Can't compile nmap v4.76

[Stavros]

Ok, I downloaded the linux source and ran ./configure and I get an error:

Code: Select all

configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
configure: error: ./configure failed for libdnet-stripped

What does this mean?

ummm...is g++ (the C++ compiler) installed at all? seems it's not....

[Stavros]

Edit: Reading comprehension....

I swear I need to stop skimming. I installed g++ and it worked.

let me know what distro it is, for Debian style (Debian, Ubuntu, etc.) simply install it via apt-get, best get the C compiler (gcc) too at the same time:

Code: Select all

apt-get install g++ gcc

the error you got simply means /lib/cpp wasn't found, and because cpp is a part of g++ it is a almost safe sign that g++ isn't installed...for some weird reason it isn't part of a default Linux install, at least not of Debian and Ubuntu.

edit: oops, posted at the same time as you, good it worked now, but best get gcc too at this opportunity..
