That did it! Thank you very much, Gabriel -- my beta-tester is able to
install my software package, without having to install the Findlib module.
To summarize, this is what I had to do -- and please correct me if I am
mistaken somewhere: First, I compiled CIL and my modules into a directory,
with commands (in a Makefile) similar to the following:
$ mkdir mylib
$ export MYLIBDIR=$PWD/mylib
$ cd cil
$ ./configure && make
$ make install-findlib OCAMLFIND_DESTDIR=$MYLIBDIR
$ cd ../myModule
$ OCAMLPATH=$MYLIBDIR ocamlbuild -use-ocamlfind -package cil myModule.cma
myModule.cmxs
$ OCAMLFIND_DESTDIR=$MYLIBDIR ocamlfind install myModule META
_build/myModule.cma _build/myModule.cmxs
As far as I can tell, these commands compile CIL and dump the compiled
files into a directory (here, 'mylib'). Then, these commands also build and
compile my own module (here, 'myModule.ml' located in a folder called
'myModule') and dump the compiled files into the same directory, installing
it (somehow) into CIL.
Now, to run my installed module, I used the following command:
$ OCAMLFIND_CONF=... OCAMLPATH=$MYLIBDIR
CIL_FEATURES=cil.default-features,myModule
cil/bin/cilly.byte --help
where OCAMLFIND_CONF is set to the path of the minimal configuration file
that contains the following:
path = ""
destdir = ""
I use this format since my code determines the value for OCAMLPATH
dynamically.
(Sidenote: Since the interaction with the Cilly driver is done mostly
through Python, I used 'os.environ['FOO']' to set the environment variable
'FOO'.)
I hope this helps anyone else who might run into similar problems. Thank
you for all of your patience and help, Gabriel!
