Custom builder for a library

PerlMax

Hello everybody,

has someone an example for a custom builder for a library? I tried to create an Test-App with my perl Efl binding (pELF) (at the moment it is just an experiment whether it would be possible to write apps with enlightenment foundation libraries...)

This is my clickable file as far:

clickable_minimum_required: 8.0.0
builder: pure-qml-cmake
kill: qmlscene
dependencies_target: 
    - "libefl-all-dev"
libraries:
   pEFL:
       builder: custom
       build:
         - "perl ./Makefile.PL"
         - "make"
         - "make install"

with clickable build --libs I get the following error:

Can't open perl script "./Makefile.PL": No such file or directory
Command exited with non-zero exit status 2, see above for details. This is most likely not a problem with Clickable.

cd'ing into ./libs/pEFL (where I have the source of the perl module) doesn't work, too:

bash: line 3: cd: ./libs/pEFL: 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.

Thanks in advance for any help

Okay, I could build the module with a custom perl script. Now I have the perl module files under build/all/pEFL/install or so.

How do I get these files into the click package? And what path will these file have when installed?

Thanks,
Max

Good morning, i could compile the app for amd64 architecture but cross compiling didn't work:

/usr/bin/ld: skipping incompatible /usr/lib/aarch64-linux-gnu/libm.a when searching for -lm
collect2: error: ld returned 1 exit status
make: *** [Makefile:4178: blib/arch/auto/pEFL/pEFL.so] Error 1

Has someone a clue what's the problem here? Ist arm64 the same as aarch64?

And for armfh I get the following error:

In file included from /usr/include/features.h:485,
                 from /usr/include/arm-linux-gnueabihf/sys/types.h:25,
                 from /usr/lib/x86_64-linux-gnu/perl/5.30/CORE/perl.h:697,
                 from lib/pEFL.xs:3:

      |           ^~~~~~~~~~~~~~~~~~

Thanks in advance,

Maybe you will have better luck on the App dev Telegram channel https://t.me/UbuntuAppDevEN

and sharing your project's repo will help

I could built the lib, but starting doesn't work:

Launching app
terminate called after throwing an instance of 'std::runtime_error'
  what():  Lost our connection with the registry
-bash: line 1: 151018 Aborted                 lomiri-app-launch hellopefl.maxperl_hellopefl_1.0.0
Started: hellopefl.maxperl_hellopefl_1.0.0
ADB_COMMAND_FAILED

How can I start a app from the terminal, so that I can see error messages?

Thanks for the hint for the dev group, I will look into it the next days...

Best wishes

Running clickable logs should let you see the log messages for your app, if there are any. However, given what you've posted already, it seems you are running a bash script, which runs some other process, which has hit a SIGABRT condition.

Perl is not really a supported language for building UT applications, so we'd need to see your code (preferably in a git repository) to be able to help much further. Whatever you are running on the first line of your script is failing. If it is perl, then you might want to also check the system log on your device (/var/log/syslog) for possible apparmor DENIALs.
