Something probably went wrong with automatic builds of developer versions of Rawtherapee in Github. I tried to run RT_dev_5.8-2330 and RT_dev_5.8-2334 (both extracted from zip packages, in Windows 10 x64) and twice get an error (in Polish):
“Nie można kontynuować wykonywania kodu, ponieważ nie znaleziono obiektu libssp-0.dll. Ponowne zainstalowanie programu może rozwiązać ten problem.”
Which in English is - according to Google Translate:
“The code cannot continue because the libssp-0.dll object was not found. Reinstalling the program may fix this problem.”
I checked twice, and there were no libssp-0.dll in RT folder, actually.
But this is still quite a mystery, because previous RT_dev_2313 (also extracted from downloaded zip package) runs perfectly, is stable, yet also does not contain libssp-0.dll.
I found that libssp-0.dll could be downloaded alone from internet, but even when I did so and saved it in RT folder it did not help - just an error were different - but RT still did not start.
I am not a programmer, but maybe something in automatic build system should be corrected?
