Hello everyone,

I'm having some problems to build Seg3D version 2.1.4 on my machine with Archlinux and also in another one running Fedora 18. In both cases I get the same error.

The cmake step is OK. However, during the compilation (make) I get the following error:

Building Seg3D returned an error

Either the code failed to build properly or the testing programs failed to complete without every single test program passing the test.

Any ideas of how to solve/fix this? What is missing? I have installed all the required software. I have Qt 4.8.x and also Qt 5. What is wrong?

Thanks in advance.

Best regards,
