connect Modelica with arduino by firmata

I would like to connect my arduino with modelica by using the firmataprotokoll and the arduinolibrary.
But the compilation always fails because of the error:
LINK : fatal error LNK1181: cannot open input file 'ModelicaFirmata.lib'
Does anybody have an idea how to fix this problem?
The error was caused by a wrong version of the Modelica-Arduino-Library. Instead of downloading the code I should have downloaded the latest release on github.
In addition it is important to choose the right compiler in Modelica (Visual Studio 2015).

basic_client which is built with Makefile BusAttachment::Connect failed

I just built standard core 15.09a on linux and run sample apps basic_client.
This one built by scons.
bin/samples/basic_client works fine.
However, I built cpp/samples/basic/basic_client with Makefile.
It does not work. It shows an error
"0.232 ****** ERROR ALLJOYN external ...e/src/BusAttachment.cc:560 | BusAttachment::Connect failed: ER_OS_ERROR
BusAttachment::Connect('') failed.".
So, I launched the bin/allhoyn-daemon, then no error occurred.
What is difference between scon and Makefile version?
Additionally, where can I get the information of application under the bin directory?
I searched the web-site of AllSeen and couldn't find any info.
As i know, the error that you got when build with Makefile happens because basic_client hasn't alljoyn router inside, with scons it runs fine because it compiles with BR=on and some flags:
-lajrouter -lBundledRouter.o -lssl -lcrypto

XCode 4.3 - Build error "missing required architecture armv7"

After upgrade XCode from 4.2 to 4.3 I've got below problem. I can't build it.
Do you guys have idea how can I resolve this problem? even some clue would be helpful to me.

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I was getting the same linking error for the Simulator after upgrading from Xcode 4.2 -> 4.3.1. I noticed that new projects in 4.3.1 do work with Unit Tests, so just compared the project differences.
What fixed it for me was:-
Select Project in project navigator
Select Test Target
Select Build Settings
Go down to Framework Search Paths and single-click it
Delete whatever is there
Enter $(SDKROOT)/Developer/Library/Frameworks $(DEVELOPER_LIBRARY_DIR)/Frameworks
If you had any custom frameworks, add those back
Actually, Unit Tests run fine on the Device, too.
Looks like this was either an accidental (or on purpose) omission on Apple's part.
If (and only if) you are a registered Apple Developer, you can log into the Apple Developer Forums and if you copy this linked search query into your browser address bar, you will see other people have had the same problem.
For now, it looks like you can only use SenTestingKit on the simulator.
I had a similar issue with Xcode 4.4.
My solution path:
Removed SetTestingKit.framework from the main target's (the system under test) "link binary with libraries", leaving it in the test target as is. Not sure why it ended up there in the first place.
I believe this bug is now fixed in Xcode 4.4.1
Using xcode 4.6 and trying to add facebook SDK 3.1 I had this problem because I didn't select to add the files to my test target.
You should check both targets when you copy the framework.
I just upgraded to 4.3.1 There is a problem with SenTestingKit framework. I removed the test source code from the project, it builds ok. And it can run on 5.1 device. But I got _dyld_dyld_start error when I ran it on simulator. I had to remove SenTestingKit from the project to make it work on simulator.

New Static Library has build error "libtool exited with code 1"

I created a new static library in my iOS project and now I'm getting the build error
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/libtool failed with exit code 1
How do I go about debugging this?
To see the actual output and not just the error message, try building your target or scheme with xcodebuild from command line.
I had a problem with the same error message. In my case, I couldn't build for the simulator, but it worked find when building for the device. The output from xcodebuild confirmed that Xcode could not set the proper architecture to build for the simulator.
Long story short, it turned out that one build setting was corrupted. The Mach-O Type setting in the Linking category was set to Relocatable Object File for some reason. I switched it back to Static Library and the error disappeared.

Depmod - unresolved symbols in rt73 module

I'm trying to install a linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the module. However, whenever I do a "make install", the make script executes a "depmod -a" command which then complains with the message: "Unresolved symbols in /lib/modules/2.4.37.9/extra/rt73.o".
I then executed a "depmod -e" command to show unresolved symbols and it indicates the following information:
request_firmware_Rsmp_38ce5074
release_firmware_Rsmp_33934162
I did a grep on the above information and it showed no source files making reference to it. I searched for it on google and it returned no results. Can anyone help?
I found out the reason - it was missing the firmware_class module. I had to rebuild kernel modules with the experimental feature CONFIG_FW_LOADER as a module which is found under Library routines\Hotplug firmware loading support. After loading the firmware_class module, the rt73 module loaded successfully also.
