[Ecls-list] fatal: relocation errors on Solaris x86 and OpenSolaris 64-bit.

[Juan Jose Garcia-Ripoll]

Some more insight or some more confusion, I do not know.

Using -Wl,-ztext we can force the linker to emit a warning about text
relocations. The advantage is that it shows the actual symbols. For an ECL
with an external GMP (not its own) it shows the ones below. I would say they
are pretty harmless, aren't they? GMP has the same relocation "problems" so
to say.

;;;   gcc -o "libecl.so" -L"/export/home/jjgarcia/tmp/opensolaris64/"
"c/main.o" "c/all_symbols2.o" "liblsp.a" "libeclmin.a"
 "-Wl,-R,/export/home/jjgarcia/lib/" -dy -G  -fPIC -Wl,-ztext   -leclgc
 -ldl  -lm -lsocket -lnsl -lintl  -lgmp

Now the funny thing is that if I copy the *.so file to a Linux box with
"scanelf' (none of the Solaris boxes have this program), I get different
results which I do not know how to interpret. scanelf -qtT is supposed to
reveal the text relocations, but all it shows is function calls and global
variables and they are tagged "optimized out" which I do not know how to
interpret.
