That's how it should be, then.

Vc has trouble building it's test suite. But to build the library and headers, you can do without the tests. Building the tests can be switched off by telling cmake not to build them.

To be on the safe side, please start afresh: remove the botched build directory (rm -r build), create a new one (mkdir build), cd into it. modify the call to cmake to read:

cmake -DCMAKE_CXX_COMPILER=clang++ -DBUILD_TESTING=0 ..

Then issue 'make' and 'sudo make install'. This should run through without errors and install Vc 1.4 to /usr/local. You should now - finally - be able to run pv's makefile in pv's root directory. Please do a 'git pull' on my repo before building pv, there are some recent additions.

Let me know how it goes.
