QT5 build: CC: No such file or directory

SGaist

Based on the mkspecs available, I would try the solaris-g++ or solaris-g++-64.

DING!! Give that man a ceegar! Thank you so much.

**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.
/opt/qt5/qt5-build $

For the record, this is the command that worked:

/opt/qt5/qt5-build $ ../configure -developer-build -opensource -nomake examples -nomake tests -platform solaris-g++

I'm so happy I'm just going to let it go for now and wait til tomorrow to try the gmake :-)

I am wondering about that "remove any leftovers" comment. Is that anything in particular?

Michele31415

Well gmake ran for a long time but finally gave up. This is the tail of the tale:

Michele31415

So I gave qvncscreen.h the semicolon it was missing:

#if Q_BYTE_ORDER == Q_BIG_ENDIAN
    bool swapBytes() const ;
#endif

and tried again. Now we get:

SGaist

Just add the missing ; and go on with your build.

I don't know why it's not there both the dev and latest 5.15 branch have it.

Michele31415

@SGaist OK, I changed swapBytes to m_swapBytes (which is how it appears everywhere else) and that went away. Now:

SGaist

Which version of Qt are you building ?

I would have rather added the missing parenthesis in this case.

Michele31415

@SGaist I'm building what

git clone https://code.qt.io/qt/qt5.git

gave me two days ago. Where does it tell you what version you have? Which missing parentheses?
Should this line in qvncscreen.cpp

bool QVNCScreen::swapBytes() const

perhaps be

bool QVncScreen::swapBytes() const

because further up I see

QVncScreen::~QVncScreen()
{
    if (clientCursor)
        delete clientCursor;
}

SGaist

Ok, so you are in fact building the dev branch which is Qt 6. So is that what you want ?

I am currently wondering whether you have something that changed these files. Looking at the sources, I do not see these errors in the vnc plugin.

Michele31415

@SGaist Um, I'm building QT6?? How could that be? My build directory is called:
/opt/qt5/qt5-build $
I'm following directions from https://wiki.qt.io/Building_Qt_5_from_Git Now I'm confused.

SGaist

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.

Michele31415

@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

?

jsulm

@Michele31415 I think you missed:

$ cd qt5
$ git checkout 5.12

from https://wiki.qt.io/Building_Qt_5_from_Git

Michele31415

Drat! Can I still do that now or do I have to start all over again? Maybe rm -rf qt5-build?

SGaist

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.

Michele31415

@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?

Michele31415

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

@Michele31415 said in QT5 build: CC: No such file or directory:

That line that says "Qt will be installed into" just ends in space. Have I missed something else now?

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).

SGaist

As for the bootstrap error, are you using a multithreaded build ? I do not see the error trigger the stop.

Michele31415

@SGaist "If you used the same line as in your initial post"
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.
UPDATE:
It just doesn't seem to like qvncscreen.cpp:
