Hi,
I have seen this error for the first time and there are less references in web.
can some one please point me out what causing this error.
Quote:
/home/Prgs/a.out: relocation error:
/home/Prgs/a.out: symbol printf, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference
through GBD when i checked it is generated when the program encountred a printf statement .
But the same code(code having printf statements)was working perfectly some time back.
What changed since it worked? The printf() function is part of libc, so either you installed a new/different version of libc, or you changed something in your program or how you build/link it. Basically, you aren't providing enough information.
I really dont know what i have changed, but after inserting some printf statements here and there for debugging (just to check all printfs are causing the problem or just one.) the problem is solved just like that.
But the problem is not known.
Thanks RubberMan for your response.
This sort of symptom is usually due to some sort of memory error, such as using an invalid pointer or writing beyond the object a pointer refers to, thus causing corruption to parts of the program that may have been related to your issue - the results can be totally random, and will change as you add/remove code (such as printf statements) in the function(s) that caused the problem. You should use a tool such as valgrind in order to find where the memory corruption may be occurring.
As a software developer, never let an issue like this go without understanding exactly what was happening, and what the proximate cause was, otherwise some minor fix is going to cause the issue to reappear at a later time.
