Building 5.9 from git

[kshegunov]

Hi,
I can't seem to build 5.9 from sources, I'm following the wiki guide and configuring like this:

./configure -debug -opensource -nomake examples -nomake tests -confirm-license -prefix /home/nye/Programming/C++/qt/5.9

I see nothing unusual while qmake's being built, and the configure summary looks okay:

The only (qmake) error I could see in the output is something with syncqt but I have no idea what that is to begin with.
Any advice is highly appreciated.

@kshegunov I just reconfigured and run it again. It still working.

662 mkdir ../delete-me
663 #./configure -debug -opensource -nomake examples -nomake tests -confirm-license -prefix /home/nye/Programming/C++/qt/5.9
664 pwd
665 ./configure -debug -opensource -nomake examples -nomake tests -confirm-license -prefix /nodes/misc/storages/third-party-install/build/delete-me
666 make -j8 module-qtbase

Maybe you should just scratch it, make sure you have no weird config variables around and start over. Sometimes the universe just switches a fatal bit.

If you have ccache activated it will just takes a few minutes...

Before that, I run:
sudo apt-get install '^libxcb.*-dev' libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev
sudo apt-get install build-essential perl python git

System is Ubuntu 17.04

I did not use -prefix in the configure command.

Since syncqt.pl is in:
merlin@headquarter:/nodes/misc/storages/third-party-install/build/qt5$ find . -iname "syncqt"
./qtbase/bin/syncqt.pl

You may try and copy it to the location where your system is trying to find it.

@c64zottel said in Building 5.9 from git:
Thanks for your effort.

I did not that -prefix in the configure command.

Please do if you could and let me know. From what I can tell the configure script sets the path for that script wrongly (I don't have it in the prefix path, nor should I - I have it in the source tree).

You may try and copy it to the location where your system is trying to find it.

This is a no-go, I have 3 other Qt builds, including a developer's build, and I'm not about to copy files around, much less into system locations without being absolutely sure I won't break something.

EDIT:
I think I misunderstood you if you meant me to copy the script into the prefix dir, I'll try that.

EDIT 2:
Copying the script helps only partially. I don't get that error anymore, but instead the build fails later with:

@kshegunov I just reconfigured and run it again. It still working.

Did that before posting. I can definitely confirm this is a configure script problem, in-source build (without -prefix) works perfectly fine.

I just reconfigured and run it again. It still working.

Did you clean before rerunning configure?

$> git submodule foreach --recursive "git clean -dfx" && git clean -dfx

[c64zottel]

@kshegunov I did now, still runs through. Did you install the dependencies as stated on the guide?

Another thing you can try:
Make your build options equal to the ones I listed above. There are some minor differences. (I doubt that this would help, but who knows)

What's your system? Ubuntu 17.04?

@c64zottel said in Building 5.9 from git:

Yes, of course. As I said in-source build works fine.

What's your system? Ubuntu 17.04?

Debian testing
Kernel is 4.9.0
g++ version is 6.3.0

[kshegunov]

Apparently a stray (hidden) cache file or folder. Everything builds normally now. Sorry for the noise.
