QT5 build: CC: No such file or directory

Don't do that kind of things as root, you might break stuff ;-)

One thing I would do is to just build and install qtbase so you have a working base to go further.

I thought gmake install always had to be done as root. In any case, it works even less as ordinary user in qtbase:

/opt/qt5/qt5-build/qtbase $ gmake install
cd src/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtbase/src/src.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ -skip qtserialbus ) && gmake -f Makefile install
gmake[1]: Entering directory '/opt/qt5/qt5-build/qtbase/src'
cd tools/bootstrap/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtbase/src/tools/bootstrap/bootstrap.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ -skip qtserialbus ) && gmake -f Makefile install
gmake[2]: Entering directory '/opt/qt5/qt5-build/qtbase/src/tools/bootstrap'

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

Only when installing into system directories only writable by root.

SGaist

Sorry, I managed to miss a part of my answer. You should put the sources somewhere in your standard user home folder and do the build there. Then when it's done successfully you can install it and then do it as root if you want it in a system folder. Otherwise, if it's just for your user, you can install it somewhere in your user home folder.

I guess I don't understand. I'm the only user. I always use /opt for big projects like QT or QEMU. The last thing I did was:

/opt/qt5/qt5-build/qtbase $ gmake -j16  > build.log 2>&1

and that completed with no errors. So do I now have a working Qt5 in /opt/Qt5 that I can call from other builds? (QT5 is a prerequisite for the OpenSCAD 3D modeler).
The "Building Qt5 from Git" web page says that after doing gmake you should do gmake install. Can I just go ahead and use Qt without doing the install? How do I tell if it's working?

SGaist

Unless you created a developer build you have to call make install in order to have everything in the right place. Since you have already configured everything else you can go on in each required sub directory and call make/make install.

If the modules are note configured, you can use the classic qmake/make/make install.

Michele31415

OK, so I say:

/opt/qt5/qt5-build/qtbase $ gmake
...
(tail follows)
gmake[1]: Leaving directory '/opt/qt5/qt5-build/qtbase/qmake'
cd doc/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtbase/doc/doc.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ -skip qtserialbus ) && gmake -f Makefile 
gmake[1]: Entering directory '/opt/qt5/qt5-build/qtbase/doc'
gmake[1]: Nothing to be done for 'first'.
gmake[1]: Leaving directory '/opt/qt5/qt5-build/qtbase/doc'

and then

/opt/qt5/qt5-build/qtbase $ gmake install
cd src/ && ( test -e Makefile || /opt/qt5/qt5-build/qtbase/bin/qmake -o Makefile /opt/qt5/qtbase/src/src.pro -qtconf /opt/qt5/qt5-build/qtbase/bin/qt.conf -- -opensource -nomake examples -nomake tests -platform solaris-g++ -skip qtserialbus ) && gmake -f Makefile install

I don't understand why files in /etc are being accessed.

Do you have the same issue if you build Qt in a standard user home folder ?

Michele31415

@SGaist No, I have not tried building it from my directory in /export/home/. I'm not really sure why that would give a different result. I'm the only user on the machine.

Michele31415

OK, I believe I have now successfully installed Qt5 in Solaris 11.4 SPARC. Referring to the above failed gmake install, there were three different things going on.

/lib/libQt5Bootstrap.a not found. So I did

ln -s /opt/qt5/qt5-build/qtbase/lib/libQt5Bootstrap.a /lib/libQt5Bootstrap.a

/usr/bin/pod2man was a symbolic link pointing to itself (that's weird). So in /usr/bin I said

rm pod2man
ln -s /usr/perl5/5.26/bin/pod2man pod2man

All the "cycles found" errors (not shown above) were because gmake install was using /usr/bin/install instead of /opt/csw/bin/install. So I said

cd /opt/csw/bin
ln -s ginstall install

After those changes,

# /opt/qt5/qt5-build/gmake install

worked fine.
