Listing function exports from object file

DreamWarrior · #1 (**permalink**) 10-17-2007

Is it possible to view all the functions exported by a given object file?

"dump -tv" comes the closest, but what exactly am I looking for to determine whether the symbol exists in the object file?

Essentially, I have a library that requires a call to "xdr_sizeof" and the compile is failing because the linker can not find it. I am curious if I can find where (and if) this function is provided so I can link it in. I have ran the following under /usr/lib:

Code:

for i in `find . -name "*.a"`
do
cnt=`dump -tv $i | grep -c xdr_sizeof`
if [ $cnt -ne 0 ]
then
echo $i " " $cnt
fi
done

Running this I get:

./libnsl.a 3
./libnsl_r.a 3
./libtt.a 1
./libnisdb.a 4

How do I know which of those, if any, actually contains the xdr_sizeof function I want? Is there a better way to do the dump to limit it only to outputing lines for functions exported by the library? Am I completely off base here? I know the function can not be in four different libraries...or it shouldn't be....

AIX 5.2 is the O/S if it matters!

Thanks y'all!
