Description Rob Kirkbride 2003-09-09 10:32:20 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624

Description of problem:
If I create a simple shared object and then attempt to link with this I get :
/usr/bin/ld: main: hidden symbol `__dso_handle' in
/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/crtbegin.o is referenced by DSO

gcc -c -fPIC libtest.cpp (simple class with just constructor)
ld -shared -soname libtest.so.1 -o libtest.so.1.0 -lc libtest.o
/sbin/ldconfig -v -n .
ln -s libtest.so.1.0 libtest.so
g++ -o main main.cpp -L. -ltest

produces the error above.

main.cpp is just :-
#include "libtest.h"

int main() {
  libtest mylib;

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. See description above


Actual Results:  Give the following error 
/usr/bin/ld: main: hidden symbol `__dso_handle' in
/usr/lib/gcc-lib/i386-redhat-linux/3.2.3/crtbegin.o is referenced by DSO

Expected Results:  No errors and the main excecutable should have been produced.

Additional info:

No special information. Reproduced on two different machines.

Comment 1 Jakub Jelinek 2003-09-09 10:47:39 EDT
The bug is in the way you're linking the shared library.
Never ever invoke ld by hand unless you know exactly what consequences it has.
gcc/g++ driver knows better what is needed.
The shared library should have been linked with:
g++ -shared -Wl,-soname,libtest.so.1 -o libtest.so.1.0 libtest.o
