C++ library SONAME without full version number

[anandvsr]

Describe the issue

In onnxruntime native so file, the SONAME is with version name.

why don't we maintain library version as like

libonnxruntime.so        # is called the linker-name used for linking.
libonnxruntime.so.1      # is called the soname used by the operating system loader.
libonnxruntime.so.1.18.1    # is called the real-name which is updated by the library maintainer.

It required a scenario where I build a library/executable, which is used to compile with certain version, say v1.17.3. It become the user of the library/executable also must stay with v1.17.3 I they update the library to 1.18.1 it couldn't find the library libonnxruntime.so.1.17.3.

To reproduce

Download a native library tarball v1.17.3.

Create a simple cpp file with create a empty session.

// sample.cc
#include <onnxruntime_cxx_api.h>
#include <iostream>

int main(){
  Ort::Session session(nullptr);
  std::cout << "Session created successfully!\n";
  return 0;
}

compile it using g++

g++ -o sample sample.cc \
    -Ionnxruntime-linux-x64-1.17.3/include \
    -Lonnxruntime-linux-x64-1.17.3/lib \
    -lonnxruntime

Use LD_LIBRARY_PATH to add the library in search path

LD_LIBRARY_PATH=onnxruntime-linux-x64-1.17.3/lib ./sample

Got output

Session created successfully!

If I run it with v1.18.1 in LD_LIBRARY_PATH, it doesn't work.
Download a tarball v1.18.1

LD_LIBRARY_PATH=onnxruntime-linux-x64-1.18.1/lib ./sample

Got error like

./sample: error while loading shared libraries: libonnxruntime.so.1.17.3: cannot open shared object file: No such file or directory

$ readelf -d libonnxruntime.so | grep SONAME
 0x000000000000000e (SONAME)             Library soname: [libonnxruntime.so.1.19.0]

I will change it.
