I've written some application code using JMF, but would like to switch to FMJ to make delivery easier.
Unfortunately, on my Windows 7 laptop (where JMF works fine once installed), I downloaded fmj-20070928-0938.zip, uncompressed it, and ran fmjstudio.bat. As soon as I click on the webcam icon, I get errors which start with "WARNING: com.lti.civil.CaptureException: java.lang.UnsatisfiedLinkError: C:\Temp\fmj-extracted\native\win32-x86\civil.dll: Can't find dependent libraries"
Any suggestions?
Although it is probably not a complete answer, a partial answer is that FMJ uses 32-bit libraries. I am fairly sure I was using a 64-bit java.
On a different Windows 7 computer I successfully got fmjstudio to run using a 32-bit java. Next step is getting it to recognize the camera for my own app rather than fmjstudio.

I initially thought that there was some way to be able to run Swift on Windows using emulators, or some other program that allowed Windows to compile and run Swift, but after browsing here a few times I learned that there is no(legal) way to do it. So how is it possible that you can do this at SwiftStub thru your internet browser?
You can check it out here:http://swiftstub.com/
Easily! They compile and run code on a Macintosh Server on their end, and just feed you the result in a web-based app. You're not running the code, they are. You just get to see the end result.
I tried to learn "Lena's reversing for newbies", when some trouble arise.
I start Pixtopian Book with ollyDbg, then try to have MessageBox with message about uregistered version.
Then i switch to OllyDbg, stop program executing and press "Alt+F9" for "Back to user mode" which stop the program after it exit from DLL.
But after this program does not work, it's frozen and does not respond to my actions.
If i turn off "Back to user mode" program normally work.
What's the problem? Can i try to use "Back to user mode" in IDA (uses WinDbg) or some other debugger and How i can do this? Can i repair it function in OllyDbg?
P.S. It's like the program stopped and didn't run after use "ALT+F9".
/Sorry for my English, i'm just learning ;-)/
First of all, Ollydbg is meant for 32 bit platform. It means that it will run only on a 32 bit OS and can only debug 32 bit apps.
In x64 Operating Systems (specifically Windows) there is a feature called compatibility mode that lets you run 32 bit apps. The 32 bit code is either run by emulation or natively (when the hardware itself implements the instruction set and then it is called x86-64).
So, when you try to run Ollydbg in a x64 environment it will run, but you will experience problems like the one you are facing. It occurs because Ollydbg is run in an emulation mode. Being a debugger it needs access to the registers and other system structures, which it is denied. What it can see is a virtual image of the system.
So the solution to the problem is using a Virtual Machine.
You would install a 32 bit OS in it and debug the app using Ollydbg. As far as Virtual Machines are concerned, I would recommend VMWare. You can use either the workstation or player version. The latter is free but does not support snapshots.
Other solutions are Virtual Box, Parallels Workstation and Microsoft Virtual PC.
The disadvantages of them are that Virtual Box does not support hardware breakpoints, Parallels Workstation is no longer supported as of 2014 and moreover there you would get a BSOD if you try to single step through FPU instructions. I have not tested Virtual PC though.
Note : Ollydbg does not supports x64 but its author is working on a x64 version.
I just learned how to update changes to the exe file for ollydby v 2.01e.
suppose I wished to change a jl command to a jmp; do this by clicking the executable modules button, choose the file and right click to view the file. then record the changes and save file. The saved file also has a backup in case something goes wrong.
I just did a thorough learning of the pixtopian file. When I downloaded
that tutorial I get the file pixtopian107.exe only. Since it didn't agree with the tutorial I investigated further. That file is an installation file. It produces a regular pixtopian.exe file which is the file you wish to play with.
I also noticed that in running the file it never enters the main module.
this is because of the TLS callback. right now I am trying to learn how
to overcome this which is how i came to this site in the first place.
I am using ollydbg vs2.01e very effectively.
Another thing, in vs 2.01e I am still trying to save changed data. Until I succeed I am recording the changes in the exe files using hex editor.
From my experience I can tell that this functionality won't work on Windows 7.
On Windows 7 64bit --> Won't work at all.
On Windows 7 32bit --> Will work partially, but only when using option "File>Attach" in OllyDbg.
For me, best solution was to use Windows XP 32bit, then it worked fine.
I have some customers/candidate who complained that my program doesn't work on their Windows 7 64 bit version (confirmed with screenshots). The errors were strange, for example:
in the trial version i am
getting a error message whenever i
click on \"mark\" \"delete\" \"help\".
error msg is: Access violation at
address 0046C978 in module
\'ideduper.exe.\' read of address
00000004
windows 7 ultimate 64bit. i7 920
#2.67GHz 9gb or ram
'Mark', 'delete' and 'help' are just standard TToolButton on TToolbar.
The other example is failing to get a thumbnail from IExtractImage.
I have told them to try Compatibility mode but still doesn't work.
The problem is when I tested it on Windows 7 HP 64-bit on my computer (which I've done it before released it actually) it just works fine! So I don't know what causing it
Do you have any advice ?Are different Windows package (home basic,premium,ultimate,etc) treating 32 bit prog differently ?Are the newer version of Delphis (I use 2006) more compatible with 64 bit Windows ? Do I need to wait until 64 bit compiler out?
Thanks in advance
Your best bet in my opinion is to add MadExcept or EurekaLog or something similar to your application and give it to the customer to try again. MadExcept will generate log with stack trace, which will give you a clearer view of what is happening there.
To answer 2nd part of the question, 32bit Delphi programs work fine on 64bit Windows 7. I think it's more likely you have some memory management problems and the customer just happens to stumble upon them while you don't. Use FastMM4 to track those down.
Your applications is trying to access an invalid pointer. Changing environment may surface issues that are hidden in others. Check your application, and use FastMM + JCL+JCVL/MadExcept/EurekaLog to get a detailed trace of the issue. Some Windows APIs may have some stricter call requisites under 7 and/or 64 bit, but we would have to know what your app actually cals.
A free alternative to MadExcept is JCL Debug stuff. However it is less thorough and doesn't include the cool dialog box to send the stack trace to you via email, or as a file you can attach and manually email.
MadExcept is worth the money, and it is free for non-commercial use. You could try it first on your own PC, observe its functionality, and be sure it functions the way you want, and then buy it.
If buying Delphi is worth it (and it is!) then buying mad Except is a no brainer. But if you insist on rolling your own, JCLDebug (part of jedi code library) is also pretty nice.
Give them a stripped down version of your app and see when the problem goes away. I am betting it is your code as I never had any problems with my (hundreds of) W7/64 clients.
I'd be willing to bet it's an issue in your code. The reason it's failing on your customer's machine and not yours is that your machine probably has the default Data Execution Protection (DEP) enabled (which is turned on only for essential Windows programs and services), while your customer's computer is actually using DEP as intended (turned on for all programs and services).
The default setting (which is compatible with older versions of Windows, like 95/98/ME), allows software to execute code from what should be data segments. The more strict setting won't allow this, and raises a system-level exception instead.
You can check the settings between the two by looking at System Properties. I'm not at a Win7 machine right now, but on WinXP you get there by right-clicking on My Computer, choosing Properties, clicking on Performance Options, and then selecting the "Data Execution Prevention" tab. Find it on Vista/Win7 by using the Help; search for Data Execution Protection.
The solution, as previous answers have told you, is to install MadExcept or EurekaLog. You can also get a free version as part of JEDI, in JCLDebug IIRC. I haven't used it, so I can't vouch for it personally. I've heard it's pretty good, though.
If you don't want to go that route, set a breakpoint somewhere in the startup portion of your app (make sure to build with debugging info turned on). Run your app until the breakpoint is hit, and then use the IDE's Search->Goto Address (which is disabled until the breakpoint is hit). Enter the address from the exception dialog (not the one that's almost all zeros, but the 0046C978 address, prefixed with $ to indicate it's in hex) as in $0046C978. You'll probably end up in the CPU window looking at assembly code, but you can usually pick out a line of Delphi code of some sort that can sometimes give you a place to start looking.
In addition to all previous suggestions, I'll add the difference in accessing Registry under WOW64 compared to Win32. If your application is accessing Registry to read or write some settings, you should be aware of this. First, take a look at this and this page in the MSDN. On this page you will find 2 flags that determine the access you get to Registry from 32- or 64-bit application. KEY_WOW64_64KEY is the one that you should use.
In any case, I agree with others about using madExcept (or any other similar tool) to be able to find the exact cause of your problems.
A while back I was following some tutorials an assembly. I was running it all on a windows machine, compiling with NASM and then writing the compiled code to a floppy disk, then reboot and try the code. This process was long and time consuming and sadly was not on a mac. When I found out that Xcode for mac installed NASM I immediately tried to compile some code. The code compiled fine. The issue is testing it. On a mac I have no floppy (not like I want to use one) so Im not sure how to test this. I looked in to Q (kju) and found it would only emulate things on an ISO file. So I guess what Im asking is is it possible to install the compiled code on an ISO file for testing? (Note: the code when compiled forms a .bin file)
Thanks for any help
I don't know exactly what you are trying to test (a boot loader maybe?) but you don't need to reboot or boot from a disk just to run assembled code (unless it is a boot loader or something).
Either way, if you need to "reboot" to test, I suggest running an emulator. Sun VirtualBox is super easy to use and free and emulates a standard x86 architecture (including floppy drives)! So that may work for you in the short term. If you ever want to create an ISO image in the future, you can do that with the command line utility hdiutil. In a terminal window, type man hdiutil or visit the online man page for more information on using that to create all kinds of disk images.
I really hope someone can be of help to me because this problem has me totally stuck and frustrated.
Yesterday I installed a fresh and shiney new Windows 7 x64 onto a development box.
I got VS2008 installed, Tortoise SVN, did a checkout, compiled my currently project, all fine and dandy.
But when I go to run (either F5 in VS or just running the exe from the shell) I get a dialog box that looks like this:
(source: aliparr.net)
So I fiddle around and can't see an obvious problem. I bust out depends.exe, thinking maybe there's a dll missing, and I get this:
(source: aliparr.net)
So I play, finding different versions of gpsvc.dll and ishims.dll and putting them in with the .exe, No luck.
If I do a profile in depends (which follows the Output window of vs), I get this:
..

So it seems openldap.dll is the last thing to get loaded before it all goes wrong. I require this dll because I use cURL within the application to do a little JSON communicating...
I've tried playing with moving files and trying differing dlls, but honestly I'm acting a little blind here. Can someone please help or point me in the right direction?
It should be noted these dlls and setup work fine in Windows Vista x64 and x86 - is this a Windows 7 thing?
Massive thanks in advance, I might still have some hair left after this is done.
Edit
I've now realised curl.exe dies in exactly the same way with openldap.dll - I guess some windows 7 issue?
Can you/does anyone have a curl without the dependency on openldap? Is there another lightweight C/C++ library out there that'll let me fetch a document over http and do the odd http POST ?
Thanks
I had a very similar problem myself: I was developing a C program (using the MinGW gcc compiler) which used the curl library to do http GET operations. I tested it on Windows XP (32-bit) and Windows 7 (64-bit). My program was working in Windows XP, but in Windows 7 it crashed with the same 0xc000007b error message as the OP got.
I used Dependency Walker on a down-stripped program (with only one call to the curl library:curl_easy_init()). I essentially got the same log as yours, with OPENLDAP.DLL as the last successfully loaded module before the crash.
However, it seems my program crashed upon loading LIBSASL.DLL (which was the next module loaded according to the log from Dependency Walker run on Windows XP).
When looking again in the log from Dependency Walker on Windows 7, LIBSASL.DLL indeed shows up a x64 module. I managed to get my program to run by copying a 32-bit version of the DLL file from another application on my harddisk to my program's directory.
Hopefully this will work for other people having similar problems (also for the OP if the problem still wasn't resolved after these years). If copying a 32-bit version of LIBSADL.DLL to your program's directory doesn't help, another module might cause the crash. Run Dependency Walker on both the 32- and 64-bit systems and look up the module name from the log of the successful run.
I cannot answer your questions completely, I've compiled libcurl on Windows 7 Professional x64 and I don't have any issues. Although I haven't compiled it with OpenLDAP support so I suppose that's where the issue lies.
Regarding the IEShims.dll, Dependency Walker usually reports this as a missing module. Can't remember the exact reason but it was something about loading it dynamically when it's not found in %Path%.
If you however need to debug this and are on Windows 7 then try doing a hard link from %ProgramFiles%\Internet Explorer\IEShims.dll to %windir%.
Although, I see on the screen dump that it sure looks like Spree.exe isn't loaded as a x64 binary, which could very well be it. There's a difference in loading exported functions and piping or exec() a binary, the first mentioned requires that the architecture is the same for both the importer and exporter.
I've also found that mine is trying to load a 64 bit version of LIBSASL.DLL - the one that came with my 64 bit Tortoise distribution. I also only need curl for pulling a bit of JSON data. I think the best solution is going to be to rebuild libcurl from source and exclude the LDAP since I don't need it anyway.
Similar issue here. DLL dependents GPSVC.DLL and MSVCR90.DLL.
I managed to get rid of IESHIMS.dll by setting my environment variables path to C:\Program Files (x86)\Internet Explorer. Surely that shouldn't need to be done!
Is there a fix to this yet?
libsasl requires ieshims.dll, if you don't have sasl support in openldap, then ieshims.dll won't be required.
If you use windows x64 you have to copy your dll to c:/windows/SysWoW64. I have had the same problem when i wanted use pthreads in windows os 8. When I was copied pthreads dll to SysWow64 the program was run sucessfully.
