Description Ben Longbons 2012-07-27 00:40:17 UTC 
With recent glibc, every time gdb starts a program, the following is printed:
warning: Could not load shared library symbols for linux-vdso.so.1.
Do you need "set solib-search-path" or "set sysroot"?

A patch for gdb is available here:
http://sourceware.org/ml/gdb-patches/2011-08/msg00331.html
I have tested this with gdb-7.4.1 on amd64, with a native amd64 program,
with glibc-2.15-r2

Note that this won't be fixed in glibc:

Reproducible: Always

Steps to Reproduce:
gdb -ex run true

gdb-7.5 will be out shortly, and this isn't really a regression, so i'm inclined to just wait for that

gdb-7.5 is in the tree now, so this should be sorted
Comment 5 Raymond Jennings 2012-08-18 16:05:57 UTC 
Nope, still broken.

I just merged 7.5, and it's showing the same error with linux-gate.so.1 as before.

Should I open a new bug or should this one be remarked as in progress?
Comment 6 Mart Raudsepp gentoo-dev 2012-08-18 19:07:25 UTC 
Reopening for consideration
Comment 7 Toralf Förster gentoo-dev 2014-08-01 19:49:31 UTC 
Hhm, still a problem here :
