Hi, 

I had a try to see whether I could make GUB
also produce a MinGW installer for Git.

You can download the result at 

http://lilypond.org/mingit/mingit-1.4.9993-1.mingw.exe

the odd version number was because I was too lazy to write code
to extract the version number from the repository automatically.

I don't actually have a windows copy, so it's basically untested.
However, I did succeed in running rev-list in wine.


PS. I'd be interested in comments on using GUB from others.
GUB is a cross-compiling build tool, probably best described
as a "Poor Man's Conary".
 
Once I have the boilerplate code committed, building this 
installer should amount to  

  darcs get  http://lilypond.org/vc/gub.darcs/ gub
  cd gub
  make -f Makefile.mingit bootstrap mingw

(yes, GUB itself is still hosted in Darcs. Shoot me.)

Hi,



I played a little with it. IMHO it makes no sense to use it without a 
bash, and without less. For example,

	$ git init
	$ git add git.exe
	$ git status
	$ git commit -a -m initial
	$ git show HEAD

do not produce any output when issued in cmd.

Also, many scripts rely on bash and/or perl, so you'd have to include 


I will.

Hi,


Side note: Since "ln <src> <dest>" in MinGW is really a copy, not a hard 
link, this gets rather big (44M here).

Which makes me think if we should just disallow the "git-<builtin>" on 
Windows, since sooner or later, Git will no longer be used from the 
command line on Windows.

And another thing hit me there: Are you sure that all works well if you 
change the install path from "C:\Program Files\Git" to something else?
Without explicitely setting GIT_EXEC_PATH?

Ciao,
Dscho

I have no idea. The installer just plonks the files into C:/P F/Git/
and adds that to $INSTALLDIR/usr/bin/ to $PATH

Indeed: for now, this is intended for people clueful enough to install
bash and perl on their own.  Adding bash itself should be easy, but
I have no idea how to make cmd open the scripts with bash automatically.

The thought of x-compiling perl makes me shudder.

Hi,


Would be nice to include them, though. In this case, you can add a 

You don't want to tell me that you x-compile Python when bundling 
LilyPond, do you?

See

  http://lilypond.org/vc/gub.darcs/patches/python-2.5.patch
  https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1597850&group...

I freely admit that it doesn't work very well, because the python build 
procedure is rather naive when it comes to detecting installed modules.

Hi,


So you _do_ build it? Phew.

A few months back, when we had that nasty Aussie on lily-devel whining 
about not being able to compile LilyPond on Windows, I tried to build 
_all_ of the dependencies on MinGW, including Python. Needless to say, I 
gave up...

BTW do you have side branches in that darcs gub repository? If not, I'll 
try to leech it into a git repo with tailor (I do not want to install 
darcs on all my machines, just to play with gub).

Ciao,
Dscho

No, but I have a conversion running here.  I'll publish it once it's done.

Hi,


Thank you very much!

Just out of curiosity: What do you use to convert it? Tailor all branches, 
then stitch them together? (With tailor, stitching is possible as long as 
you did not merge branches: the commit objects _will_ be identical, since 
even the commit timestamps are derived from the source repository.)

Ciao,
Dscho

A simple linear import of all the patches. Since Darcs
uses patch based storage, I think it's not possible to accurately map a Darcs
repository onto a Git one without creating branch spaghetti. 

I have never grokked how tailor is supposed to work, so I use a home made
script.

That was spoken with hybris.  Bash uses a regular gnu autoconf build
procedure, so making it build is much less of a pain to than massaging eg.
Python. However, it is a unix shell, and as such it does fork() all
the time. Hence, it is necessary to use Cygwin (or its derivative MSYS)
for running Bash.

A good reason to get rid of bash scripts.

Strange, those are builtins, not?  I recall that we also had
some issues with lilypond stdout printing things inside CMD,
depending on whether -mwindows is on the link line.
Details escape me, though. 

Jan?

I didn't either, but Google says

   This is a windows limitation.  GUI apps (apps created with -mwindows)
   can't send output to or receive input from the console.

That seems right, I remember that we chose to use -mwindows to get
rid of the flashing black console silliness.

Greetings,
Jan.

Can you confirm to me that these do actually work?

Hi,


Apart from commit, which is a shell script, they appear to work. Only no 
uoutput :-)

can you check out the -2 build, at

to see if this is better?

Hi,


Unfortunately, today was the last day for me at a company where I have 
access to Losedows. I'll try to get hold of another machine, and try 
there, though.

Ciao,

Yes, much better.  There's still the bash script problem, maybe
these should be replaced with python?

Hi,


Hahahaha!

This is not meant as laughing _about_ you... Along with others, I worked 
very hard to get rid of that naughty dependency to Python.

IMHO the best way for Git is to go builtin. It is the only way to 
guarantee portability to many, many platforms without a dependency 
nightmare.

Who knows, maybe Git will run on VMS yet?
