Could anyone explain, why go compiles executable without any issue,
but it fails to run? I'll appreciate any feedback!
If you want to run programs from the build directory you would
normally have to use “./run ...” which sets up environment variables
like LD_LIBRARY_PATH so that it uses the locally built library.
For example:
$ nbdkit memory 1G
$ ./run ./golang/examples/get_size/get_size nbd://localhost
size of nbd://localhost = 1073741824
$ killall nbdkit
