I am trying to run the PumpingSystem Example in the openmodelica Fluid library using the nightly build 1.9.1+dev (r21018). Unfortunately the simulation crashes saying it failed to solve NLS at initialization.
I tried to modify the model either by creating a new one extending it (which only permits the modification of the parameters but not the structure, I understand that this is probably what extension means) or by copying the text view of the model to a new file, but then OMEdit crashes.
Will you please advise how I can create a copy that I can modify?
Thank you.
PS: I am running this on Linux, the Windows version seems to translate all libraries,creates an infinite amount of translation errors "expected package to have within ; but got ..." and then terminates with a translation error "C:/OpenModelica1.9.1Nightly/lib/omlibrary/Modelica 3.2.1/Blocks/Continuous/Internal/Filter/Utilities/normalizationFactor.mo:14:3-42:27] Error: An element with name normalizationResidue is already declared in this scope."
You can not modify the system libraries. You can only extend them.
Creating a copy of the model is currently not supported. You can follow this ticket https://trac.openmodelica.org/OpenModelica/ticket/2190
If you just copy paste the text, as you already did, you need to manually update the relative paths used in the model.

Im trying to accomplish a twincat 3 library which does things using global constants defined in the main project, like creating arrays the size of those constants and cycling trough them. However I've been unsuccessful and I wonder if this can be done. I just get this error "Error 4 Border 'cPassedConstant' of array is no constant value" when I try to build the main project. The error comes from the array defined in the library.
I've tried making a GVL with a constant of the same name to the library and then setting the "external implementation" property true but that does not help.
My goal here is to make a IO management library with filtering and such. And then I could just add it to the main project and define some constants like "cDigitalIputsCount","cAnalogInputCount" and so on.
Maybe you can get along with the new ARRAY[*] feature instead, although it is still very limited. There is no other way than to define the constant in the library.
The library concept is the same as in other environments. A library provides you reusable components. Your main project depends on the library and not the other way around. Therefore your library cannot know a thing about the project where it is used.
A confusing thing in TwinCat3 is, that you can build projects successful with programming errors inside. The TwinCat3 compiler allows broken code inside a project as long as it is not called. Therefore when you ship libraries you should always use "Check all objects".
You should check Beckhoff's feature called Parameter List. By adding a parameter list to the library project, you can re-define library constants in the project that uses the library. The definition happens in the library manager.
Image from Beckhoff's site:
I think that should do it. Of course, the other option is to use the ARRAY[*] option, which is awesome too (for a PLC programming world). The problem with parameter lists is that it is a project-wide re-definition. Using the ARRAY[*] allows the size be changed dynamically.
I would suggest using a variable length ARRAY[*], as explained in the link below (and also in the Beckhoff/Infosys, section DataTypes/Array).
The point is that you should declare the ARRAY[1..cAINs] of FB_AnalogIO in your main program (it knows the FB_AnalogIO from your analog library and can declare it with a constant size).
The PRG_IO should then be changed to either a function or function block, so that it accepts the ARRAY[*] as a VAR_IN_OUT without knowing the exact size.

I am attempting to convert parts of an Android app to iOS using Doppl, and I am getting a strange result: Doppl keeps trying to pull in android.arch.lifecycle:reactivestreams, even though I don't want it to.
Specifically, in app/build/j2objcSrcGenMain/android/arch/lifecycle/, there is a reactivestrams/ subdirectory with R.h and R.m files in it. This seems to make Xcode cranky and may explain why I had some oddities with pod install.
My app/build.gradle has compile "android.arch.lifecycle:reactivestreams:$archVer", because my activity is using LiveDataReactiveStreams.fromPublisher(). However:
The activity is not in the translatePattern (and since its code is not showing up in app/build/j2objcSrcGenMain/, I have to assume that the translatePattern is fine)
I do not have a doppl statement related to reactivestreams, because there does not appear to be a Doppl conversion of this library (nor should it be needed here)
AFAIK, nowhere else in this app am I referring to LiveDataReactiveStreams, which AFAIK is the one-and-only public class from the reactivestreams library
So, the questions:
What determines whether Doppl creates R.h and R.m files for some dependency? It's not the existence of a doppl statement, as I have doppl statements for a lot of other dependencies (RxJava, RxAndroid, Retrofit) and those do not get R.h and R.m files. It's not whether the dependency is referenced from generated code, as my repository definitely uses RxJava and Retrofit, yet there are no R files for those.
How can I figure out why Doppl generates R.h and R.m for reactivestreams?
Once I get this cleared up... do I re-run pod install, or is there some other pod command to refresh an existing pod with a new implementation?
Look into 'app/build/generated/source/r/debug' and confirm there's an R.java being created for the architecture component. It'll be under 'android/arch/lifecycle/reactivestrams'.
I think there are 2 problems here.
Problem 1
Somehow Doppl/J2objc is of the opinion that this file should be transpiled. It could be either that 'translatePattern' matches with it, or that something in the shared code is referencing it. If you can't figure out which, please post a comment and I'll try to help (or post in slack group).
Problem 2
Regardless of why that 'R.java' is being sucked into the translate step, because of how stock J2objc is configured, the code is being generated with package folders instead of creating One Big Name. That generated file should be called 'AndroidArchLifecycleReactivestramsR.h' (and AndroidArchLifecycleReactivestramsR.m). Xcode really doesn't like package folders. That's why there's a slightly custom J2ojbc being used with Doppl, so we can have files with big names instead of folders.
In cases where you intentionally use package names that match with what J2objc considers to be "system" classes, you need to provide a header mapping file to force long names. The 'androidbase' doppl library needs to add a lot of files that are in the 'android' package, which J2objc considers "system". We override those names in the mapping file.
build.gradle
https://github.com/doppllib/core-doppl/blob/master/androidbase/build.gradle#L19
mapping file
https://github.com/doppllib/core-doppl/blob/master/androidbase/src/main/java/androidbase.mappings
I screwed up.
In my dopplConfig, I have:
translatePattern {
include '**/api/**'
include '**/arch/**'
include '**/RepositoryTest.java'
}
In this case, **/arch/** not only matches my arch package, but also the arch package from the Architecture Components.
Ordinarily, this would not matter, because the Architecture Components source code is not in my project. But, R.java gets generated, due to resources, and the translatePattern includes generated source code in addition to lovingly hand-crafted source code. So, that's where my extraneous Objective-C was coming from.
Many thanks to Kevin Galligan for his assistance with this, out on the #newbiehelp Doppl Slack channel!
I'm trying to write a plugin for 3ds max, I went through the entire sdk installation process to the letter as described in the help files.
The problem I'm facing though is intellisence complaining about an invalid macro definition
"IntelliSense: command-line error: invalid macro definition:_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES_COUNT =1"
I found the definition in project settigs -> c/c++ -> preprocessor definitions as inherited from parent or project default.
I tried disabling the inherited definitions and re-entered them, this time without the space between the name and the = and all works fine so I'm guessing its a typo on their part?
Anyway, I want to change the default project or whatever to not repeat it every time i start a new project. The project is created with a wizard which required me to copy over some files to appear and after which I had to enter the sdk path.
The files I copied are plain text with some fancy extensions and not much in them so I'm guessing the defaults are described in the sdk directory.. somewhere. Does anybody know what kind of a file I'm looking for?
EDIT: I found a file called root.vcxproj_template and it has a section for preprocessor definitions but all it contains is
<PreprocessorDefinitions>_USRDLL;%(PreprocessorDefinitions)</PreprocessorDefinitions>
and no mention of the broken one
EDIT2: in another part of the file there was a path to a property sheet (maxsdk\ProjectSettings\propertySheets\3dsmax.common.tools.settings) which included the faulty definition. I fixed it an no more complaints from VS.
_CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES_COUNT = 1 means that compiler should replace all old C run-time routines such as sprintf, strcpy, strtok with new versions such as strprintf_s, strcpy_s, strtok_s and similar. It goes in pair with following definition _CRT_SECURE_CPP_OVERLOAD_STANDARD_NAMES = 1.
More you can find here: (MSDN) https://msdn.microsoft.com/en-us/library/ms175759.aspx. However I tried to use this but without success. It says that you can use this only for statically allocated buffers like char buffer[32], but compilers was still complaining bout unsecure strcpy.
I'd like to share how I implemented a solution to a problem I had, to get some feedback and maybe learn some new feature of buildbot.
Scenario:
Create a package of a given software, and upload the package to the buildmaster into a shared folder.
The package name contains some data that are known to the build system (i.e. Makefiles) specifically the sw version. Let's assume the package name is:
myapp-1.2.3-r2435.tar.gz
Question:
How do I send to the buildslave steps the required to build up the very same package name, so that the buildslave can upload the package?
Specifically I need to know the version number (but I guess this could be any param)
Implemented (and working) solution:
The makefile, once the compilation process is completed, writes a file with the required param.
The slave uses the SetProperty() step to read the content of the file into a custom named property
Once I have the value of interest in the property (let's say APP_VERSION) I use it to build the package name with the same pattern used by the build system.
The described solution works, but I do not really like it because:
1) it's complicated, hence, I guess, fragile
2) it is not OS independent (I use "echo $VAR > file" to write the file, and "cat file" to read it and set the buildslave Property)
Is there in your opinion a better way to solve this issue?
Do you have any suggestion to make the solution OS independent? (It will not work for sure on Windows, while my package shoudl be built on Windows OS too)
I am trying to build an old version of an application which consists of VC++ projects that were written in Visual Studio 2003.
My OS is Windows 7 Enterprise (64-bit).
When I try and build the solution I get the following errors:
error C4772: #import referenced a type from a missing type library; '__missing_type__' used as a placeholder
fatal error C1084: Cannot read type library file: 'Smegui.tlb': Error loading type library/DLL.
They both complain about the following import statement:
#import "Smegui.tlb" no_implementation
This is not a case of the file path being incorrect as renaming the Smegui.tlb file causes the compiler to throw another error saying it cannot find the library.
Smegui is from another application that this one depends on. I thought perhaps I was missing a dll but there is no such thing as Smegui.dll.
All I know about .tlb files is that they are a type library and you can create them from an assembly using tlbexp.exe or regasm.exe (the later also registers the assembly with COM)
There is also an Apache Ant build script which uses a custom task to invoke devenv.com to build the projects. This is the same script that the build server originally used to build the application. It gives me the same errors when I try and run it.
The strangest thing about this is that I knew it ought to work seeing as it is all freshly checked out from subversion. I tried many different combinations of admin vs user elevation, VS vs Ant build, cleaning, release.
I have got it to build successfully about 5 times but the build seems to be non-deterministic.
If anyone can shed some light on how this tlb stuff even works or what this error might mean I would greatly appreciate it.
I found a far more reliable solution: open the tlb with oleview.exe and then close it.
Not sure what this actually does but it works every time.
I think oleview is actually one of the samples included with Visual Studio but I haven't had the time to debug it and see what it is doing.
I ran into this error because one type library was trying to load a dependent type library, which it could not find. Even though the dependent type library was in the same directory, and even though that directory was in the searchable path, the compiler would error loading the first type library, but not mention the dependent type library in the error.
To find the pseudo-missing type library, I ran Process Monitor (procman64.exe) during the compile. This showed that after the reported type library had successfully loaded, a dependent type library could not be found. It even showed all of the places that it was looking for the dependent type library, none of which were where it should have been looking (e.g.: ).
The fix was to add a <PreBuildEvent> to the project to copy the dependent .tlb file to one of the directories that was actually being searched.
<PreBuildEvent>
<Command>copy /Y ..\Lib\Interop\CWSpeechRecLib.tlb .\</Command>
</PreBuildEvent>

smegui.tlb is referencing some other tlb that the compiler can't find. If you have the .idl for smegui you might be able to figure out what the other is. I suspect the missing tlb is something that original build machine had registered but that your machine doesn't have registered.
A type library is a binary description of a set of interfaces, coclasses and enums. They're usually generated for COM components, in the case of tlbexp and regasm the tlb is created from the assembly metadata. For native COM components they are usually generated from an idl (Interface Description Language) file by the midl tool.
Edit:
I just noticed you're on x64 Windows. Are you building the project with a new version of Visual Studio? If so, are you targeting x86 or x64? If the latter, it may simply be a 32bit component that the compiler can't find (or less likely, a x64 component the x86 compiler can't find if you are targeting x86), for WOW64 the registry is virtualized for x86 vs. x64 applications.
Well I finally found out why I managed to get it to build sometimes and not others... sort of.
So long as I ran the build script with elevated administrator permissions and let that get as far as it could until that error occurred, then run the build script again as a protected administrator succeeded. Those steps must be done in that exact order with no other steps in between. If I try build in Visual Studio it does not work (although I did get it to succeed once). Probably some kind of virtualisation issue although it still doesn't quite make sense.
Well I don't need help on this any more and I know it's probably impossible to fully answer this question without knowing exactly what the build is doing. However if anyone does have any more thoughts I would happily receive them.
Cheers,
Steiny
