Building E stl-0.8.9t
on Windows

Installing a Development Environment

We recommend:


See the Dependencies section for information on obtaining appropriate versions of a JDK, the Cygwin environment, the BYacc/J parser generator, and the zipping tools.

The E Source Distribution

For Windows users, we recommend downloading the zip of E source distribution.

Compilation Notes

There are still some deprecated methods used in this release. You can safely ignore these warnings for now.

Building from Makefiles

To build the release, cd to the e/src directory and type make. Be sure that "cygwin/bin" is on your PATH ahead of Windows directories, like "C:/WINDOWS/COMMAND". In particular, some have had problems finding the wrong "make.exe" and "find.exe". Be sure the version of both of these found on your PATH are the ones in "cygwin/bin".

Building in a Java IDE

E itself is a pure Java program. If you don't need to rebuild the installation tools, you can happily develop E using a Java-only development environment, such as Symantec's Visual Cafe (>= 4.1 Standard Edition). For concreteness, and because it's what I use, I'll explain how to build a Cafe project for E, but users of other development environments should easily see how to do likewise in their system. The following instructions assume that you unpack your sources into "d:/e/src", and that you install into "c:/Program Files/".

To start with, create a "New Project". For a project type, select "Empty Project" since we don't want it generating new source files for us. Select "Project Options". Under the "Project" tab, deselect "Enable RAD for New Files" since this is needless overhead for us. The "Project Type" should be "Application - A program that requires a java.exe to run".

For the "Main Class" enter "org.erights.e.elang.interp.Interp" -- the class whose main() is the top of the E interpreter. Your command line arguments string should be

"-De.home=c:/Program Files/" "d:/e/src/esrc/scripts/elmer.e"

Elmer is a good way to test each new build of E.

On the "Compiler" tab, we recommend deselecting "Show command line", but salt to taste.

On the "Directories" tab, for "Show directories for", first select "Input class files". This is where you enter the equivalent of the CLASSPATH. You should enter the following in this order:

...these directories for these reasons
For the *.emaker files
Where compiled java goes
The Hydro library of capability-oriented collection classes, from
Where binary resources, such as icons, are found.


For "Output files", "Output directory", enter "d:\e\classes". This is where Cafe's compiler will place the *.class files.

Now we need to suck all the e\src\jsrc\*.java files into the project. Right click in the Project pane and select "Insert files". Navigate to the directory "e\src\jsrc", select "subfolders", click on "Add All", and then click on "Ok". Wait while it adds all these files to your project. Once it's done, be sure to remember to save your project or Save All.

Finally, on the "Project" menu, select "Run in Debugger". Hopefully, after everything successfully compiles, you'll see an Elmer window. You are now running Elmer under the Cafe debugger. Have fun!
