[Omake] building omake

[Sam Steingold]

I tried to build omake from sources.
I already have omake 0.9.8.5 installed, so I tried to use it:

1. svn co http://svn.metaprl.org/svnroot/mojave/omake-branches/0.9.9.x/
$ cd 0.9.9.x
$ omake
$ vi .config (edit PREFIX)
$ omake

*** omake error:
    File mk/make_gen: line 62, characters 47-54
    unbound variable: global.name

why am I seeing the "Checking" messages on each omake invocation?

$ make bootstrap
mkdir -p boot
ln -sf ../src/Makefile boot/Makefile
...

2. svn co http://svn.metaprl.org/svnroot/mojave/omake-branches/0.9.8.x

I have ocamlc version 3.11.0.

so, how do I compile omake from sources?

PS. INSTALL says "let's assume you do don't have omake already installed"
it should be "let's assume you do not have omake already installed"

PPS. the instructions in INSTALL for when omake is already present is eminently
unclear. What does "you should use your working copy to do the bootstrap"
mean?! "cd src; omake" ? "omake bootstrap"?

PPS. The reason I want to build omake is that we are unhappy with our build
process performance and we want to profile it. I want omake to collect
information on how many times it invoked each program (ld, gcc, ocamlc,
ocamlopt &c) and how long each of them took. This could be useful to others as
well, so I want to contribute the patches back.

thanks.
