Some of the configurations under Ubuntu

The exchange of the source under Ubuntu ....

Because their hands cheap, all of a sudden six months of painstaking efforts to destroy all, my entire embedded learning Process code AH, project AH, the problem ah, all lost ... and the evil disposition ...

No way, also reload the system ...

Installed in VMware under the Ubuntu, there are many problems ah, today began to record in the learning process throughout the configuration process ... Safekeeping .....

1, Change Source

In the shell when the command to use the Apt-get command, always prompt: Could not open file '/etc/apt/sources.list ', this is the source was deleted, this is OK, the entire configuration process as follows:;

A, first back up the file:

sudo cp/etc/apt/sources.list/etc/apt/sources.list_backup

B, add Source:

Gedit/etc/apt/sources.list

Copy the source list to the Sources.list file, and then save. Some sources are provided below:

C, UPDATE:

Apt-get Update this process takes a certain amount of time, the only thing we can do is to knock a yes,no, and then just wait .... Patience....

2, the installation of the cross-compilation environment

This is very simple, download the installation package: ARM-LINUX-GCC 4.3.2.tgz

First unpack this installation package,

Tar xvzf ARM-LINUX-GCC 4.3.2.taz-c/(-c/This will automatically extract this file to/usr/locl/this folder)

This command will add an arm folder under/usr/local, enter this folder, and then locate the bin file, note the path at this point, such as the route.

Finally, add the path path to the path:

Edit the/ROOT/.BASHRC file to add a line like this:

Export path= $PATH:p ath

Then save, restart the shell terminal, and then ARM-LINUX-GCC This command can be used ...
