Re: FreeCAD in a very old machine

I have debug my run, and apparently one of the dependencies, xerces-c, is compiled with sse2 support by default in that version of lubuntu. I am building it from source to disable sse2 now... Out of curiosity, how is this controlled? Compiler optimization flags? for this case, there is a --disable-...

Re: FreeCAD in a very old machine

Hi Abdullah, I do not know the answer but I think it is also important to tell what your installed OS is Hi! Yes, definitely. I can install in the computer whatever linux distribution. The priority is that it runs FC. Currently it is running Lubuntu 17.04. I have debug my run, and apparently one of...

FreeCAD in a very old machine

Does anybody know if FreeCAD v.17 can run in a AMD K7 (without SSE2) from early 2000?

I installed freecad-daily and I get illegal instruction...

Re: PD NEXT: Mapping change and support

Unfortunately, catching OCC exceptions will make freecad App depend on OCC. Currently it doesn't, all OCC stuff is delegated to Part module. As far as I understand, FreeCAD can be built without OCC if Path and all dependent modules are disabled. PS. And stupid C++ exception handling doesn't offer a...

Re: PD NEXT: Mapping change and support

I would welcome more user input. What does a user want here? I like the exclamation mark. The more verbose/specific error thrown to report view the better. As a user I'm not sure what is a bug or user error w/0.17. I would also like to standardize the exception error messages, so that it is possibl...

Re: PD NEXT: Mapping change and support

I think you should catch all OCC exceptions and re-throw them as Base::RuntimeError, then. (wmayer seems to usually recommend against throwing base::exception, and to pick a more specific type) Well, at first I was trying to make the lowest amount of changes, as I am not familiar with PD NEXT and I...

Re: PD NEXT: Mapping change and support

More to it. DeepSOIC was right that there was code for raising an error, that exception catching that I commented out, will make it propagate the error. So at the end the question is whether we can just comment out that exception catching: https://github.com/abdullahtahiriyo/FreeCAD_sf_master/commit...

Re: PD NEXT: Mapping change and support

I am trying to figure the best mechanism for setting an error flag from attach extension. This is the recompute stack: #0 Part::AttachExtension::extensionExecute() #1 App::DocumentObject::execute() #2 Part::Feature::execute() #3 App::DocumentObject::recompute() #4 Part::Feature::recompute() #5 App::...

Re: PD NEXT: Mapping change and support

In any case, I deem unacceptable to silently ignore a wrong support. FreeCAD should do something. Exclamation mark in the tree view suggesting feature has a wrong support? It used to do that in past. It looks like it's broken. I will try to reestablish the exclamation mark and throw an error to the...

Yes. Switch to Part WB. Select the sketch, and invoke Part->Attachment from the menu.


BTW, Thanks!! I got concentrated in the second part of your answer. It is absolutely counterintuitive. We shall do something about it.
