Hi,
I have installed the CLN library version 1.3.0 and wanted to use it.
however I am not able to compile even the simple fibonacci.cpp example.
I have installed the library with ./configure --prefix=/home/schulz_m
and i tried to use your documentation to set all the compiler flags
appropriately.
the original files after unpacking are under /home/schulz_m/cln-1.3.0
and the fibon.cpp is in my home directory. after typing make test I get
the following error (makefile and cpp, g++ version below):
make test
