Support for exceptions

[mottosso]

Hi @crosire,

This isn't a bug report, I just wanted to document that exceptions don't appear to be supported by blink (?)

I'm initially had issues with VS2019 but luckily found #30 which got me half-way there, except the default "Console Application" preset in VS comes with exceptions enabled, which prompts the following error.

Unresolved external symbol '?uncaught_exception@std@@YA_NXZ'.

Full output

Initially I suspected that maybe blink needs to be built with exceptions in order to support it, but it already was. Turning off C++ exceptions for the console application solved it.

Exceptions themselves should not be a problem. But VC++ 2019 (in contrast to 2017) isn't working particularly well out of the box with blink, because of the reason noted in #30. You'll likely have to set up a compiler command-line matching your project here and rebuild blink:

blink/source/blink.cpp

Line 386 in fc5811a

cmdline = "cl.exe "

It all boils down to 2019. Can't make any promises, but I'll see if there's anything I could do to resolve this. Blink has been fantastic so far, despite the minor issues so thanks for that!
