      I've built dependencies and app to armhf, to try debugging on my old BQ Aquaris E5. clickable gdb gives me illegal instruction:

      $ clickable gdb --arch armhf

        All I can say so far is that I can reproduce the issue with Pure Maps, but not with the CMake app template from Clickable.

          You can set a break point at main and step through it. This way you will find that it exits because the parser fails to parse command line arguments. it returns at line 112:

          109	  // command line
          110	  CmdLineParser *parser = CmdLineParser::instance();
          111	  if (!parser->parse(app->arguments()))
          112	    return 0;

            @talkless Could you please try to add libc6-dbg to the dependencies_target before running the gdb command?

              Commenting out the CmdLineParser lines allows you to debug Pure Maps btw.

                @jonius Have you actually seen these source lines within gdb? Because there's no symbols for me:

                Reading symbols from /home/vincas/code/puremaps/pure-maps.git/build/aarch64-linux-gnu/app/install/lib/aarch64-linux-gnu/bin/pure-maps...(no debugging symbols found)...done.
                

                Also, commenting out command line parsing did nothing, and even adding qFatal() did not make app to die in normal run. As if clickable install --arch arm64 just installs some old release build...

                Also, clickable install takes 3 minutes to upload app into my Volla Phone X...

                Also, clickable launch logs does not show any output, no "logs"...

                So far, much pain...

                  It seems I forgot to add --arch arm64 together with --debug, so I was building.. probably desktop version all the time.

                  Yes, removing CmdLineParser lines allows to keep debugging further.

                  Does that mean that clickable gdb launches application incorrectly, without some expected arguments that where provided via .desktop file (or whatever) for example?

                    @talkless You can run the gdbserver command with --verbose to see the command line parameters. I suspected the --desktop_file_hint which is necessary for the display server. Adding that one as an allowed parameter to the parser doesn't help though. So no idea, to be honest.

                      Oh boy, I've updated clickable (it suggested that there's latest version):

                      pip3 install --user --upgrade clickable-ut
                      

                      Updated images:

                      clickable update-images
                      

                      Rebuilt everything:

                      clickable script prepare-deps
                      clickable build --libs --arch arm64
                      clickable build --arch arm64 --debug
                      

                      But it fails to install picotts on final app build step:

                      Installing libraries
                        /home/vincas/code/puremaps/pure-maps.git/build/aarch64-linux-gnu/s2geometry/install/lib/libs2.so
                      Installing binaries
                        /home/vincas/code/puremaps/pure-maps.git/build/aarch64-linux-gnu/mimic/install/bin/mimic
                      find: '/home/vincas/code/puremaps/pure-maps.git/build/aarch64-linux-gnu/picotts/install/usr/bin/': No such file or directory
                      Command exited with non-zero exit status 1, see above for details. This is most likely not a problem with Clickable.
                      

                      Not sure why it install pico if it's full build:

                      $ file clickable.yaml 
                      clickable.yaml: symbolic link to packaging/click/full-build.yaml

                        Are you sure you have picotts built? It makes sense for it to be in the full build, because it offers more languages than mimic.

                        I just found another bug in the latest version of Clickable related to installing QML modules. Until it is released, you find the fix here: https://gitlab.com/clickable/clickable/-/merge_requests/553

                            @talkless looks like it is correct. How does tree build/aarch64-linux-gnu/picotts/install look like?

                              @jonius It's empty:

                              $ tree build/aarch64-linux-gnu/picotts/install
                              build/aarch64-linux-gnu/picotts/install
                              
                              0 directories, 0 files
                              

                              Other sibling directories (like mimic) are NOT empty.

                              Permissions of picotts are right.

                              picotts directory of x86_64-linux-gnu and arm-linux-gnueabihf are NOT empty too.

                                @talkless Can you try building it again with verbose output (clickable build --libs picotts --arch arm64 --verbose)?

                                    The problem is make: 'install' is up to date. when this isn't true. You can avoid it by always building picotts clean. Or by touching the binary as in https://github.com/rinigus/pure-maps/pull/646. Just be aware that the master branch of Pure Maps is already configured to build for UT 20.04.

                                        @talkless you might need to build clean once, looks like an outdated build cache.

                                            @talkless the latest version of Pure Maps is UT 20.04 only. If you run 16.04, you can go back to Pure Maps 3.1.1 which is still made for 16.04.
