CssParser causing build errors on older Linux version

[David Healey]

I'm trying to build HISE on LinuxMint 19 (Ubuntu 18.04) and I'm getting some errors relating to the CssParser. I don't get these on my main system running the latest version of Debian.

[Christoph Hart]

hmm, that's weird. Does it help if you change the line 159 to

SourceType fullArea = Context<SourceType>::getDefaultSource();

It looks like the compiler on this system chokes on the syntax of constexpr function calls. Which GCC version is installed there?

[David Healey]

@Christoph-Hart Yeah that change solved the issue. It's using GCC 7.5, this is the oldest version I've been able to compile HISE on.
