[GD-Windows] Makefile woes

[Brett B. <res...@ga...>]

Any makefile experts that can spare a moment? Having problems with makefiles
on Windows (using GNU make under Cygwin) and can't seem to figure it out or
even how to google it. 

If anybody can point me to a mailing list or forum that is more appropriate,
please let me know. All the lists I found so far aren't helpful.

1. I want to check for the existence of a directory, and if it doesn't exist
create it.

Most of the linux/unix examples do something like:

.PHONY: $(SUBDIR)
$(SUBDIR):
	@[ -d $(SUBDIR) ] || mkdir -p $(SUBDIR)


Obviously the mkdir needs to become md, but it seems to me that the brackets
and the or'ing are using the shell to test for the directory? I don't know
shell commands at all and it's frustrating trying to figure out this stuff.

2. I want to do some printf style debugging beyond the -d makefile switch.
Something like:

<some makefile commands>
echo "You got here"
<some more makefile commands>

But this doesn't work. What is the way/format to output messages anywhere
during the make build?

Any help appreciated...

It's been more than 2 years since I had to maintain makefiles, so this 
is all coming from memory.

[ is a exe in unix, but more likely a shell builtin these days.  It 
might be a synonym for 'file'.  But it's using circuit evaluation to 
test if $(SUBDIR) exists, and if it doesn't then it creates the directory.

But if you're running under cygwin, you should have the unix shell, 
shouldn't you?  (And a version of the mkdir)

Make builds dependencies.  You can only run commands as the result of 
make deciding it needs to build a dependency.

$(SUBDIR):
    @echo Creating dir $(SUBDIR)...
    @[ -d $(SUBDIR) ] || mkdir -p $(SUBDIR)
    @echo Done.

Doesn't really clarify anything, does it...

Shouldn't it be

@echo "you got here"

?

not that i've touched a makefile in over two years so.....

Learning make is like learning any other language; you can't expect
to go from newbie to proficient in a single week of work. If you don't
know make syntax, and don't know UNIX command line shells, you may want
to ask yourself why you're trying to use make syntax and UNIX command
line shells to accomplish whatever your task is. Does someone else in
your organization require it? If so, use them as a learning resource.

There are some resources you need. The first one is a reference to the
BASH shell and the typical UNIX command-line utitilies (such as '['
which is an alias for 'test'). Because you're using Cygwin, you have
access to mkdir, test, cp, sed, and the other commands; you should use
them if you're using the Cygwin make.

If you want a reference manual for GNU make, try an online copy, such
as http://theory.uwinnipeg.ca/localfiles/infofiles/make/make_toc.html

If you want an example of a set of simple make files that manage to
build a number of libraries and applications without recursively
invoking itself, and which also collects full dependencies automatically
(assuming you're using GCC), you can look at my sample here:
http://www.mindcontrol.org/~hplus/makesample.html


In conclusion: if you're doing this for your own edification, then keep
going. It might feel frustrating, but you ARE learning an entirely new
language; don't expect mastery in the first week. If you're doing this
for someone else, and that someone else expects you to master it in a
single week, then someone needs to adjust their expectations, or do it
themselves, or help you along (obviously, the latter would be best
overall).

[GD-Windows] MAX Crashes During Batch

[yogiwp <yo...@gm...>]

Hi,

I wonder how people deal with 3dsmax export crashes during
batch data build? It happens randomly and it's not the exporter's
fault. Reseting the scene before loading new file helps to reduce
crashes a bit, but not completely.

Thanks in advance.

The file that the artists produce and check into the build is not the 
.max file; it's a rich, exported format that captures whatever we will 
need. The real asset build then builds from this intermediate format to 
an actual optimized format.

The artists still revision control their .max files, but they do that on 
a server they organize however they want, without any 
engineering-imposed structure. The intermediate files, however, have 
that structure.

Cheers,

Re: [GD-Windows] MAX Crashes During Batch

[yogiwp <yo...@gm...>]

Well, unfortunately it's kinda late for this project to switch into such process.

I really was hoping for 'hacks' to get around this. Max crashes should not
stop the build.
One idea is to 'detect' if max hangs and kill it, continue the build, and then
repeat the build (because different build runs crash on different file).

I'm clueless on how to 'detect' max crashes. And I'm not even sure if this
is a good idea. Anyone?

Thanks.

In the past I've had a little util that sits doing a FindWindow on the 
error dialog box title every second or so then just take the resulting 
HWND and do SendMessage(hwnd, WM_CLOSE) to it.

Good idea! I think I can do something similar.

In our case, max is started in 'silent' mode causing it to not show any dialog box
(apparently including errors boxes). This is necessary because otherwise it will
show dialogs about missing texture etc. and stops the build.

So what I'll try is monitor max' window caption, and if it doesn't change after a
while I know max is stuck.

Thanks all.
