Linux Issues

[jmf]

Hi,

I'm just getting started with Ultra App Kit from steam and I'm having a number of issue on Linux that I didn't notice right away, due to not using certain commands.  I've tested and troubleshooted these issue in Manjaro, Ubuntu, and openSuse, with the same results on all three platforms. 

1.  In the new project dialog the ... ellipse folder picker button does nothing. 

2.  Application menus don't seem to work, straight copy pasted from the examples on the website(aside from minor changes where environment detection was done for plugin loading).  When I click one of the menu items, e.g.  "File", the menu appears near the center of the window detached from the menu bar, and clicking a menu item causes the program to hang.  GDB doesn't show any output when this happens for a few seconds, before displaying "Warning: MapNotify is taking a long time to be received. This may cause window errors."  I've tried breaking on any handled exception but I don't get any output. "(gdb) catch throw" aside from one instance in the "Advance Application Interface" tutorial, where I found that I needed to install "curl" and "zenity", but again failed when accessing the application menu.   ctrl+c quitting the app and getting a backtrace, "(gdb) bt" doesn't show anything useful, because it's just related to the WaitEvent() in the while loop.

3.  the compiler flags in the settings.json file for Linux should be:

"makeArgs": ["CONFIGNAME=Debug","PRODUCT_SUFFIX=_d","CONFIGFLAGS=\"-ggdb\""]"

 

4.  The Image Viewer tutorial seems to be missing a plugin,  "FreeImage.so",  (I can't determine where I'm supposed to be able to find plugins if there is a place), but that's just a guess, assuming it's not just necessary for windows (the dll version is there).  The debug info is of no use.

All the output shown here is from a fresh & clean install of ubuntu 20.04.4 with all listed prerequisites installed + gdb, libc6 sources (for gdb), curl, and zenity.

The output shown here is the same that I was getting on manjaro and opensuse.  For this ubuntu test, I generated a new project from the launcher.

 

Any info or guidance I can get would be greatly appreciated.

Thank You.
