EXPORT LDFLAGS=-pg

./configure debugflags=”-pg -g” # note — might need to for sure not –enable-shared

make

edit Makefile, add -pg to LDFLAGS, possibly to the lines around it, too

make

make install

Currently it appears

1) jruby has ruby2java which uses annotations to know how.

annotate :go :boolean => :boolean

2) druby has a parse tree to lookup dependencies (ocaml) and “see if anything doesn’t fit the duck typing” based on its dependencies.

3) ruby2c has a parse tree to lookup dependencies (ruby) and, from the types currently passed in, convert methods to c.   Haven’t quite gotten it to work yet.

4) duby uses its own syntax:

go(a => :boolean); return a; end

5) druby also can add “extra dynamic tests” which wrap methods and watch what things are passed to them during runtime.  When the script executes, it re runs (?) its dependencies parse tree to look for discrepancies.

So basically there’s nothing out there that’s automatic, but there’s some tools that, if combined, would work (note–haven’t yet gotten ruby2c to work–if it did that might be real nice).

Assuming that  ruby2c doesn’t work, the shortest path would seem to be somehow combining a dependencies analyzer with ruby2java to generate final objects.

Thoughts?

I suppose one way would be to fork the current process, then have gdb attach to it and call “backtrace” then unattach.

here is the example, in linux:

(gdb) bt
#3 0x0815e92b in vm_call_method (th=0×8350480, cfp=0xb7b66ee8, num=1,
blockptr=0×1, flag=8, id=7688, mn=0x82717b4, recv=136505600)

#6 0×08159326 in loop_i () at vm.c:524
…

ruby 1.9.2 has the possibility of a more verbose debug output, too (somehow)– you might be able to tie into that.

Unfortunately, in mingw I can’t seem to get gdb attach to print out *anything.*

don’t know how yet, but…here’s a beginning

C:/ruby19/bin/ruby.exe extconf.rb install nokogiri –platform=mswin32

iconv is missing. try ‘port install iconv’ or ‘yum install iconv’
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

appears it may not be under “all programs” -> accessories -> communication -> remote desktop

it might be under

Go figure.

git clean

collect2: installation problem, cannot exec `C:\dev\ruby\rubyinstaller\sandbox\mingw\bin\..\lib\gcc\mingw32\3.4.5\..\..\..\..\mingw32\bin\ld.exe’: Exec format error

might mean “a corrupted mingw gcc” since if you search for ld.exe’s, shouldn’t they be the same?

maybe rebuild? what the heck?
