Hi!
I've recently tried to install commoncpp2 from source and I was unable
due to a compilation error. This error has appeared in every version
I've tried so far.
I have attached the error message when compiling commoncpp2-1.8.1 with
gcc v9.3.0.
Steps to reproduce the problem:
- Download commoncpp2-1.8.1.tar.gz
- tar -xvf commoncpp2-1.8.1.tar.gz
- cd commoncpp2-1.8.1
- ./configure
- make
Maybe I am doing something wrong or am missing something?
I am happy for any pointers.
Thank you in advance and Kind Regards
