When I try to launch I get [ERROR] FATAL UNHANDLED EXCEPTION: System.ArgumentException: The requested FontFamily could not be found [GDI+ status: FontFamilyNotFound] followed by lines of what I assume are functions and memory locations where the error is thrown. Build 6671 is still working for me, so using that in the meantime. Any further information needed can be supplied, thanks in advance for any and all help with this.

It looks to me that the stack trace you get from 6670 isn't related to the font errors. Build 6671 seems to work fine for me so maybe it's an issue that was resolved in the later builds. When you say that builds newer than 6622 give a stack trace as above for you, is it the case that you've tried builds 6671 and 6839, and both are giving you the GDIPlus font error?

Rank: Newbie Groups: Registered Joined: 17/10/2018(UTC) Posts: 2 Location: DUS		I started with 6858 and got some font errors. After installing a few fonts - e.g. Andale - I got less errors, but the application still crashed. Then I tried 6839 getting the same error messages. Version 6670 seemed to work initially even though a X11 error was reported. Only after loading the above mentioned examples SMAth crashed. Sorry, I skiped testing 6671. Today I tried 6671 on Mint. The same X11 error is still there, but Newton example loads without crashing. 6858 AND 6839 on Mint No X11 error on startup, but GDI+ error <<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 6858 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Code: jro@jro19 ~/Programs/SMathMono_6858 $ mono SMathStudio_Desktop.exe - [AppDir] SpecialFunctions 1.12.6858.3232 (6 ms.) - [AppDir] HTMLFileType 1.14.6858.3232 (3 ms.) - [AppDir] ImageFileType 1.11.6858.3232 (1 ms.) - [AppDir] PictureRegion 1.10.6858.3232 (3 ms.) - [AppDir] PlotRegion 1.11.6858.3232 (4 ms.) - [AppDir] SMathFileType 1.11.6858.3232 (0 ms.) - [AppDir] StandardToolboxButtons 1.1.6858.3232 (1 ms.) - [AppDir] TextRegion 1.11.6858.3232 (1 ms.) - [AppDir] SMath Viewer Files Plugin 1.1.6858.3242 (2 ms.) - [AppDir] XMCDFileType 1.12.6858.3232 (1 ms.)

Running it from the console I do see an X11 error as well now, but as it seems to work ok despite the error then for my part I won't let it bother me too much So, there hasn't been a huge number of respondents on this issue, but of the three of us here it does seem unanimous that the new mono version has troubles. It is some small comfort to know at least I'm not alone

Installed mono and double clicked the .exe and is tries to load, then nothing. Tried in terminal in mono. Got a set of errors about missing font library. Tried again to do a scree capture and had a slightly different error. Attached screenshots. Also said: debug info from gdb: Got a SIGSEGV while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. mod: topic moved in the existing thread Edited by moderator 20 October 2018 12:25:48(UTC) \| Reason: Not specified

Is there any encouraging statement you might offer, maybe just a quick indication that you know about this issue?

My apologies, I'm still working out how things are structured around here. I see now that posting unresolved bugs for each release could really pollute the forum. That should have been obvious. Can you help me change the title of this post? With the reference to a previous build it looks like the problem is old history, but it seems this thread is to be the home of the issue. If possible, here's what I would like for the topic name: SMath for Mono non-functional on Linux, FontFamilyNotFound
