<![CDATA[Trying to make configure accepting Tslib]]>Hello!

I have been banging my head against this for a few hours now...

I built Qt 5.12.7 natively on a Pi. I have one of the cheap SPI touchscreens. I got it working with the screen (just have to hide the cursor somehow) but the touch is a bit worse.

Tslib downloaded, compiled and I got it working fine. Calibration and test application run as they should. All well there.

But I can't make configure add Tslib as it should. "ERROR: Feature 'tslib' was enabled, but the pre-condition 'libs.tslib' failed.", it says. Looking in the log:

loaded result for library config.qtbase_gui.libraries.tslib
Trying source 0 (type inline) of library tslib ...
None of [libts.so libts.a] found in [] and global paths.
=> source produced no result.
test config.qtbase_gui.libraries.tslib FAILED

I put symbolic links to the libs in the places I think they should be. I really can't make this work... Probably missed something simple.

Please let me know if you have some input.

Best regards, Jonas

None of [libts.so libts.a] found in [] and global paths.

And where is configure looking, exactly? [] looks like a missing environment variable, but which one? And "global paths", what does it use? Tried adding -R with a path to where I put them, but that didn't help.

You mean tslib-dev?

I tried installing it now, it was not installed. No difference when running configure but probably makes a difference later on.

I tried finding exactly where this test is made to see what it actually does but I cannot find where it is done. Maybe that could give a clue about missing environment variables or something?

Did you install the development package of tslib ?
