I'm trying to use a makefile to build my application, but I can't
figure out how to run systools from the erl commandline. I want to run
the following command:
systools:make_script("environ", [local]).
...but I can't seem to express that.
I've just added another module to my build system that creates the
.boot and the .tar.gz, but is this necessary?

Starting with erl -s or erl -run makes it possible to pass
arguments as atoms or lists. So in your case I guess you
would have to write some "glue" module that takes only
atoms (or strings) and pass them on to the make_script
with right types:
erl -pa `pwd` -s mygluemodule make_script environ local -s erlang halt
Or is there a better way?

That's pretty much what I did. It just seems unnecessary.

Have you checked the builder program.
Qoute from from doc:
>>
This program compiles .rel, .script, .boot and sys.config files for erlang
applications. It supports incremental and recursive builds, and is intended
to be (much) easier and safer to use than doing it all manually.
<<
It can be checked out from the jungerl project at sourceforge.net
Otherwise Joes old ermake might be handy:

There is a module `target_system.erl' listed in the `System Principles'
User's Guide. That module might be handy.

Dustin,
Here's what I use in my make files. The erlc program recognizes
.rel files and builds .boot files automatically.
-Vance
ERLC = erlc
ERLCFLAGS = +no_debug_info +warn_unused_vars -W -v
EMULATOR = beam
%.boot:%.rel
$(ERLC) $<
%.tar.gz: all %.boot
$(ERL) -noshell -run systools make_tar $* -run init stop

Oh, excellent. Your makefile sample got rid of a whole module for me.
Thanks!

I wrote the following function that will apply any function from the
command line.
%%--------------------------------------------------------------------
%% _at_doc Allows any function to be called from the command line via erl
-s
%% all arguments should be passed in the following manner:
%% erl -s mod func "arg1. " "arg2. "...
%% <pre>
%% Variables:
%% MFSList - a list containing the mod func and a list of args to apply
comming via erl -s
%%
%% Types:
%% MFAList = [Mod, Func|Args] Example [file, list_dir, '"/var/log". ']
%%
%% Example Invocation:
%% erl -pz ../ebin/ -s fs_lib s_apply io format ""hello ~p". "
"[world]. "
%%
%% </pre>
%% _at_spec s_apply(MFAList) -> void()
%% _at_end
%%--------------------------------------------------------------------
s_apply([Mod, Func|Args]) ->
io:format("fs_lib:s_apply args before parsing: ~w~n", [Args]),
TokedArgs = lists:map(fun(ArgAtom) ->
{ok, Toks, Line} =
erl_scan:string(atom_to_list(ArgAtom), 1),
{ok, Term} =
erl_parse:parse_term(Toks),
Term
end, Args),
io:format("apply the following: apply(~w, ~w, ~p)~n", [Mod, Func,
TokedArgs]),
apply(Mod, Func, TokedArgs).
so to run this function from the command line for a function like
io:format("hello ~p~n", [world]).
you would invoke
erl -pz ../ebin/ -s fs_lib s_apply io format ""hello ~p". "
"[world]. "
notice that all the arguments for the function that you want applied are
strings containing terms. The containing strings are terminated with a
.<space? see the docs for erl_scan and erl_parse for an explaination.
Make sure that you properly escape any of the terms contained by the
strings.
Cheers,
Martin
