Vc Build Error

[GRABNER Friedrich]

Dear All,

I want to try and vectorise my code using Vc. However first I am trying some of the examples, and I am having a little trouble.

Firstly I can easily build both the 0.7 and 0.8 branches however for the master branch I see the following error:

[ 15%] Building CXX object CMakeFiles/Vc.dir/avx_sorthelper_AVX.cpp.o

Despite using the same cmake settings. Ok I don't mind using version 0.8 however I cannot get it to compile...

Using gcc-5.2, I am trying to compile the example matrix (though the same/similar errors occur for all examples) as I have seen from investigating the archives the reccomended compilation settings are something like this:

g++ -std=c++11 -march=native -O3 -I/path/to/include -L/path/to/lib -lVc main.cpp 

The error I receive is as follows:

main.cpp:(.text+0x202): undefined reference to `Vc::RandomState'
main.cpp:(.text+0x28d): undefined reference to `Vc::RandomState'
main.cpp:(.text+0x7c2): undefined reference to `Vc::RandomState'

or 

/tmp/ccue4a62.o: In function `Vc::(anonymous namespace)::runLibraryAbiCheck::runLibraryAbiCheck()':

I have really exhaustively tried to find the issue but to no avail.

I have high hopes for being able to use Vc as it seems far easier to implement and has much better documentation than other similar tools such as boost::simd...

I look forward to hearing your response,
