When compiling qt for ubuntu 16.04 I am having an error in the object 'build/backtrace.o'

To compile I'm simply doing

Quote

qmake denarius-qt.pro
make

Any ideas about the possible mistake?'

Thanks and salute

You need libevent-dev installed now due to Tor integration:

Code:

sudo apt-get install libevent-dev

Installed and tried to compile with both command line and QT creator. I always found this error:

Try changing in the denarius-qt.pro file the line that has QMAKE_CFLAGS from -std=c99 to -std=gnu99
