Windows Tool Chain Introduction

Introduction

UC-7420/7410’s Windows Tool Chain is a cross development environment that simulates the Linux root file system, allowing users to develop applications in a Windows environment. Install the Windows tool chain to set up a Linux-like environment on your Windows machine. The following figure shows an example of what the Windows Tool Chain environment looks like.

/

Your group is currently “mkpasswd”. This indicates that

The /etc/passwd (and possibly /etc/group) files should be rebuil See the man pages for mkpasswd and mkgroup then, for example, ru mkpasswd –l [-d] > /etc/passwd

mkpasswd –l [-d] > /etc/group

Note that the –d switch is necessary for domain users.

Your Windows OS you use must satisfy the following requirements.

1.Operating System: Windows 2000 workstation or Windows XP professional.

2.Minimum of 500 MB of free hard drive space to install the tool chain and develop programs. All of the disk space must be on a single drive.

3.CD-ROM or equivalent.

4.Ethernet connect to download the application program to UC-7420/7410.

5.Be able to log in as administrator.

6.Use a Windows username without spaces.

You will be using a BASH shell window to enter commands. In addition, for editing text files, such as configuration files, you should use vi editor. Do NOT use WordPad, which could cause problems when the files are transferred to a bona fide Linux environment.
