Now that it is released, I setup a spare machine and installed it. The =
installation went fine. However, all my applications need to be =
recompiled and tested. The first problem I encountered was that ld =
couldn't find the BIO_ symbols. Apparently they have moved to =
libcrypto. I found no notice of that change in UPDATING. Adding =
lcrypto to the ld command fixed that. However, none of the programs =
run. They all build correctly, but immediately exit with an error:
ld-elf.so.1: Undefined symbol "sock" referenced from COPY relocation in =
/usr/local/RSS/src/check_db
These programs all compile and run on 11.0 and 11.1. They are in =
production on 11.1.
There is a project shared library (librss) that has an integer "sock" =
defined at the top level. It is referenced in check_db. Here is a =
reduced version of the code:
rss.c
_____________________
#include rss.h
int sock
void initialize ()
{
sock =3D 3;
}
_____________________
rss.h:
_____________________
extern sock
void initialize ();
_____________________
check_db.c
_____________________
#include rss.h
int main (int argc, char *argv[])
{
initialize ();
}
_____________________
Makefile:
_____________________
rss: rss.c rss.h
$(CC) -fPIC -c -Wall rss.c -I/usr/local/include -L/usr/local/lib =
-lrss=20
$(CC) -shared -W1,-soname,librss.so -o librss.so rss.o=20
check_db: check_db.c
$(CC) -o check_db check_db.c -I/usr/local/include =
-L/usr/local/lib -lrss=20
It is interesting that there are a number of other variables defined =
like sock. It doesn't complain about any others, but perhaps that's the =
first one it encounters. Has something changed with respect to global =
variables? I find no indications of that in UPDATING.
