good news its working in that its hiding symbols.
nm -g --defined-only ./libopendkim/.libs/libopendkim.so | fgrep -v dkim_
(empty)
The bits like 00000000002182e8 d policyflags
from that seem to be there are harmless. I tried the following test.
test.c:
extern int policyflags;
int main(int arc, char **argv)
{
return policyflags+2;
}
correctly fails to link against policyflags:
gcc -o test test.c libopendkim/.libs/libopendkim.so
/tmp/cc4S0pOP.o: In function `main':
test.c:(.text+0xd): undefined reference to `policy_flags'
collect2: ld returned 1 exit status
bad news is the string functions dkim_str* don't link in opendkim (they aren't
in dkim.h):
....
cvs/libar/.libs/libar.so -lssl -lcrypto -pthread
opendkim_stats-opendkim-db.o: In function `dkimf_db_strerror':
/home/dan/software_projects/opendkim-cvs/opendkim/opendkim-db.c:1732:
undefined reference to `dkim_strlcpy'
/home/dan/software_projects/opendkim-cvs/opendkim/opendkim-db.c:1739:
undefined reference to `dkim_strlcpy'
opendkim_stats-opendkim-db.o: In function `dkimf_db_walk':
to add them or not? Not sure here.
As per the patch attached, I think the generation could be handled with a
little less indirection however that's just personal preference.
I checked libar and its fine with exports.
libvbr seems to have more in vbr.h than nm -g --defined-only
./libvbr/.libs/libvbr.so
don't know why - didn't look that hard.
