforms: the path is hard coded so each time you're moving the achives, you must run ranlib again.

After doing that, you will have to run make again in the EIFGEN/W_code directory to finish the C compilation.

It is possible that during C compilation you get a message that looks like:

make: *** No rule to make target `two_way150F.o'.  Stop.

This occurs because the precompilation erases the C files and objects files once the intermediate objects are created and the process doesn't expect any problem during the C compilation.

You have two options:

Start the precompilation from scratch, by removing the EIFGEN directory, and redo the entire precompilation process.

Modify the Makefile in the EIFGEN/W_code directory: remove the dependencies for the final linking by replacing `driver: F1/Fobj1.o .... Makefile' by `driver:'. Now run make again, what will do the linking directly.
