Detection of libatomic is broken since version 2.47.0 and
b7f0d87daf
because C language is not enabled anymore:
-- Looking for __atomic_fetch_add_4 in atomic
-- Looking for __atomic_fetch_add_4 in atomic - not found
CMake Error at cmake_modules/CheckAtomic.cmake:59 (message):
Host compiler appears to require libatomic, but cannot find it.
Call Stack (most recent call first):
CMakeLists.txt:54 (include)
Indeed if C language is not enabled, the test will be run with the C++
compiler resulting in the following error:

<command-line>: error: new declaration ‘char __atomic_fetch_add_4()’ ambiguates built-in declaration ‘unsigned int __atomic_fetch_add_4(volatile void*, unsigned int, int)’ [-fpermissive]
whereas with a C compiler, we'll get:

i2pd
i2pd (I2P Daemon) is a full-featured C++ implementation of I2P client.
I2P (Invisible Internet Protocol) is a universal anonymous network layer.
All communications over I2P are anonymous and end-to-end encrypted, participants
don't reveal their real IP addresses.
I2P client is a software used for building and using anonymous I2P networks. Such networks are commonly used for anonymous peer-to-peer applications (filesharing, cryptocurrencies) and anonymous client-server applications (websites, instant messengers, chat-servers).
I2P allows people from all around the world to communicate and share information without restrictions.
Features
- Distributed anonymous networking framework
- End-to-end encrypted communications
- Small footprint, simple dependencies, fast performance
- Rich set of APIs for developers of secure applications
Resources
