I am trying to install gretl cvs on the linux distribution "elementary
os" (has an ubuntu-base). Unfortunately, I obtain an error when running
the "make" (not yet "sudo make install") command. I attached a
which I don't understand.
The full compilation command I used within the "/cvs/gretl" folder is
./configure --prefix=/opt --enable-openmp --enable-build-doc && make
Does anybody have a clue what's the error here?
