Re: [deal.II] Warning messages about text-based stub files not syncing with library files when compiling on Mac.

2019-01-30 Thread Jean-Paul Pelteret 
Dear Zachary,

I googled this problem and it seems that, dependent on what version of Xcode 
and MacOS you’re running, there might be one of two solutions. Here’s a similar 
post on the Apple forums that outlines the two possibilities 
. The first possible solution 
(which may only work for older versions of Xcode) to remove and reinstall the 
command line tools. The second would be that the link line generated by CMake 
is causing the issue.

This is the selected solution from the Apple forum post 
:
> You have to link directly to the library and not rely on -isysroot or 
> -frameworks in your makefile. you need to link like -L /path/to/lib 
> libstuff.dylib
and something that we’d likely have to implement on our side.

Can you please provide the deal.II configuration logs (detailed.log, 
summary.log), tell us more about your system setup (MacOS and Xcode version), 
and also provide the verbose output when building one of the tutorial programs 
(you can get this using “make VERBOSE=1”). I hope that this might be sufficient 
information to help solve this issue.

Best,
Jean-Paul

[deal.II] Warning messages about text-based stub files not syncing with library files when compiling on Mac.

2019-01-30 Thread Zachary Hardy 
When I compile the examples, I receive about 12 warning messages about 
linking stating that the text-based stub files and library files are not in 
sync, all from within `/System/Library/Framework/Accelerate.framework.' 
Everything ends up working in the end, but I can't seem to remedy this 
issue to get rid of the warning messages. Has anyone seen this before, and 
if so, what steps can be taken to resolve this issue? Below is an example 
of the warning messages.

ld: warning: text-based stub file 
/System/Library/Frameworks//Accelerate.framework/Accelerate.tbd and library 
file /System/Library/Frameworks//Accelerate.framework/Accelerate are out of 
sync. Falling back to library file for linking.

Sorry, Wolfgang. I already uninstalled MVSC from my computer and deleted

Re: [deal.II] Change in the behavior of Boundary Id interpretation from GMSH 2 to GMSH 4?

2019-01-30 Thread Bruno Blais 

Dear Daniel,
Sorry I dropped the ball on this one.
I checked out the patch and tested it on two of my full cases and 
everything works well.
No differences between a GMSH ASCII 2 and GMSH ASCII 4, whereas before I 
had the previous issue.

>From my point of view this fixes everything.

Thank you very much!

Ester -- yes, not surprising. MS Visual Studio is, as far as compilers 
go, a pretty crappy one and we've often found that if we don't regularly 
test with it, all sorts of code that works just fine across all other 
compilers is just broken on Visual Studio. You'll likely save yourself 
some pain by going with the Linux subsystem.

That said, if you happened to still have your VS around, would you mind 
opening a github issue and copy-paste the error messages you get into 
it? It might still be useful to see if they are easy to fix...

Best
  W.

[deal.II] Re: Problems installing dealii on Windows with VS2017

2019-01-30 Thread Ester Comellas 
Daniel,

I switched to the deal.ii code version you mention (#7520) and, indeed, it 
compiles and I'm able to run steps 1 to 3 (haven't tried beyond that). 
However, I'm having trouble building my program in Visual Studio. It seems 
that it cannot find the right libraries because I get a whole bunch of 
errors related to TrilinosWrappers.

Also, I thought you might want to know that before using version #7520 I 
tried the latest one at the time (#7652) and I got tons of C2131 
(expression did not evaluate to a constant) and C2975 (invalid template 
argument for..) errors when trying to compile deal.ii. 

In the end, I've given up on MVSC and I installed the Windows Subsystem for 
Linux. This is a great feature, thanks for your advice!  My code is running 
smoothly now.

Regards,
Ester
