No success building on Mint 19

[luis]

Hello,

I'm running linux mint 19.0 and had a number of issues while trying to build openEMS,
lib vtk5 was not available so I just replaced it by vtk6... hope that is ok.

had some trouble also with gcc ver 7 as it said could not find CXX compiler but later this
I added CXX=gcc to the environment but all stayed the same. Not sure what else I have tried and later the
error disappeared... (kind of irrelevant but I post this bit of info just for the sake of completeness of all my steps)

Then it builds up to certain point and I presume it fails at the linker... end of the log file is pasted below.
Any help ?

( btw, I've also trying to install from the binaries from the dac922 ppa (https://launchpad.net/~dac922/+archive/ubuntu/openems)
but the ppa does not support 'bionic' and that is what latest Ubunto and Mint does on the latest versions... so no luck here either)

Thanks.
Luis.

Replying to my own post

I could not make any sense out of the errors that I was getting so I undo/remove as most as I could
and repeated the build attempt from start (installing manually cmake and vtk6)

All built without problem.

because of my messy attempts I did before it is not easy for me to report now what was wrong/missing
to build for mint 19.0. Soon I will have a chance to build on a fresh mint 19.0 and will take notes and will let you
all know.

Luis.

Hi,

I think there were some issues on Ubuntu 18.04 (which Mint 19 is based on right?).
If I find the time I will setup a VM with Ubuntu and give it a try myself.
At some point I dream from having an openEMS as flatpak which should make life easier?

regards
Thorsten

Dear Thorsten,

Yes please. It would be a dream if you could provide a flatpak with openEMS .

Currently, the compilation implies downloading more than 1 GB of dependencies that I will not download because I would not like that my production environment breaks due to incompatibilities. So, flatpak would be a very nice solution.

Nowadays, the windows versions seems the only easy installation environment.

Thanks for openEMS,
Fernando

Hello,

It ended up quite simple. (tested successfully on two fresh/clean installed machines).

for bionic based like Mint19 / Ubuntu 18.04... the lib install should be as follows.

sudo apt-get install build-essential git cmake libhdf5-dev libvtk6-dev libboost-all-dev libcgal-dev libtinyxml-dev libqt4-dev libvtk6-qt-dev

I would say that a simple update of the install web page adding this alternative for the "bionic" distros would do just fine.
(but surely a flathub or appimage is quite appealing...)

I noticed also that the lib install (as above) followed by the paste of a built image into a folder
works also like a charm... kind of a poor-man's appimage

Luis.
p.s. Thorsten, thanks A LOT for this fantastic package.

I can't install on mint 19. I have depedencies as luis. I tried also vtk7 - it didn't help.

/home/michal/build/openEMS-Project/AppCSXCAD/main.cpp:20:10: fatal error: QVTKOpenGLWidget.h: No such file or directory
#include <QVTKOpenGLWidget.h>
^~~~~~~~~~~~~~~~~~~~
compilation terminated.

[thorsten]

That is an error due to a false include for the vtk8 updates. I just pushed an untested fix. Update the git repositories and try again please

It works Thanks!
