Build errors

[miniskar]

I am getting several compilation errors during the build. I have followed the steps exactly as mentioned in the README.

Any suggestions to resolve these errors?

HI @miniskar, this seems to be a linking error. Could you please post your Conan profile configuration and the system configuration you are using (os, compiler toolchain, etc.) as well as the exact commands you entered to build?

[miniskar]

I tried it using two different profiles.

1. using gcc

[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=11
compiler.libcxx=libstdc++
build_type=Release
[options]
[build_requires]
[env]

2. using clang

[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=clang
compiler.version=17
compiler.libcxx=libstdc++
build_type=Release
[options]
[build_requires]
[env]

Both are reporting same link time errors.

[taalexander]

Hmm, do you think you could post the full Cmakelogs so that I could look in more detail?
