configure -skip options being ignored?

While_e

I may be misunderstanding the point of the "-skip [module]" arguments for the configuration step of compiling Qt from source. I would expect it would not attempt to build or install this in any way.

Qt source branch 5.7
Ubuntu 16.04

Given this configuration sting:

./configure \
-device linux-beagleboard-g++ \
-device-option CROSS_COMPILE=/opt/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- \
-sysroot /mnt/rootfs \

-skip qt3d \
-skip qtcharts \
-skip qtscript \
-skip qttranslations \
-skip qtgamepad \
-skip qtwebchannel \
-skip qtandroidextras \
-v

I get this ouput:

However, when I check the Makefile, I can clearly see many references to things like qtwayland, qtgamepad, etc:

So am I missing something? As stated at the start, I would expect "-skip" to exclude things like wayland, gamepad, webkit, multimedia ??

They are excluded from compilation, don't worry (unless there was some bug with that on Qt 5.7... I strongly recommend using a newer version).

If you want to be 110% sure, you can remove these modules' directories from your hard drive. Qt configuration script handles that nicely.

Thank you for the info. I didn't even think of removing the modules manually palm-to-forehead.

By your statement "I strongly recommend using a newer version", did you mean of Qt in general?

Yes. Qt 5.12 is the newest LTS release, and it contains a ton of performance optimizations, bug fixes and security fixes when compared to 5.7.

Excellent. Was attempting small incremental steps to avoid any oversights on my part during the config/make process.

I'm only at the config stage of 5.12, and I already love the additional output of env variables.. lovely.

Thanks for the input.
