a small error in the documentation (compilation instructions)

[Matej Kosik]

Hello,

I have noticed a small error in the documentation. Here:
http://people.redhat.com/~rjones/bitstring/html/Bitstring.html#2_Compiling
are instructions how to compile a stand-alone Ocaml program that takes
advantage of bitstring syntax.

One of the two suggested commands:

ocamlc -I +bitstring -pp "camlp4of bitstring.cma
bitstring_persistent.cma `ocamlc -where`/bitstring/pa_bitstring.cmo"
unix.cma bitstring.cma test.ml -o test

does not work. After some experimentation, I have found a similar
command that works:

ocamlc -I +bitstring -pp "camlp4of -I `ocamlc -where`/bitstring
bitstring.cma bitstring_persistent.cma pa_bitstring.cmo" unix.cma
bitstring.cma test.ml -o test

[Richard W.M. Jones]

Thanks. Does -I +bitstring work as well?

Rich.

If you ask, if the command can be simplified to:

ocamlc -I +bitstring -pp "camlp4of -I +bitstring bitstring.cma
bitstring_persistent.cma pa_bitstring.cmo" unix.cma bitstring.cma
elf.ml -o elf

then, I think, the answer is no. If I tried it, I've got an error
message:

Camlp4: Uncaught exception: DynLoader.Error ("bitstring.cma", "file
not found in path")

OK, thanks for trying it. That's odd ...

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

It can be easily reproduced. The archive:
http://www2.fiit.stuba.sk/~kosik/tmp/elf.tar.gz
contains relevant files.

I have tried this on two Debian stable systems.
"camlp4of" options:

-I `ocamlc -where`/bitstring

cannot be replaced with saner variant:

-I +bitstring
