Unable to build CMake project from QtCreator

Platform Development
#1

Hey,

I’m unable to build any CMake project from QtCreator, for example the official cmakesample. Configurating CMake project in QtCreator succeeds:

But then the build button stays gray:

And build configuration says that a CMake configuration is missing, what ever is means (for example CMakeCache.txt exists there):
grafik

Build for i486 fails with an other error, because of missing Ninja which is used by default (can be fixed with changing the Generator in CMake parameters, but after that the problem from above stays):

-- Configuring incomplete, errors occurred!
See also "/home/richard/src/build-cmakesample-SailfishOS_4_3_0_12_i486_in_sailfish_sdk_build_engine-Debug/CMakeFiles/CMakeOutput.log".
CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

A reinstallation did not fixed the problem. QMake projects work as expected. Building with sfdk also works.

Does anyone have an idea how to solve the problem?

[Release notes] Sailfish SDK 3.9
#2

Could you please try whether clearing the configuration would help? For that to do stop the IDE first, then back-up and remove ~/.config/SailfishSDK.

#3

Unfortunately this does not change anything.

Side note: I had to deactivate snapshots (sfdk config --global no-snapshot=force) again after deleting because it fails for me (cp: failed to clone '/srv/mer/targets/SailfishOS-4.3.0.12-armv7hl.default/.sdk-manage.conf' from '/srv/mer/targets/SailfishOS-4.3.0.12-armv7hl/.sdk-manage.conf': Invalid cross-device link and analogue for many more files when snapshots are active). Maybe it is related.

#4

This is very likely related. One consequence of the cp failure is that the IDE is not getting all the required data and disabling snapshots does not fix that part.

I am thinking whether there is anything special about your Docker installation that could cause the failure? Which storage driver is your Docker using? And what is the filesystem below that? See Docker storage drivers | Docker Documentation. (I am using overlay2 on btrfs.)

If you find no way to fix it, then you could disable the problematic code. Enter the build engine with sfdk engine exec and edit /usr/bin/sdk-manage there. Under the sudo_sync_trees function, locate the line where can_reflink is set and comment out the value assigned to it:

    local can_reflink= #$(is_reflink_possible "$src" "$dst" && echo 1)

Then do Build > Clean Project under the IDE (or sfdk build-requires reset under a build directory) to see the effect.

I would be very thankful if you could find out what is causing the cp to fail.

#5

I also use Btrfs with Overlay2 for Docker.

The first insight is that copying new files via --reflink=always works (see is_reflink_possible). But not copying files that already existed when the container was started.

Maybe the read-only layer and the top read-write layer are on different filesystems? It looks like it is a problem with my Docker setup and not related to the SDK. If I find a solution I will add it here.

#6

After I changed the storage driver to btrfs and reinstalled the SDK, it now works.

Maybe the check in is_reflink_possible can be adjusted to use an existing file instead of a new file.

#7

Great! Yes, is_reflink_possible definitely deserves a fix.

#8

This has been fixed in Sailfish SDK 3.9, which was released to Early Access users today.
