QT5 build: CC: No such file or directory

SGaist

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

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.

Michele31415

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

#if Q_BYTE_ORDER == Q_BIG_ENDIAN
bool QVncScreen::swapBytes() const
//bool QVNCScreen::swapBytes() const
{
    if (depth() != 16)
        return false;

//    if (screen())
//        return screen()->frameBufferLittleEndian();
//    return frameBufferLittleEndian();
    return false ;
}
#endif

Now we're getting

/opt/qt5/qtbase/src/plugins/platforms/vnc/qvncclient.cpp:642:9: error: ‘qvnc_screen’ was not declared in this scope
  642 |     if (qvnc_screen->swapBytes())

I'll have to see if qvnc_screen is actually declared anywhere.

Michele31415

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)::

#if Q_BYTE_ORDER == Q_BIG_ENDIAN
    //    m_swapBytes = qvnc_screen->swapBytes();
#endif

Now it's finally linking but still not happy with some qtserialbus stuff:

I'm not particularly interested in the serial bus. Can I exclude this somehow? I grepped the configure --help for "serial" but came up empty.

SGaist

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.

Michele31415

@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?)

SGaist

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...

Michele31415

What name should I give configure -skip to exclude the requirement for libQt5SerialPort.so?
Oh wait a minute, I do have that library:

/opt/qt5/qt5-build/qtserialbus/lib $ ls
cmake                     libQt5SerialBus.so        libQt5SerialBus.so.5.8.0

"-skip qtserialbus" for example.

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.

Michele31415

@SGaist That worked:

/opt/qt5/qt5-build $

I'm doing the gmake over again without -j anything. Even though I don't think -j16 is particularly ambitious, sometimes it gets ahead of itself. It just takes forever with only one CPU on the job.

SGaist

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.

Michele31415

I've started doing that too. In any case, with this:

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

we're now going much further but are not there yet.

Honestly, this error is mystifying.

SGaist

That one is just a warning. Does it error out on this warning ?

Michele31415

Hah! That joke's on me. (From now on I'll search for "error:" instead of just "error") Here's the real error:

Dunno what you're supposed to do about it though? :)

I think your error has also been reported in this forum:
Qt 5.7.1 build in Debian (MIPS) fails.

@SGaist was going to deal with that topic back in 2017 :)

Michele31415

"Dunno what you're supposed to do about it though? :)"
Well that makes two of us. In my own search, this seems to suggest it's a programming error:
https://stackoverflow.com/questions/22788026/error-lvalue-required-as-unary-operand
How sayest thou, O great Gaist?

JonB

@Michele31415
:)
Yes, it's a programming error in the code which only shows up on certain architectures. Why it has not been picked up in whatever version you are building (which is that?) I do not know.

While building qt5 in Solaris 11.4 SPARC, I get:

Not that I know about these things, but then are you "MIPS"?

SGaist

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

Not that I know about these things, but then are you "MIPS"?

Nop, he's SPARC.

As for that issue, coming from ASSIMP, it's likely something you should bring to their folks.

Sadly I do not have a big endian machine to check further what is going on there.

Michele31415

@SGaist "Sadly I do not have a big endian machine to check further what is going on there."
Would you like an account on my machine? It's a Sun T4-1 with plenty of spare CPU cycles and a fast fiber connection. Consider it my contribution to the QT project.

Michele31415

@SGaist I decided to press on, using the "scorched earth" method. Every time I hit an error I just commented it out. Turns out there were only two more places, in MathExtras.h. I now have a build that contains no instances of "error:". It ends thusly:
