Hi Aleksander,
thanks for previous response. I've built DBUS and added to my device and
warning disappeared. Unfortunately, I have another issue, I cannot run
ModemManager, because there are undefined symbols during plugin load e.g.:

There are much more, I've attached file.
I built ModemManager on one machine for my device - cross compilation. Build is
successful. I've checked compile log and there are no errors only few warnings,
which looks not critical for me.
Line 664: libtool: warning: remember to run 'libtool --finish /lib64'
Line 773: libtool: warning: '../libmm-glib/libmm-glib.la' has not been

/lib64/ModemManager'
Line 1167: libtool: warning: '../libmm-glib/libmm-glib.la' has not been

I built latest ModemManager 1.18.2 with Autotools (make) with following
dependencies:
Glib - 2.68.2
libmbim - 1.26.0
libqmi - 1.30.2
libgudev - 236
dbus - 1.12.20
systemd - 248
zlib - 1.2.5
Mentioned dependencies have been cross compiled as well before they are
referenced during modem manager build. I am not sure it will help when I
provide part of Makefile.

Then make and make install is called afterwards. Compilation is successful. I
checked issues related to undefined symbols in ModemManager git web sites but I
did not find any solution for me. One proposal says to check/change prefix,
libdir to /usr/. I tried more prefixes, even without prefix, but it still says
undefined symbol for plugins.
Call example: # LD_LIBRARY_PATH=/usr/local/lib /usr/local/sbin/ModemManager
--debug - did not solve issue
I've checked plugins .so files with nm command and ldd. Ldd does not contain
any not found reference. Missing symbol is marked as undefined in plugin.so:
# nm build/ModemManager/target/lib64/ModemManager/libmm-shared-option.so | grep
mm_base_sim_export
U mm_base_sim_export
I found that this symbol is defined in ModemManager binary:
# nm build/ModemManager/target/sbin/ModemManager | grep mm_base_sim_export
00000000004500c0 T mm_base_sim_export
When I checked code this function is defined in:
ModemManager-1.18.2\src\mm-base-sim.c
ModemManager-1.18.2\src\mm-base-sim.h
ldd /usr/local/lib/ModemManager/libmm-shared-option.so
linux-vdso.so.1 (0x00007fff5d98f000)
libc.so.6 => /lib/libc.so.6 (0x00007f2a1419e000)
/lib64/ld-linux-x86-64.so.2 (0x00007f2a1475b000)
I also tried to set to build static libraries, but for that case ModemManager
did not show any warning and said that no plugins have been found in
/lib64/ModemManager/
Seems it is linking issue and I have not found root cause. Do you have any
idea/hint which can help and I can move forward?
Another question. I've started to use meson instead of autotools for build, not
successful build yet. It looks that it uses only pkgconfig, are there some
variables which can override includes and libs without using pkgconfig - I
tried -Dc_args and -D c_link_args but it did not find dependencies at all -
failed in setup in beginning? With pkgconfig dependencies was found.
By the way what is correct release folder, I found 2?
https://www.freedesktop.org/software/ModemManager/ - only tar.xz files, latest
1.18.2 archive does not contain meson.build
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/archive/1.18.2/ModemManager-1.18.2.tar.gz
- includes meson.build
Thank you for any answer. Have a nice day
Best regards
