I have checked the flags that you suggest and they are all empty. At least,
when I "echo" them
(echo $LDFLAGS, etc) in the Konsole in which I am running make, empty space
is returned.
I started sage installation from scratch (running first configure and then
make).
I have also seeked anything whose name contains "*pcmpio*" in my /usr
directory and nothing appears.
My main concern is that I cannot find any useful information about pcmpio
in the internet, what is certainly strange.
Where is it supposed that this library should exist? If I had an idea about
this, I could try to find any suitable
library container within the distro or outside it.
Thanks.
