basic installation trouble

Hi all.

Im having trouble installing asterisk and i could use a little help..well ok, a lot of help, but ill start off simple.

Following the install guide at asterisk guru...

Quote:

Compiling Asterisk on most Linux distributions Accomplish this by opening the folder in which the source codes were extracted (if you are using tarball files), or go to the /usr/src/asterisk folder (if using CVS server) to get the required packages. To go to this directory, see example: #cd /usr/src/asterisk Once here, the final step is to compile: Important: Follow this installation order: libpri, zaptel, asterisk -Installing libpri #cd /usr/src/asterisk/libpri #make clean #make #make install

..i run into this error and im not sure what it means or what to do. Thanks for any and all help.

I suspect you have not got all the relevant dependent libraries installed. Check for:
gcc, glibc-kernheaders, cpp, binutils, glibc-headers, glibc-devel, bison and open ssl.

Also remember you must install as a root user

im not sure how to check whether i have them or not. this is a basic question im sure, but lets say i know i have a file somewhere but im not sure what path its on. what command can i use to get path info? for example lets say i downloaded libpri-1.x.x into /usr/src/asterisk but didnt know thats where it was. how can find out the path i need from my home path?

im using ubuntu gutsy.

thanks again.

To answer my own question;

to find a file, one good way is

find / -name whateverimlookingfor

or

whereis whateverimlookingfor

Those seem to work pretty good
