Excellent.
Could you please set output mode = Use shared libs, by default? So one shouldn`t change settings each time after "fresh" install.

Default value was always set to "Shared libs", and I'm not doing intall, just running "ide" from an appropriate "out" subdirectory.

The problem seems to happen because very first time I ran TheIDE link_mode was serialized as static in ide.cfg, and I was trying to fix GCC.bm ...

For not to spam with a new topic, I`ll post next Linux problem here. Due to the Ubuntu requirements I switched to ALT Linux Lite distribution which uses Xfce window manager. It uses RPM packages type.

With next step I installed U++7007.1 RPM. Then installed all the dependencies manually (as no program suggested installing dependencies itself). TheIDE ran smoothly with no errors.

By default output mode in release build was once again switched to Static, and I switched it to Shared libs. After that I had no errors with compiling and linking. But pressing Ctrl-F5 does nothing. Newly linked application simply does nothing (cannot start?). The same is with attempt to run application from file manager - it doesn`t start without any error messages.
The same was with non-GUI application which I also tried to compile and run.

The question to Linux developers: what could it be? How may I solve this problem or at least how can I find where problem is?

Try to run from console "$strace <your application>". You will see kernel calls (you won't see libc calls like dlopen).
If that doesn't clarify the problem try to run "$LD_DEBUG=libs <your application>" (in case of bash ...). This command traces run-time linker.

If the problem still remains unresolved, post output of those commands here.

The window manager overrides Ctrl-F5 shortcut (it is used for workspace switching). You can try to disable tis shortcut in window manager settings.

Logs are OK. The strangest thing is that it started smoothly after reboot. What a strange thing this Linux...
Let`s consider this problem solved. Thank you everyone.
