protoc: error while loading shared libraries: libprotobuf.so.0: cannot open shared object file: No such file or directory

[一首诗]

After I have installed protoc, I tried this command:

sudo protoc -I=~/test/pb2/src/pb/ --python_out=~/test/pb2/src/python/
addressbook.proto

BUT what I got is:

protoc: error while loading shared libraries: libprotobuf.so.0: cannot
open shared object file: No such file or directory

The library is where it should be

libprotobuf.so: /usr/local/lib/libprotobuf.so.0 /usr/local/lib/
libprotobuf.so

What's the problem?

You most likely do not have /usr/local/lib in your dynamic loader's library path.

Oh, I checked my "etc/ld.so.conf.d/libc.conf"

There is

"/usr/local/lib"

--------------------

I've ran "make test" and everything seems OK.

OK, I figured it out, you have to set environment varialbe:

export LD_LIBRARY_PATH=/usr/local/lib

I'm using ubuntu server edition. Hope this could help others :)

I'm kind of surprised to hear this issue reported so much.  Is the protobuf package somehow different from all the other autoconf-based library packages out there?  Or is it just that people rarely install libraries from source packages, preferring apt-get instead?

In any case, I guess the readme should really suggest using --prefix=/usr.

Also, why the heck do linux distros not include /usr/local/lib in the library path automatically, given that the every autoconf package installs there by default?

I've installed some applications from source code on ubuntu, that's
not that easy.

Maybe Ubuntu is not so compatible with other distros

But apt-get do save a lot of time, when what you want to install
depends on many other packages.

After `sudo ldconfig /usr/local/lib` I no see this problem again
