Typical work flow for porting c/c++ libraries?

I'm new to the whole Alchemy world and I'm also very rusty regarding my knowledge in C/C++ (which was never that good to begin with). This is making my experimenting with Alchemy somewhat difficult, since I don't know if the problems I have are related to me not understanding the C-compiling process or the library I'm trying to compile not even being possible to compile using the Alchemy gcc. I've managed to compile some of the samples in the Alchemy download and some "Hello world" level code of my own. But I've yet to fully understand the process of compiling an arbritary C-library to an swc. So, what I'm hoping for is for you guys that have more experience with this to give some pointers about the whole process by answering my questions below.
1. Are there any indicators one can look for in C-libraries to determine if they can be successfully ported? (e.g. only use ANSI-C libs)
2. What would be the typical work flow for porting a C-library after having downloaded it's source? How do you go about starting to build the C<-->AS3 interface? Do you dive into gluegen immediately, or write the glue.c by hand?
3. When should one do ./configure; make etc. to compile a library and when does one simply use gcc alib.c...?
4. Do you have any examples of simple C-libraries one could try to port? With simple I mean libraries that don't have any external dependencies to other libraries and have a relatively small source (say 5-10 files or something).
Feel free to chip in with any answers you may have. And since I'm a n00b, please use idiot-speak as much as possible

Thks for ur reply Jens.
But still it not very much clear to me.
Can you please throw some light in the bellow sinerio :
Let say I want to build an sample music player application in Linux which will be having following module
1) GUI : which contain one button : say PLAY
2) Event handler : for the click event of PLAY Button
3)Plugin for playing music : code wich actually plays the music
So GUI that is button if devolop in FLASH/FLEX
Event handler module will be written in Action Script
Plugin will be written in C which will use gstreamer framework APIs in turn . So these plugin API's should get called from Event Handler i.e Action Script code And here is the place where binding from FLASH to C API's is requried.
So in the above senirio the actual execuable of the application will be nothing but swf file only.
Can I use Alchemy as a glue for binding FLASH & C??
Plz correct me if I am worng.
Please share ur thoughts ...
Thanks in Advance

Better work flow for final audio mix

Hi everyone,
I just finished a 20min documentary shot on miniDV. I did the offline cut on my Powerbook G4 then took it to a post house for online and recording the narration and final mix.
They exported my project to Pro Tools for the audio work. Evidently, when exporting to PT, all my level settings and audio transitions are lost, and we had to re-mix everything from scratch.
Is this the typical work flow? This is my first paid gig as director/editor, so I'm new at this. But it seems quite ineffiecient.
Is there a way to export my audio with all my audio settings intact? or at least the level settings. That way, the mixing engineer can fine-tune my rough mix rather than re-mixing from scratch. I'm wondering because I'm cutting another 20min piece where the audio mix, as rough as it is, is quite intricate, and I'd hate to have to re-do it all in PT.
I suppose one way around this is to work with Soundtrack Pro. But I'm living in Vietnam, and the post houses/recording studios all use Pro Tools.
Thanks.

When we send out audio for sweetening we export the show as an OMF 2 file. This allows the PT folks to start with your exising clips and settings and then change them accordingly.
From FCP you select your sequence and goto file>export>Audio to OMF. We usally give them a version with transitions and one without selectable on the export window. Once the OMF file is created you then image to a disk and hand it over. In return, they will give you bavk an OMF file which you reimport into your show and sync with your show. If your show starts at the 01 hour mark, start the show with one frame of bars and tone. Then have your show start two seconds later. This will make it easy for you to match back up. Also, you should give them a QT of the show with the same one frame of bars and tone for a visual reference for them.
Hope that helps.

Anybody got a better work flow for backing up multiple shoot day projects?

Many of my projects are shot over multiple days. I import media at the end of each day and back up the event to another drive before deleting media from cameras/cards. So on day 2 I have one of three work flows for updating my back-ups.
1. If I'm feeling lucky. I delete the previous back-up project from the back-up drive. And then make a new copy of the original event and add the date to the title after the word copy.
2. I make a new copy of the event to the backup drive and date it. When it's done copying and been verified I delete the back-up event from the same back-up drive.
3. I've just started copying new clips from the original media folder in the original event to the back-up project. It's more work keeping track of all the newly added media files and there is more chance of making an ommision.
Anybody got a better work flow for backing up multiple shoot day projects?

What you need:
You will need two identical external drives and a copy of Carbon Copy Cloner. CCC is free. The drives could be USB 2 if all you are doing is backing up. If you plan on editing with the drive(s), you'll want firewire. Each needs to be large enough to contain the raw card contents for the duration of your gig.
The Process:
At the end of the first day's recording, connect the two drives to your computer (if firewire, daisy chain them / if USB, you'll need two USB 2.0 ports)
On the first hard drive (Drive 1) create a folder - call it BigDealLecture
Inside of BigDealLecture, create a folder and use the nameing convention "BDL_Date_card number for that day" - so if you used 2 cards today, you should create BDL_2012-02-15_01 and BDL_2012-02-15_02
Attach your card reader or camera to the system.
Lock the cards so they can not be erased
Insert Card 1 into the reader
Select ALL contents of the card and copy them to the folder you created for the first card for today
When it is complete, eject the card, insert card 2, copy its contents to the folder for card 2
eject the card
Launch CCC and do a clone of Drive 1 to Drive 2. You can set it to do a complete block by block clone or an incremental backup. Either will work.
When finished cloning, test a random sample of the clips on both drives to make sure they work.
When satisfied the copies work, put Drive 2 in the hotel safe.
Put the Drive 1 in a place where you can grab it if there is an emergency in the night and erase the cards to get ready for the next day.
Take Drive 1 with you to the lecture site the next day.
Rinse and repeat daily.
When the conference is over, send one of the drives via FedEx or some other same day service to your office. Pack the second drive in your bags for the trip home.
A note: If you have enough downtime durning the conference between obligations, you can do the transfer from the cards to Drive 1 on site and do the clone when you get back to your room. Don't unlock and erase the cards until you are satisfied the copy/clone process was without incident.
Have fun.

HD work flow for downloadable quick times

We are putting up video clips for press sites to download - these clips are currently being used in mostly FCP and Avid. We are generating our clips from ArtBox (which only supports DV 25). We currently are supplying Mpeg-2, DV25 AVI and DV25 MOV files for download.
Question...We are wanting to supply HD content. Does any one have a suggested work flow for this delivery?
We are using FCP. I am thinking we ingest using DVCPro 50 or Pro Ress 422 and export using H264. This of course does not create the AVI of MPEG-2? We are trying to supply at least three file choices.
Any thoughts?

H.264 is only for presentation...right. Wouldn't want to get that for editing.
ProRes isn't really what you want either, I don't think. What it does is make Uncompressed HD quality files fit into an uncompressed SD data rate. That is stil a bit high for web delivery.
Not sure what you'd use. For SD clips I'd typically get Photo JPEG A files....then I'd convert into the codec I needed. I'll let someone who might know more than me in this area take the answer on this one.

Triggering a sub work flow for multiple users at same time.

I have a scenario in which I have created sub workflow as an activity for approval process. This sub work flow should be triggered for multiple users at the same time and their decison is independent of each other.
This is like creating multipe instance of the same sub work flow and then the sub work flow runs indepedently as a new work flow for each of the approver and the process is completeded for approver independently.
How can this be achieved?

Tyr to do like this,
1. First include the subworkflow in the main workflow template.
2. Now include standard Block Step in the main workflow template.
3. In the block select the block type as ParForEach.
4. Before doing the 3rd point make sure that all the agents for whom you want whom you want to initiate the workflow, populate them in a Multiline conatiner element.
5. Once completing 3rd and 4th points open the block step under the tab ParallelProcessing assign the multiline container element name in the for e;g if the multi line container element name is COSTCENTER then do the binding like below. the conatiner element COSTCENTERLINE is created by default once you include the multi line conatiner element under parller processing tab.
&COSTCENTER[&_WF_PARFOREACH_INDEX&]& --------> &_COSTCENTER_LINE&
Now assign the agent of the subworkflow as COSTCENTERLINE , imean if suppose you have 3 entries in the internal table then three separate and for three different agents the workflow is instantiated.

Regarding work flow for credit block release in sales order

Dear Experts,
Kindly help me with work flow-
my scenario is if customers credit limit of 5000$ exceeds in sales order it should be blocked and notification should go to authorize person through simple mail to release this block.
for this i have done settings in out control i have used output type krml and determined partner as employee responsible to release block in customer master but mail is not triggered to authorized person for credit block and how i can create work flow for this so that authorized person should get notify for credit block as well he releases block also.
Regards
Supriya

Dear supriyaparimal,
Please find the below points to fix your issue.
1. Configure the out put determination by using the condition type KRML.(Hope oyu have done it already).
2.Maintain the condition records in VV11 for condition type "KRML"
3.Then select the condition record and click the communication tab .
4. If you want to give any information you can use "Note for recipient".
5. If the information has to be sent to relevant person you recipient name in the recipient column.
Save the documnet.
If you raise the sales order and if it is blocked then system automatically send the information to respective person.
You can get this in formation in ""SBWP" transaction code.
Check the in box, the information what you have mentioned in the condition records will be appeared.
Please let me know if you have any clarifications

Re: Work flow for resource / work center in MEINT

Hello Experts,
We are working on SAP ME 15.0 recently installed. We are trying to send the work center from ECC to ME. In MEINT we see only the following work flow for work center / resource:
As can be seen, LOIWCS02 is not there. When we sent work center (category 9100) with LOIWCS02 IDoc type, it failed in MEINT. But when we sent work center from ECC (category 9100) using IDoc type 9100, it was processed successfully in MEINT but it created work center in ME.
The other component LOIWCS02_ME_RES or LOIWCS02_ME_WC is not getting called. What is the possible reason and resolution?
Would be thankful for any feedback on this.
Thanks in advance
Srinivas

Hello Alexander,
Thanks for the quick reply.
As per the help document, the work center category 9100 is supposed to create a Resource in SAP ME but it ends up creating work center in ME.
If you see the screen shot I had put in my query, I see that there are three work flows - one for LOIWCS03 and the other two for LOIWCS02_RES and LOIWCS02_RES. Would this make any difference since I would expect that the work flow for RES and WC should also be in line with LOIWCS03?
I will be asking my tech team to raise a support incident for this. Meanwhile I would appreciate your reply on this.
Thanks
Srinivas

Work flow for Goods issue MIGO_GI

Hi friends,
I want to develop a work flow for good issue MIGO_GI transaction. Is there any standard work flow this scenario.
When I deliver the 4 materials, the Material cost is 100*4 = 400, if the Material cost is greatr than 500, mail should trigger to the manager, if it less it will go to the first approver.
please advice me in this.,
regards,
Ajay

I think no stanadard workflow will provide you with such a validation, Better to design your own customized workflow template,
Follow the below steps.
1. Open PFTC select the task type workflow template
2. Click F5 and define the relevant fields and make the agent assignemnt for the workflow template as general task from the menu addtional agent ---> agent assginement --> maintain --> general task.
3. Check the BOR BUS2017 this might be useful.
Check the method GoodsMovement.SAPCreate and its parameters interface, if you can get the total values of the then include a condition and validate th total cost if is satrisfyies send mail and workitem to approver, if it does not satisfy then send only workitem to approver.
Check the below BADI's
MB_BAPI_GOODSMVT_CREATE        MB_GOODSMOVEMENT
MB_BATCH_MASTER                MB_GOODSMOVEMENT
MB_DOCUMENT_BADI               MB_GOODSMOVEMENT
from where you can trigger your customized workflow by using the standard fm SAP_WAPI_CREATE_EVENT or SAP_WAPI_START_WORKFLOW*
