Elmer build error on 10.11.6

[othreed]

Hi,
I started with a fresh brew install on my el Capitan OSX and ran into an Error about qt4.
I ran:

brew install elmer.rb --with-elmergui --HEAD

I got the message while installing dependencies:
==> Installing dependencies for elmer: qt5

But later i get this this error about wrong QT version

==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.

How do I resolve the problem with QT4 Not found?

[juhanikataja]

Can you install qt4 using homebrew at all anymore? If not, then it means that ElmerGUI needs to be migrated to use Qt5.

[othreed]

I saw that homebrew created three directories:
/usr/local/opt/qt5/
/usr/local/opt/qt/ <- this should be 4.x
/usr/local/opt/qwt/

Any suggestions?

[othreed]

I cleaned everything in homebrew and started again.

brew install elmer --HEAD --with-elmergui
Updating Homebrew...
==> Installing elmer from elmercsc/elmerfem
==> Installing dependencies for elmercsc/elmerfem/elmer: openssl, libevent, open-mpi, cmake, veclibfort, scalapack, hypre, mumps, qt, libpng, freetype, ftgl, freeimage, gl2ps, tbb, oce, boost, fontconfig, szip, hdf5, jpeg, libtiff, vtk, qt5, qwt

so I wonder why qt5 is neccesary

[Spranky63]

Same problem here.

OS X 10.11.6
gcc 6.3.0_1
brew version 1.1.6
XCode 8.2.1

Changed my local elmer.rb compiler lines to

ENV["CC"] = "/usr/local/Cellar/gcc/6.3.0_1/bin/gcc-6"
ENV["CXX"] = "/usr/local/Cellar/gcc/6.3.0_1/bin/g++-6"

$brew install elmer --HEAD seemed to compile okay, output was:

But $brew reinstall elmer --with-elmergui --HEAD gave following errors related to qt:

Hoping someone can find away to get the Elmergui to install.

Observation

ElmerGUI depends on qwt in elmer.rb, and the qwt install depends on qt5 see:

$ brew deps qtw

[Spranky63]

Got a step further, but bare in mind I am not a software engineer or terminal expert.

I commented out a line in the findQT4.cmake file in

/usr/local/Cellar/cmake/3.7.1/share/cmake/Modules/FindQt4.cmake

There are some lines:

set(QT4_INSTALLED_VERSION_TOO_OLD FALSE)

#set(_QT4_QMAKE_NAMES qmake qmake4 qmake-qt4 qmake-mac) **Commented Out by Me**
set(_QT4_QMAKE_NAMES qmake4 qmake-qt4 qmake-mac) **Added by me**
_qt4_find_qmake("${_QT4_QMAKE_NAMES}" QT_QMAKE_EXECUTABLE QTVERSION)

if (QT_QMAKE_EXECUTABLE AND
  QTVERSION VERSION_GREATER 3 AND QTVERSION VERSION_LESS 5)

I effectively commented out the qmake option to prevent it loading the one from qt5.

I then renamed the qmake file in /usr/local/Cellar/qt/4.8.7_2/bin to qmake4.

I then did $brew link --force qt

Now doing $brew reinstall elmer --with-elmergui --HEAD

gets past the qt5 problem described above.

Unfortunately still does not 100% build. Gets to 75%. Here is the make log file found under Users/myname/Library/Logs/Homebrew/elmer

02cmake.txt

Again, if anyone can help it would be appreciated. I can confirm Elmersolver is working from the command line as I tried an example.

The Elmer wiki:

http://www.elmerfem.org/elmerwiki/index.php?title=Compiling_ElmerGUI_from_source_with_optional_components

suggests to try commenting out sections of elmerGUI.pri in order to solver compiling problems. I tried modifying the

/Users/mayname/Library/Caches/Homebrew/elmer--git/ElmerGUI

elmerGUI.pri file but this just keeps getting over written by the one in the GIT repository when I do $brew reinstall elmer --with-elmergui --HEAD. Unfortunately I am not a Homebrew expert and so do not know how to modify my local tap elmer.rb file so that the files in a local repository with a modified elmerGUI.pri are used.

I think there might be away to download the elmerfem 8.2 archive, modify it, store it locally and change something in the local tap elmer.rb code lines:

desc "Elmer finite element solver"
 homepage "http://elmerfem.org"

 head "https://github.com/ElmerCSC/elmerfem.git", :branch => "devel"

 stable do
  url "https://github.com/ElmerCSC/elmerfem/archive/release-8.2.tar.gz"
  sha256 "ed4c87895c76003dd81faa464b6d0f38225d43e584f75290df21df629d0a4ecc"
 end

but I do not know how. Help!

Seems as though the Mac Elmer community might be very small and there is not much interest, or they do not use the elmerGUI, judging by how little info and help there is available.

[othreed]

Hi,
I ask a MAC programmer on Freelancer to do the native compilation and provide clear build instructions for us Darwin *NIX Users. Because I could not get the brew install working.

So hopefully He will get it working natively.

I do not know when he will finish it or if he succeeds but I will publish the result in the Elmer Forum and also here :)

I gave up myself because I have not enough knowledge and my time is limited to do the debugging.

:)

[Spranky63]

Great Idea othreed.

I managed to comment out some options in ElmerGUI.pri but it did not help. I also tried to install the Elmer 8.0 Archive and got to 79%. Both installs give the fatal error

/tmp/elmer-20170106-53903-izw3ce/ElmerGUI/Application/vtkpost/vtkpost.cpp:67:24: fatal error: QVTKWidget.h: No such file or directory
 #include <QVTKWidget.h>

If you google "Elmer QVTKWidget.h" there are some old posts on the web referring to similar problems i.e.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=614952.

It would be great if someone could get it working.
