I’m trying to run a C program, but every time I try to run it I get this message:

error while loading shared libraries: libpcap.so.0.8: cannot open shared object file: No such file or directory

I've re-installed libpcap; I've installed gcc and g++; I’ve updated it and I’m lost. I’m not sure what else I can do. Could anyone help out?

  • What is the output of sudo yum provides '*/libpcap.so*' ? – Red Cricket Feb 28 '15 at 1:24
  • pastebin.com/iXSWYcrg is the output – Adam Feb 28 '15 at 2:07

    Looks like you have the libs for libpcap-1.4. Do you have the source for your c program? Looks like you will need to recompile and link it. – Red Cricket Feb 28 '15 at 3:31

It appears that compiling this:

gcc -o example example.c -l:libpcap.so.1.7.4

still requires that

libpcap.so.0.8

be on your system.

And I have no idea why. However, making a link from (whatever version you're using, notice I'm EXPLICITLY telling it to link to libpcap.so.1.7.4) whatever version you do have to libpcap.so.0.8 - it will work.
