App execution fails, can't find glib/libstdc++

hi ya’ll,
im using the last of version(0.8.4). the app is being started automatically every morning for the last 3 months and just recently it started to fail

/usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20’ not found (required by /path/to/app)

after simply recompiling the app it’s working again, without the problem, though it keeps happening after a while again(next day or so). do you have any idea what this could be related to? maybe it’s not even something with of, but maybe you have a pointer to some info that might solve it…

thanks already,
marcel

PS: here’s some info about the system

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

returns

GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
GLIBCXX_3.4.7

GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.11
GLIBCXX_3.4.12
GLIBCXX_3.4.13
GLIBCXX_3.4.14
GLIBCXX_3.4.15
GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19
GLIBCXX_DEBUG_MESSAGE_LENGTH

These two packages are installed

libstdc+±4.8-dev:amd64
libstdc++6:amd64

gcc/g++ 4.8.4 is installed.

I really have this problem here:

It looks like you have different versions of g++ installed, and maybe your program can not find the 3.4.0?
I would probably run update-alternatives --config gcc to be sure to run the g++ version required by your program.
This link maybe useful to you:

The last version of OF is 0.9 :wink:

I only have one version installed, that’s the thing, no alternatives present. I’m trying to avoid upgrading gcc, it should not be a dependency to have 4.9 installed.
