How to enable old transitive DSO link behaviour?
Looking at Understannding DSO Link Change I understand that (by default) the linker (ld) does not transitively resolves shared library dependencies.
For example for a simple program that calls a function from boost_filesystem and you link like this:
$ g++ boost_remove.cc -lboost_filesystem
Then you get something like:
/usr/bin/ld: /tmp/ccxkAkLn.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'
/usr/bin/ld: note: '_ZN5boost6system15system_categoryEv' is defined in DSO /lib64/libboost_system.so.1.53.0 so try adding it to the linker command line
/lib64/libboost_system.so.1.53.0: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
Sure enough this works:
$ g++ boost_remove.cc -lboost_system -lboost_filesystem
Is there a way to get the old behaviour on Fedora?
(the old behaviour where the linker automatically (i.e. transitively) resolves all shared library dependencies such that just specifying -lboost_filesystem is perfectly fine)
example source:
#include <boost/filesystem.hpp>
#include <string>
using namespace std;
int main(int argc, char **argv)
{
string filename(argv[1]);
boost::filesystem::remove(filename);
return 0;
}
