Positioning of CRT *. O during Emacs installation in ubuntu12.04

I can't wait to install ubutnu12.04 in my new brain.
Later, I wanted to learn how to use Emacs. The result was loaded for two days. A few days ago, due to a problem with the G ++ compiler, it seems that the GCC compiler of this version does not have the G ++ function installed. Later, I added some sources and found some miscellaneous commands on the Internet, I forgot what the command is. It means that sudo apt-Get install build-essential is successfully executed.
It is not expected to be executed. /configure -- prefix =/usr/local/emacs23 -- enable-font-backend -- With-xft -- With-FreeType -- With-X-Toolkit = GTK and continue to report an error, no CRT is found *. o file, let you use the -- with-CRT-Dir command. I checked the configure source code, and it looks like we want you to solve it using -- With-CRT-Dir =... (PATH.

The procedure is as follows:
Create a soft link for CRT *. o
During Emacs installation,/usr/lib/CRT * is required *. O content, but not all CTR *. O is located in the/usr/lib/directory, so you need to create other CRT * in/usr/lib *. O soft link.
Use

Locate crt1.o

Command to locate the location of the crt1.o file. My files are located in the/usr/lib/i386-linux-gnu/directory listing all CRT *. O files
Ll/usr/lib/i386-linux-gnu/* CRT *. o
Create a soft link that uses the ln command to create these files to/usr/lib/, for example:

Ln-S/usr/lib/i386-linux-gnu/crt1.o/usr/lib/crt1.o

Note that here is i386, and some of the above content is found on the Internet, so it is not very similar to my computer. It means it anyway. I use x86_64 to find the path myself.

Yes... However, the installation path is in/usr/local/emacs23 as described earlier.
The Emacs cannot be started directly.
So add your installation path
The default installation path of emacs23 is/usr/local, which is split into several blocks, which are stored in the following directories:
/Usr/local/bin
/Usr/local/share/Emacs/version/LISP
/Usr/local/share/Emacs/version/etc
/Usr/local/libexec/Emacs/version/configuration-name
/Usr/local/info
/Usr/local/man/Man1
If you want to install it in a directory, use -- prefix =/yourpath in configure, but do some link in/usr/local/bin.
So far, emacs cannot be started when you directly enter Emacs in the terminal because/usr/local/emacs23/bin is not in the PATH variable.
CD/usr/local/bin
Ln-S/usr/local/emacs23/bin/*./(create a symbol link)
Enter Emacs in the terminal to start Emacs.

Oh, oh, oh, great!

Oh, my God. It's. Go to bed now! The first time I spoke under the Ubuntu interface. I don't care much about it. Welcome to the bricks.
