This bug is appearing while linking opie libraries. I have a self contained
test.
The error message is
launcher.o: In function `Launcher::properties(AppLnk*)':
launcher.cpp:(.text+0x21c8): undefined reference to
`LnkProperties::~LnkProperties()'
the fist link generate a shared library which contains HIDDEN for visibility
for this symbol with out the fix for PR #9679 this works fine because visibility
is default.
The problem is happening after the fix for PR #9679 was committed.
Particularly
/* Skip weak definitions of symbols that are already defined. */
if (newdef && olddef && newweak)
- *skip = TRUE;
+ {
+ *skip = TRUE;
+
+ /* Merge st_other. If the symbol already has a dynamic index,
+ but visibility says it should not be visible, turn it into a
+ local symbol. */
+ elf_merge_st_other (abfd, h, sym, newdef, newdyn);
+ if (h->dynindx != -1)
+ switch (ELF_ST_VISIBILITY (h->other))
+ {
+ case STV_INTERNAL:
+ case STV_HIDDEN:
+ (*bed->elf_backend_hide_symbol) (info, h, TRUE);
+ break;
+ }
+ }
is causing the link to fail.
