Qt building from sources - xcb dependencies

[SGaist]

That is the thing: it was not built due to missing development packages of the dependencies listed as missing that you posted earlier.

[MasterQ]

I know, that's what I already said.

I followed that list

Qt for X11 Requirements

and made a checkmark on every listet item. Nevertheless, configure is claiming about missing xcb components and a built program is not starting.

I also got no helpful reply from Opensuses community.

I am now working on switching to Wayland and to skip X11. With Wayland there are no issues so far.

@Christian-Ehrlicher Already wrote that libs are missing - did you address that?
Here:

-- [QtBase] Could NOT find XCB_EWMH (missing: XCB_EWMH_LIBRARY XCB_EWMH_INCLUDE_DIR) (found version "")
-- [QtBase] Could NOT find XCB_ICCCM (missing: XCB_ICCCM_LIBRARY XCB_ICCCM_INCLUDE_DIR) (found version "")
-- [QtBase] Could NOT find XCB_KEYSYMS (missing: XCB_KEYSYMS_LIBRARY XCB_KEYSYMS_INCLUDE_DIR) (found version "")
-- [QtBase] Could NOT find XCB_XEVIE (missing: XCB_XEVIE_LIBRARY) (found version "")
-- [QtBase] Could NOT find XCB_XPRINT (missing: XCB_XPRINT_LIBRARY) (found version "")

Yes. After post #2 of this thread I checked everything again and installed devel packages as long as they were available.

I now have reinstalled/changed whole OS. After already spending too much time on that issue, a complete new install yesterday was much faster and easier. The journey is still not at its end but for now it is looking promissing.

Maybe today or tomorrow I will see if Qt configures and compiles.

But did you also build and install the XCB plug-in afterwards?

[MasterQ]

Yes, of course. .. I tried at least and failed.

I am now running a fresh OS and it seems the xcb issues are gone. But others arise. Configure says

joachim:~/Qt$ grep "NOT find" configure.log
-- [QtBase] Could NOT find Slog2 (missing: Slog2_INCLUDE_DIR Slog2_LIBRARY) 
-- [QtBase] Could NOT find GSSAPI (missing: GSSAPI_LIBRARIES GSSAPI_INCLUDE_DIRS) 
-- [QtBase] Could NOT find EGL (missing: HAVE_EGL) (found version "1.5")
joachim:~/Qt$ 

All dependencies could be solved except of the mentioned above. At the moment I can not identify corresponding libs.

for pattern slog2 I get no hit
for pattern gssapi I get several hits, like
libglobus-gssapi-assist-devel
libglobus-gssapi-error-devel
...

for pattern egl I get
gegl
glgrib-egl

Any idea how the missing libs are called?

The System now is an Ubuntu 2410.

Well, if everything you need is enabled you can ignore these missing parts.

[MasterQ]

ignoring the missing dependencies is difficult since configure stopps.

-- [QtBase] Could NOT find EGL (missing: HAVE_EGL) (found version "1.5")
-- Configuring incomplete, errors occurred!

GSSAPI could now be identified with libkrb5-dev (1.21.3-3)

FindEGL.cmake is looking for EGL/egl.h which can be found in libegl-dev and in package emscripten. Even if libegl-devel is installed, it is not found.

FindSlog2.cmake is looking for /sys/slog2.h which is not found in any package.

To which Qt parts do EGL and Slog2 refere to? I then can decide if I can ignore or skip that modules.

To which Qt parts do EGL

QtBase, you can see that in the configure output ([QtBase]).
Not sure about slog.

After installing missing dependencies you should start from scratch:

• Delete build folder
• Create new build folder
• Run cmake

[MasterQ]

Hi,

last update!

After a break due to broken hardware I have started from scratch and now all is running fine.

It seems that I previoulsy had used (by accident) an outdated compiler, gcc-7 instead of gcc-14.
