Commit dedbc69022ba0beaf259463ac8082c86776f7e88 was incomplete resuling
in the following build failure since the addition of the package in
commit 6a0f7c39bcb48fc13aa2ce3fc4996baf1be66483:
-- Check for working CXX compiler: /usr/bin/c++ - broken
CMake Error at /home/autobuild/autobuild/instance-15/output-1/per-package/fluent-bit/host/share/cmake-3.22/Modules/CMakeTestCXXCompiler.cmake:62 (message):
The C++ compiler
"/usr/bin/c++"
is not able to compile a simple test program.
It fails with the following output:
