QT5 build: CC: No such file or directory
-
Ah ha! I set QMAKE_CC and QMAKE_CXX in qtbase/mkspecs/solaris-cc/qmake.conf and that got me going again. Configure went much further this time but now it's stopped with this:
/opt/qt5/qtbase/src/corelib/global/qrandom.cpp: In function ‘void fallback_fill(quint32*, qsizetype)’: /opt/qt5/qtbase/src/corelib/global/qrandom.cpp:297:18: error: ‘getauxval’ was not declared in this scope 297 | ulong base = getauxval(AT_BASE);Apparently getauxval is some linux thing. There's a discussion around this here: http://lists.opencsw.org/pipermail/users/2019-January/010420.html so unless anyone has a better suggestion, I'll pursue that.
-
I decided the simplest thing was to just remove getauxval since it seemed to be optional anyway. Now we've made more progress. configure is almost finished but ends like this:
...........(long list of files redacted) ...Done. Info: creating super cache file /opt/qt5/qtbase/.qmake.super Info: creating cache file /opt/qt5/qtbase/.qmake.cache ERROR: Invalid value 'test' supplied to command line option 'nomake'. /opt/qt5/qtbase $ -
Isn't it "-nomake tests" ?
-
Good catch - I missed the last character when I copied the command out of the instructions. But now I'm getting the "You cannot make a shadow build from a source tree containing a previous build.
Cannot proceed." message.
Is my only option to delete the entire qt5 directory and start over? I'm not seeing a "confclean" option. -
I'd go with make distclean but I am not sure, I haven't done any in tree build since over a decade. Always out of source, it allows you to keep your sources clean and start from scratch more easily.
-
I'm just following the recipe here: https://wiki.qt.io/Building_Qt_5_from_Git
$ mkdir qt5-build $ cd qt5-build $ ..\\qt5\configure -developer-build -opensource -nomake examples -nomake testsIn any event distclean did not work for me.
/opt/qt5/qtbase $ gmake distclean gmake: *** No rule to make target 'distclean'. Stop. /opt/qt5/qtbase $Update: Oh dear - I just noticed I somehow ended up in qtbase rather than qt5-build. Why don't I just start over.
-
Well, since you are getting started, it's not a bad idea to just build qtbase. You can then build the rest later on.
-
I just started over from scratch. This time it almost finished:
..Done. Info: creating stash file /opt/qt5/qt5-build/.qmake.stash Info: creating super cache file /opt/qt5/qt5-build/.qmake.super Running configuration tests...

I thought I had fixed that with the following change to qtbase/mkspecs/mkspec.conf:
#QMAKE_CXX = CC QMAKE_CXX = /usr/gcc/10/bin/g++Technically this was more of an end-run than a fix. I still don't know where CC is being set. So there must be another instance somewhere I can't find.
-
Silly question but did you check your environment variables ?
Note that you seem to set only QMAKE_CXX, did you also set the other one ?
-
Yes, I also said this in qtbase/mkspecs/mkspec.conf
#QMAKE_COMPILER = sun_cc QMAKE_COMPILER = gccEnv vars are:
/opt/qt5/qt5-build $ echo $CC /usr/gcc/10/bin/gcc /opt/qt5/qt5-build $ echo $CXX /usr/gcc/10/bin/g++ /opt/qt5/qt5-build $ which gcc /usr/gcc/10/bin/gcc /opt/qt5/qt5-build $ gcc --version gcc (GCC) 10.2.0 Copyright (C) 2020 Free Software Foundation, Inc.

-
What about the QMAKE_CC variable ?
-
That's set too:
# QMAKE_COMPILER = sun_cc QMAKE_COMPILER = gcc QMAKE_CC = gcc -
I just realized, did you try to specific the platform in your configure options ?
-
Uh, I guess not. What file would that be?
-
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.

Cross-toolkit compatibility disabled. **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?

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

So I gave qvncscreen.h the semicolon it was missing:
#if Q_BYTE_ORDER == Q_BIG_ENDIAN bool swapBytes() const ; #endifand tried again. Now we get:

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.

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