Trying to fix 2 errors during build for openSuse Leap 15.2

While trying to run configure command
% ./configure -prefix /home/owner/qtbase -opensource

The following messages appear at the end:

Note: Disabling X11 Accessibility Bridge: D-Bus or AT-SPI is missing.
(this is NOT true, D-Bus is alive in the openSuse Leap 15.2 OS)

WARNING: QDoc will not be compiled, probably because libclang could not be located. This means that you cannot build the Qt documentation.

Either ensure that llvm-config is in your PATH environment variable, or set LLVM_INSTALL_DIR to the location of your llvm installation.
On Linux systems, you may be able to install libclang by installing the libclang-dev or libclang-devel package, depending on your distribution.
both libclang and libclang development libraries are installed as well as llvm

I saw that under home/owner/qt-everywhere-src-5.15.2/coin/provisioning, that the folder qtci-linux-openSUSE-15.2-x86_64 is missing, the one for Leap 15.1 is there.

What can I do to fix the D-Bus and more importantly the clang library problem?

Thanks for your help.

Install the dbus development package and if you really need the qdoc stuff (for whatever reason) install llvm-clang as described in the output.

So I don't think I am missing anything. However the same error keeps reoccurring upon running the configure command.

Any ideas?

Hi,

Check the configure tests logs to see exactly how the DBus failed.

@SGaist I will do that, but due to the incredible number of compiler and loader crashes, using gcc v7, I realized that something was wrong with the gcc compiler. Hence I completely took my linux system down to the bare metal and fresh installed a brand new OS and I just completed installing gcc v10 which is not supposed to have these wierd crashes (even the loader crashed twice). I have to start fresh with the offline install again, but I am hopeful that v10 of gcc will behave in a more controlled manner. Thanks for telling me to look in the logs. I will do that when I redo this project again.

OpenSuse also provides precompile Qt5.15.2 binaries so why not use those?

@Christian-Ehrlicher I might do that, thanks. It's been a long long 2 days, as I had to reinstall openSuse Linux 3 times. My user folder was completely erased, necessitating the 3rd install from ground up, I had NOT had an opportunity to adequately save things from the backup as it was holding older data. Things are all backed up now.

After reinstalling the openSuse Leap 15.2 OS, I went back to attempting to build QT-everywhere, which compiled for hours, but crashed on a nss missing package error. This seems to have occurred with linux chromium build, when looking up the error in a search engine. I will concentrate on the nss build problem, hoping to eventually come to success.

Wish you good luck and no more reinstalls. :)

@mrjj Thanks for the wishes. I am keeping careful track of everything which occurs and documenting which steps (from which QT webpage) I am carefully following. So far I have over 30 hours in these 5 attempts to build QT5 v 5.15.2 but so far success has eluded me. I will keep trying however, but hopefully not flood the forum with the 5,518 lines of errors report and such things ;-)
