[QGIS-Developer] Problems compiling QGIS 3.0: no matching function for call to QgsLayerTreeLayer::connect

[Hernán De Angelis]

Thanks for the pointer, Chris. Indeed:

~> gcc --version
gcc (SUSE Linux) 4.8.5

I will chack again in two months with the new version (openSUSE 15). For
now I will live with QGIS 2.18.17 just fine.

Best,

H.
