Compilando o PJPROJECT "PJSIP"

Install pjproject

Next you will download and install the pjproject sip library directly from pjsip.org. But first we’ll change directories to work in the /usr/src directory.

# cd /usr/src
# wget http://www.pjsip.org/release/2.3/pjproject-2.3.tar.bz2
# tar -jxvf pjproject-2.3.tar.bz2
This will create the pjproject-2.3 directory. Change to this directory and run the following set of commands to build and install the pjproject sip library.

# cd pjproject-2.3
# ./configure CFLAGS="-DNDEBUG -DPJ_HAS_IPV6=1" --prefix=/usr --libdir=/usr/lib64 --enable-shared --disable-video --disable-sound --disable-opencore-amr
This command must be modified when using a 32-bit operating system. Just remove the --libdir=/usr/lib64 option from the command. The other options may be different depending on how you want to use Asterisk. More information about these options can be found on the Asterisk wiki or by running the command ./configure --help. The next four commands will build, install and link the pjsip libraries.

# make dep
# make
# make install
# ldconfig
And finally this next command will verify the pjsip libraries have been dynamically linked.

# ldconfig -p | grep pj
