Install and Use

Building and Installing

Assuming you meet the basic build requirements (please refer to the README.md file), building and installing in an UNIX environment should be as easy as follows:

$ make
$ sudo make install

By default the make install command attempts to install the compiler in /opt/lpc/. You can change the install directory by changing the variable INSTALL_DIR in the Makefile.

Important: after installing, make sure to export the environment variable LPC_HOME and give it the same value that what INSTALL_DIR contained at the moment of install.

Important note for MS Windows users: currently, we only support building the compiler using a Cygwin environment. Visual Studio should work, provided a minor change is performed on the source files generated by GNU Bison.

Invoking the Compiler

To invoke the compiler to build a sample L+ source code file, use the following command:

$ $LPC_HOME/bin/compiler.sh program.lp

On MS Windows, use the following command:

%LPC_HOME%\bin\compiler.bat program.lp

In both cases, remember to set the LPC_HOME environment variable pointing to the L+ compiler root directory before invoking the compiler script.
