cgccmakefileredishiredis

Error while loading shared libraries, cannot open shared object file: No such file or directory (hiredis)

I'm in the alpha stages of writing a C program which uses redis on the back end.

I've tried building/installing hiredis (make && sudo make install) and running the test (which pass mostly) but when trying to build the example.c program i get an error that hiredis.h couldn't be found.

Building on the command line with: gcc -v example.c -l hiredis -I /usr/local/include/hiredis/

Things I've tried:

  1. pkg-info hiredis returns 0
  2. uninstall/reinstall via (make && ./hiredis-test && sudo make) and (make clean)
  3. building example.c in the same directory as hiredis.c and hiredis.h (still No Such file or directory)
  4. gcc -v example.c -l hiredis -I /usr/local/include/hiredis/ (And other variations of this)

All with no luck.

I'm guessing I'm not linking the programs correctly for gcc but the documentation doesn't have any build examples.

What am I doing wrong that wont let me build this code (or any code) using hiredis?

the exact output is...

Which produces an a.out. When trying to run that program. I get the following error.

./a.out: error while loading shared libraries: libhiredis.so.0.13: cannot open shared object file: No such file or directory
Solution

  • The problem was the libhiredis wasn't in the ldconfig path. While the build process was correct and it copied everything to the correct directory ldconfig did not know about its location.

    You can use ldconfig -p to see all library ldconfig currently know about.

    You can add the path to ldconfig with

    sudo echo "/usr/local/lib" > /etc/ld.so.conf.d/local.conf

    &

    sudo ldconfig
