Not buildable if having qt4 and qt5

[afrowerks]

I had installed qt-sdk first since I wanted to be able to try the toolchain out, which is for 5.0.1, but even after installing qt4, I get this error below. I would think that if you have a requirement towards a specific version of a tool you shouldn't have to uninstall or tweak something just to satisfy installation of the dcputoolchain. (Following are the make error and installed qt packages respectively.)

(FYI, Trying to use qmake -set didn't work due to a bug leading to multiple internal variables of the same name.)

For the first of those errors, you need to make sure you clone submodules.

But for Qt, it seems as though Qt5 is the default on your system... not knowing anything about compatibility between Qt versions, maybe try telling the toolchain to use Qt5?

Or temporarily setting Qt4 as the default?

if i remember correctly, qt is only needed for the pre-alpha gui. there
should be an option to cmake without the gui ( and thus without the qt
dependencies)

Thanks for the quick responses,

I think I will manage the qt stuff, haven't really had time today to pursue
further. I ran into a bug/feature in qmake in the process...

My point was that as a developer, time is precious, and you'd not want to
spend it on initial troubleshooting.
The guide I followed was this one --
https://github.com/DCPUTeam/DCPUToolchain/blob/master/README.md -- and
maybe I should have followed some other description. I didn't see anything
about any submodules. Typically you'd just add some option --recursive to
the git command if everything is ok in the repo.

I first stumbled upon this page --
http://dcputoolcha.in/docs/tutorial/10cco/gettingtools.html -- which
promises also to get you started, so there's some effort needed in getting
more juice into the pages that meet newcomers like me. Maybe that this
particular tutorial/guide focus on Windows users where things maybe are
pre-packaged?!

BR, Andreas

try commenting this line of the main CMakeLists.txt:244
http://github.com/DCPUTeam/DCPUToolchain/blob/master/CMakeLists.txt#L244

this should remove all qt dependencies.
dtide isn't done anyway, and i'm surprised it is enabled in the main branch

this project has been dying out, with almost no activity for > half a year.
but any feedback is still appreciated.

cheers
