Linux Support

[dev-inigmas]

I keep seeing download/build instructions for Windows/Mac. Does this work on Linux?

I tried building this on Ubuntu 16.04 today. I added a PPA with qt5.10 because that seems needed.. But the build fails..

@dlpatri Yes, ideally, it should work on all the platforms which can run the latest Qt. @popey Thanks for reporting, I will look into it when my Ubuntu VM ready.

[huxingyi]

Hi, I have tested on Ubuntu 16.04.4 LTS, and updated the build steps in docs https://dust3d.readthedocs.io/en/latest/builds.html Please check the Ubuntu section of the docs, and download the latest code(Have slightly changed Dust3D.pro file).

[dev-inigmas]

I'm running Ubuntu 18.04. Got to the point where I run qmake then make. This is what I get:

dlpatri@Bebop:~/thirdParty/dust3d$ qmake -qt=5 -v -makefile
QMake version 3.1
Using Qt version 5.9.5 in /usr/lib/x86_64-linux-gnu
dlpatri@Bebop:~/thirdParty/dust3d$ make
make: *** No targets specified and no makefile found.  Stop.

[huxingyi]

Hi, David, I saw the folder name "thirdParty", is your file structure like this?

~/thirdParty/dust3d/dust3d.pro

If not, please run theqmake -qt=5 -v -makefile in the path where you can find the dust3d.pro.

A difference between what I did (as opposed to what the instructions tell me to do) is that I did not build my own CGAL. But that's because I'm running Ubuntu 18.04; which seems to have the required version in its repositories:

$ sudo apt list libcgal-dev
Listing... Done
libcgal-dev/bionic,now 4.11-2build1 amd64 [installed]

[huxingyi]

Sorry, my bad. there is a mistake in the docs. Should be qmake -qt=5 -makefile

[dev-inigmas]

I assumed -v was for verbose.... I'm guessing it was for "version"?

[dev-inigmas]

Alright; so that worked. I got Dust3d up and going. The UI is a bit small; but at least it seems to be running. Thanks :)

[huxingyi]

You are welcome, there is a commit coming to fix a windows crash and the UI issues. I am testing it, will commit when ready.

[huxingyi]

I am closing this now, thanks for help. the UI small problem has been fixed in the latest commit.

[dev-inigmas]

Verified that https://dust3d.readthedocs.io/en/latest/builds.html no longer has the -v option in qmake. I agree with the closing.

Thanks again.
