I have a library that was compiled on an unknown Ubuntu machine, And I'd like to determine what version of Ubuntu that machine had at the compile time. My idea was to try and find the versions of different libraries used (e.g. the kernel), knowing that these versions changed with different releases. Iv'e tried using nm and ldd, but I can't seem to find any relevant info.Any suggestions?
Finding the library versions a library was linked against

Maybe readelf -a It displays information about ELF files. If the object you are studying still contains the comment section, you may try to extract it by readelf -p .comment yourfileFor example$ cat test.cint main () {  return 0;}$ gcc test.c$ readelf -p .comment a.outString dump of section '.comment':  [     0]  GCC: (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1objdump could provide the same information.If the comment section is stripped, you may try to read the GCC runtime symbol version info from the  readelf -a command if it is a c++ compiled library. (Note, that is the version of symbols supplied to the compiler and not necessarily the version of the compiler.) I don't know how usefull that would be to track down the Ubuntu version.
