## Setting Environment for x86 Compiler

You can build files and projects using the Carbide.c++ command-line tools.

The command-line tools are located in the plugins\x86Build folder and include:

- \env_switch - contains the env_update.exe program which installs the environment variables used by the command-line tools. You must run the env_update.exe program before any of the command-line tools can operate. It is not required to run if building from Carbide.
- \Symbian_Support - contains the libraries, headers, and other support files necessary to use the command-line toosl
- \Symbian_Tools - contains the command-line tools compile (mwccsym2.exe), assembler (mwc++filt.exe), and linker (mwldsym2.exe) project files

#### Running a Command-Line Tool

1. Locate and launch env_update.exe to install the environment variables required by the command-line tools

Follow the onscreen instructions to install the correct environment variables.

2. In the Command Prompt window, enter the tool name and options to invoke the command-line tool
