QT5 build: CC: No such file or directory

As I wrote before, the default branch that is checked out when cloning from git is the dev branch and that one is for Qt 6.
You have to explicitly check out the 5.15 branch if you want to build Qt 5.
The repository naming is currently in discussion.

@SGaist Sorry, I must have missed that. I just assumed that if I followed the directions on a page called "Building QT5 from Git" then I'd get QT5. I don't need any particular QT5, just something more than QT4. May I ask what command I need to issue to get 5.15? Is it
git clone https://github.com/qtproject/qt5.git --branch 5.15?

@Michele31415 I think you missed:
$ cd qt5 $ git checkout 5.12 -
Drat! Can I still do that now or do I have to start all over again? Maybe rm -rf qt5-build?
-
No problem, you can checkout at branch at any time. Just ensure that all sub modules are as well.
You definitively want to nuke the build folder.

@SGaist Yup, configure ran cleanly through this time, first try. Assuming the gmake works, I'm wondering about this bit:
Qt is now configured for building. Just run 'gmake'. Once everything is built, you must run 'gmake install'. Qt is now configured for building. Just run 'gmake'. Once everything is built, you must run 'gmake install'. Qt will be installed into Prior to reconfiguration, make sure you remove any leftovers from the previous build.That line that says "Qt will be installed into" just ends in space. Have I missed something else now?

gmake failed again but I can't find an actual error line anywhere in the output, just that "Error 2" at the very end.

If you used the same line as in your initial post, you are doing a developer build and hence it won't be installed. It's an "in place" build.
Unless you want to hack on Qt, you should drop that option as it changes some flags (I don't remember which though).
-
As for the bootstrap error, are you using a multithreaded build ? I do not see the error trigger the stop.

Arrgh, yes I did. OK, we start over again. This time:/opt/qt5/qt5-build $ ../configure -opensource -nomake examples -nomake tests -platform solaris-g++This also worked. Now starting gmake -j16 again.

frameBufferLittleEndian
You might be the first person building that plugin on a big endian system.
AFAIK, that call should be commented out with a Todo comment and the method do nothing and return false.
I'd recommend doing that so your build can continue.

I was actually wondering about that. So I've now changed that block at the end of qvncscreen.cpp to read

I had to comment this out in qvncclient.cpp (probably not a good thing to do but I don't know what this is for and I don't really need VNC in QT anyway)::

You can add a
-skip <module_to_skip>to the configure command for all modules you do not want to build.When you have such build error, you should restart the build single threaded so you get the exact point where it failed. Here it is lost somewhere in one of the threads used for the build process.

@SGaist The errors seem to be in qtserialbus and MathExtras, Are those the names I'd put in -skip? (Or is there an easy fix for these?)

The skip option is only for module names.
As for the Qt declarative issue... gcc 10 is supported on Linux so it does look a bit strange...

Looks like your machine goes too fast :-D
Try building the qtserialport module before qtserialbus
You can use "make -C qtserialport" and then go on with your build.

What I do is usually start with multithreaded and if it fails go back to single threaded, fix the issue and start again with multithreaded.
