#50 compiling of vcglib fails on Debian 8

[Alois Schloegl]

Trying to compile vcglib fails with this error

I'm working on Debian 8 (Jessie) using gcc 4.9.2. I've checkout the latest version of the svn repository (-r5611) ,
and run
qmake -project
qmake -makefile
make

Do you have any hints, how to solve that ?

Kind regards,
Alois
