Symbols not found while trying to run on Alpine Linux

[alanszlosek]

I've cloned the 4 repos, and have compiled and installed sugar (and sugar-datastore, sugar-artwork, sugar-toolkit-gtk3) on the latest Alpine Linux 3.21. I am seeing the following when I run sugar:

** (main.py:737): WARNING **: 19:25:35.422: Failed to load shared library 'libsugarext.so.0' referenced by the typelib: Error relocating /usr/local/lib/libsugarext.so.0: sugar_event_controller_reset: symbol not found

Do you have any pointers on what I should do next?

If I'm understanding the errors correctly, it seems the typelib might not reflect what's in the shared libraries, but I'm not certain.

Do you have any guidance on how I can investigate and fix?

Thank you!

Did you get any errors during compilation and installation?

The problem seems to be from sugar-toolkit-gtk3 which should have installed sugarext but doesn't seem to have.

You can also look at this dependency list to make sure you have all the needed dependencies.

[alanszlosek]

I didn't see any compliation errors, and libsugarext.so and libsugar-eventcontroller.so are building just fine. The shared libs and the symlinks are installed in /usr/local/lib.

When those shared libs are missing from /usr/local/lib I get "No such file or directory" for the shared libs. But when those libs are installed, as you can see above I'm getting "symbol not found" errors.

I'll check out the dependency list you mentioned, that's helpful! I found many of them by running autogen.sh and addressing it's complaints. :-)

Based on the errors I'm seeing, my hunch still is that the gobject introspection typelib somehow isn't matching the symbols in the shared libs correctly. But maybe I'm missing something.

[chimosky]

I'm curious, how did you compile and install sugar and it's dependencies?

The commands you ran.

Sorry for the late reply ... Here's a script that automates everything I did.

I ran this within an Alpine Linux 3.20 qemu virtual machine.

See if installing gir1.2-sugarext or the equivalent for alpine - not sure there's one - helps solve the issue.

There's nothing out of the ordinary to me, @quozl any ideas?

[quozl]

You've not done configure and make with the dependencies installed. In particular, you've done a make for each software component but left the make install until later. As a consequence, the later components won't find the earlier components, and may go into a build without them.

Instead, start with sugar-artwork, do the autogen.sh, configure, make, and make install.

Only then if that works do the same with sugar-toolkit-gtk3.

Only then if that works do the same with sugar-datastore.

Only then if that works do the same with sugar.

Also, check how the Fedora and Debian developers build the components, i.e. which order they declare the build dependencies in.
