I'm seeing a weird problem, and any help would be appreciated.
The summary is I create an executable which preloads a library, but there is no
lt_preloaded_symbols generated.
First, libtool is invoked to build libsidcpu.la from object files:
/bin/sh ./libtool --mode=link g++ -all-static -o libsidcpu.la -rpath
/scratch2/tmorita/sid/ubicom-distro/toolchain-src/install/lib/sidlib -module
-no-undefined simwcpu.lo cfgroot_interface.lo ubicom32/libsidubicom32.la
-L../../../libiberty -liberty -lm
rm -fr .libs/libsidcpu.a .libs/libsidcpu.la .libs/libsidcpu.lai
.libs/libsidcpu.so .libs/libsidcpu.so.0 .libs/libsidcpu.so.0.0.0
rm -fr .libs/libsidcpu.lax
mkdir .libs/libsidcpu.lax
rm -fr .libs/libsidcpu.lax/libsidubicom32.a
mkdir .libs/libsidcpu.lax/libsidubicom32.a
(cd .libs/libsidcpu.lax/libsidubicom32.a && ar x
/scratch2/tmorita/sid/ubicom-distro/toolchain-src/build/ubicom32-elf/sid/main/sidlib/ubicom32/.libs/libsidubicom32.a)
ar rc .libs/libsidcpu.a simwcpu.o cfgroot_interface.o
.libs/libsidcpu.lax/libsidubicom32.a/ubicom32mainplustimer.o
.libs/libsidcpu.lax/libsidubicom32.a/ubicom32cpu.o
ranlib .libs/libsidcpu.a
rm -fr .libs/libsidcpu.lax
creating libsidcpu.la
(cd .libs && rm -f libsidcpu.la && ln -s ../libsidcpu.la libsidcpu.la)
Next, libtool is invoked to build libsid.la which -dlpreopens libsidcpu.la:
/bin/sh ./libtool --mode=link g++ -all-static -o libsid.la -rpath
/scratch2/tmorita/sid/ubicom-distro/toolchain-src/install/lib/sidlib
-export-dynamic -static -export-symbols-regex '[a-zA-Z0-9]*_library$'

ar rc .libs/libsid.a sidlib.o
ranlib .libs/libsid.a
creating libsid.la
(cd .libs && rm -f libsid.la && ln -s ../libsid.la libsid.la)
Finally, libtool is used to build simrefcompare, but there is no
lt_preloaded_symbols generated:
(It's using libtool-1.5.18 because I was trying different versions of libtool
to attempt to resolve the problem)

Is there an obvious reason why lt_preloaded_symbols is not generated even
though -dlpreopen is specified?
