The real compatibility with RHEL <=7.2 (and <=6.8) gdbserver did not make it to DTS-4.1 (see Bug 1324606 for its DTS-5.0 clone). Keeping this Bug at least for a warning suggesting to use more recent gdbserver. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2016:1144 |
Description of problem: gdb>=7.10 (>=DTS-4.0) can no longer access shared libraries via sysroot "remote:" with gdbserver<=7.9. RHEL-7 has gdbserver-7.6.1. Installing DTS-4.0+ gdbserver workarounds that. Version-Release number of selected component (if applicable): devtoolset-4-gdb-7.11-57.el7 How reproducible: Always. Steps to Reproduce: host1$ gdbserver-7.9 :1234 /root/inferior ^^^ host2$ gdb-7.10 -ex 'set sysroot remote:' -ex 'file /root/inferior-copy-from-host1' -ex 'target remote host1:1234' Actual results: warning: "remote:" is deprecated, use "target:" instead. warning: sysroot set to "target:". Reading symbols from /root/inferior-copy-from-host1...done. Remote debugging using host1:1234 Reading /lib64/ld-linux-x86-64.so.2 from remote target... warning: File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead. warning: Unable to find dynamic linker breakpoint function. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ GDB will be unable to debug shared library initializers and track explicitly loaded dynamic code. 0x00007ffff7ddc430 in ??
