Compilation problem on Fedora 24

ycollet · June 25, 2016, 3:14pm

I am currently compiling ardour and Carla on Fedora 24. They use gcc 6.1.1 and flac 1.3.1.
Here is the error message I’ve got:

I think you might want to report this to the Carla or Ardour devs. I’m not sure which JUCE version they are using.

The problem can still happen with the current version of JUCE.

I replaced

static inline long int lround(double x) {
return (long)(x + copysign (0.5, x));
}

by
static inline long int jlround(double x) {

And replaced all the occurences of lround in this file and the problem was fixed. No more conflict with std::lround.
