STL Container Support

Reference:
https://sourceware.org/gdb/wiki/STLSupport

Change directory (cd) to the directory you want the scripts to live in

svn co svn://gcc.gnu.org/svn/gcc/trunk/libstdc++-v3/python

If you are behind a firewall, then you may need to edit the ~/.subversion/server file under [global] and uncomment all of the http-* commands and give them the correct info for your proxy. You should then change the svn:// to http://

Then edit the ~/.gdbinit file and add the following:

python
import sys
sys.path.insert(0, '/home/me/gdb_printers/python')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

(off-topic) Setting up Plex on CentOS 6.5 for Home Network

Download and run Plex



If http://localhost:32400/web returns "404 Not Found", then:


$ sudo vi /etc/sysconfig/selinux

change SELINUX=enforcing to SELINUX=disabled
reboot

go to plex url (localhost:32400/web) and it will load

$ sudo vi /etc/sysconfig/selinux

change SELINUX=disabled to SELINUX=enforcing
reboot


If http://192.168.1.2:32400/web doesn't work from other machines, then open port:

$ gvim /etc/sysconfig/iptables

add:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 32400 -j ACCEPT

$ sudo service iptables restart

To check if the port is being used:

$ lsof -i :32400
OR
$ netstat -an | grep 32400 | grep LISTEN

To add network sources, mount the source, then add it:

$ sudo mkdir /mnt/nas1

$ sudo mount -t cifs //192.168.1.3/videos/ /mnt/nas1 -o username=user,password=123123

If this works for you, then you need to set these points to mount at boot:

$ sudo gvim /etc/fstab

Add:

//192.168.1.3/videos/  /mnt/nas1               cifs    defaults        0 0
//192.168.1.4/videos/  /mnt/nas2               cifs    defaults        0 0

Vim auto (IntelliSense like) completion using GCCSense & gcc-code-assit

Download and Instructions from:
http://cx4a.org/software/gccsense/

Prerequisites:
http://gcc.gnu.org/install/prerequisites.html

Remember to setup your build environment, GCC, GMP, etc. (PATH, LD_LIBRARY_PATH, etc.)

wget http://cx4a.org/pub/gccsense/gcc-code-assist-0.1-4.4.4.tar.bz2
tar xvf gcc-code-assist-0.1-4.4.4.tar.bz2

cd gcc-code-assist-0.1-4.4.4/

./configure --prefix ~/gcc-code-assist-0.1-4.4.4_install --program-suffix=-code-assist --enable-languages=c,c++ --disable-bootstrap --disable-multilib

Received error:

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.2+.

Try the --with-gmp and/or --with-mpfr options to specify their locations.

Copies of these libraries' source code can be found at their respective

hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.

See also http://gcc.gnu.org/install/prerequisites.html for additional info.

If you obtained GMP and/or MPFR from a vendor distribution package, make

sure that you have installed both the libraries and the header files.

They may be located in separate packages.

Install MPFR to fix error @ http://www.mpfr.org/mpfr-current/#download :

wget http://www.mpfr.org/mpfr-current/mpfr-3.1.2.tar.gz

tar xzf mpfr-3.1.2.tar.gz

cd mpfr-3.1.2

./configure --prefix=~/mpfr-3.1.2_install

Installing vim (must be 7.3.584 w/ python2 support):

If you have root:

https://github.com/Valloric/YouCompleteMe/wiki/Building-Vim-from-source

If you don't have root:

http://www.vim.org/sources.php
Copy the version you want, extract and cd into it
