When you make, pipe your output through c++filt:

g++ main.cpp -o main -lcryptopp 2>&1 | c++filt

Then post the error message.

I've got a feeling you are mixing and matching header files. Maybe the
you are using upcoming Crypto++ 6.0 header files and a Crypto++ 5.6.3
library from Fedora. That's because of:

 undefined reference to
CryptoPP::BufferedTransformation::Skip(unsigned long)

The 'unsigned long'  is _now_ the word64 type, but that change
occurred at Crypto++ 5.6.5. At 5.6.4 and below a word64 was 'unsigned
long long'. At Crypto++ 5.6.5 it was changed to a 'unsigned long'
under LP64 data models.

You should not be missing a "BufferedTransformation::Skip(unsigned
long)". If you are missing anything, it should be
"BufferedTransformation::Skip(unsigned long long)".

The change is detailed under "Notes for Distros" at
https://www.cryptopp.com/release565.html .

Still the same. I tried to uninstall *cryptopp* and *cryptopp-devel* 
packages, then do *dnf clean all*, then install the packages back and still 
the same error. The problem is somewhere in this line:
CryptoPP::FileSource createFileFingerprint(filePath.c_str(), true, new 
CryptoPP::HashFilter(sha256Hasher, new CryptoPP::HexEncoder(new CryptoPP::
StringSink(fileFingerprint;

Everything works fine only if I delete the line above and keep only the 
hasher init:
CryptoPP::SHA256 sha256Hasher;

What you mean by "entire build process"? I have installed CryptoPP from 
Fedora repos (5.6.3), then for build I do *g++ main.cpp -o main -std=c++17 
-lcryptopp*. Nothing more. I don't use CMake and Make for this program yet. 
The error I get is pasted on Pastebin. 

Also, I want apology for my English, since I'm not native. I'll try my best 
for you, to understand me.

You have not provided enough information.

Please provide the entire build process for your program and the
library. Be sure it includes your call to make, the compile commands
used to compile source files, the link command used to link objects
and libraries, and the error messages.

When the compile command completes by showing  nothing, that means it 
succeeded.

Your next step is to run it with ./main

OK, now that's strange. What version of Crypto++ is this? Are you building
it yourself or are you using a system package?

Show the entire build process for your program. Be sure it includes your
