From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922 Description of problem: Linking with shared object fails with message hidden symbol `__dso_handle' in /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/crtbegin.o is referenced by DSO Probably same as bug #109457 Tried to uninstall libaio but rpm said it wasn't installed despite being in /usr/lib Didn't understand patch listed under #109457 I don't need libaio can I remove it or is there a workaround ? Version-Release number of selected component (if applicable): gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-24) How reproducible: Always Steps to Reproduce: 1. I have not yet simplified code because it seems like previous verified severe error. 2. 3. Actual Results: load error Expected Results: expect to produce executable Additional info: On older system with RH Linux 7.1 with gcc 3.2.3 installed the code links and runs. This is problem with system libraries
A colleague of mine, James Quirk, had previously come across this bug and gave me a workaround. I had made shared object using g++ and tried to link shared object into execuatble using g++. I can get this to work if I compile object with 1 line void* __dso_handle; and link it with shared object. Then g++ makes executable without error. I was mistaken that my problem was related to previous bug #109457 But that is only reponse I got from bugzilla querry for dso_handle. google search gives slew of comments related to dso_handle problems. When is this bug going to be fixed ?
Please provide a reproducer.
Created attachment 97695 [details] tar file of simple source to reproduce __dso_handle error tar xvf dso_bug.tar make Main gives 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 Variation make Work; ./Work # runs fine The line that cause ld problem is #include <iostream> in source Hello.C for shared object.
Your testcase is broken. Never ever use ld -shared, always use gcc -shared or g++ -shared, it knows the details how to build correct shared libraries unlike your makefile.
