Epilogue

I’ve just uploaded a new version of Epic to hackage, so installing it should now be a matter of typing:

cabal install epic.

You will also need the Boehm garbage collector, available from here. If you’re on a Mac, installing it should require nothing more than:

port install boehmgc

Also, if you’re on a Mac, you will probably have to persuade gcc to look in the right place for the relevant libraries. I have the following lines in my .profile which do the trick:

export C_INCLUDE_PATH=/opt/local/include:$C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH=/opt/local/include:$CPLUS_INCLUDE_PATH
export LD_LIBRARY_PATH=/opt/local/lib:$LD_LIBRARY_PATH
export LIBRARY_PATH=/opt/local/lib:$LIBRARY_PATH

To check if everything has worked, put the following text into a file called hello.e:

main () -> Unit =
   foreign Unit "putStr" ("Hello world!\n":String)

Then execute epic hello.e -o hello, and you should have an executable hello world program.
