http://bugme.osdl.org/show_bug.cgi?id=702
Summary: EXPORT_SYMBOL and depmod don't work well together with GCC 3.2.2 Kernel Version: 2.5.67 Status: NEW Severity: low Owner: bugme-janitors@lists.osdl.org Submitter: gmmapowell@yahoo.com
Distribution: Redhat, modified Hardware Environment: i386 Software Environment: GCC 3.2.2, modutils 2.4.25 Problem Description:
Disclaimer: as noted above, I'm using gcc 3.2.2, which isn't the top recommendation, and I think that's the immediate cause of the problem, but I think nevertheless GCC 3.2.2 has it right, and we're currently relying on a bug.
When I build modules and pass them to depmod, it gives me a bevy of unresolved symbols which are found in other modules. When I do an nm on them, I get something like the following:
00000028 ? __ksymtab_NS8390_init 00000008 ? __ksymtab_ei_close 00000010 ? __ksymtab_ei_interrupt 00000000 ? __ksymtab_ei_open 00000018 ? __ksymtab_ei_tx_timeout 00000020 ? __ksymtab_ethdev_init
When depmod comes across these, it does not accept them because of the line
if (objsym->secidx == ksymtab && ELFW(ST_BIND)(objsym->info) == STB_GLOBAL)
and these symbols _aren't_ global because in the header file linux/module.h they are defined as static.
