Cura 15.x doesn't use libArcus.

Are you trying to build Cura 15.x or Cura 2.x?

15.06 doesn't use libArcus

[chenjianyyzz]

I try to build Cura 15.06.03, and I have a check, the LibArcus is needed by Cura 15.06.03, and I check the CMakeList.txt & ubuntu-15.04-build-script.sh, LibArcus is also used inside.

Why would you want to build cura 15.06? It's riddled with bugs.

[fieldOfView]

15.06 doesn't use libArcus

It did! 15.04 didn't.

[BagelOrb]

Ah Yes, I was confused with 15.04.6

[BagelOrb]

In that case: don't try to build cura 15.6!

You can try to build Cura 15.06, but you must be fairly certain that you use the correct versions for everything then, including cura-build itself.

The most common linker errors are solved by making sure that ld is called with the correct libraries to link against. CMake has a LDFLAGS variable. If you add the parameter --libs <path to your libArcus> it might find it properly.
