Hi mattias,
<div>i am not quite sure on the version </div>
<div>i downloaded the tar file from <a href="https://gitorious.org/vc/vc/source/ad142ee3b7e2526cb8880cc5d8e492adfdbdd6a8:">https://gitorious.org/vc/vc/source/ad142ee3b7e2526cb8880cc5d8e492adfdbdd6a8:</a> no version numbers are mentioned there.</div>
<div>the documentation that i've build says Vc 0.99.71-dev as specified in include/vc/version.h</div>
<div>is that ok?</div>
<div><br>

Hi all,<br>
I wanted to evaluate the Vc library. Got some build errors in<br>
<br>
In file included from /Users/etijskens/Downloads/vc-vc/build/trigonometric_AVX+XOP+FMA4.cpp:20:<br>
In file included from /Users/etijskens/Downloads/vc-vc/include/Vc/Vc:22:<br>

In file included from /Users/etijskens/Downloads/vc-vc/avx/vector.h:23:<br>
/Users/etijskens/Downloads/vc-vc/avx/intrinsics.h:582:5: error: use of undeclared identifier '_mm_comlt_epu32'<br>
AVX_TO_SSE_2(comlt_epu32)<br>
^<br>
(Similar errors from the three succeeding lines as well)<br>
I checked the CMake files for any variables that could solve the problem. As suggested in the documentation (portability issues/compiler flags) I added<br>
CMAKE_CXX_FLAGS -march=corei7-avx -mavx<br>
<br>
The errors go away when i #undef VC_IMPL_XOP just before /Users/etijskens/Downloads/vc-vc/avx/intrinsics.h:581<br>
<br>
As far as i know XOP is for AMD cpus and should not be activated in my build. CMake detects<br>
TARGET_ARCHITECTURE=ivy-bridge<br>
<br>
i am compiling on a machine with Intel? Core? i7-3615QM Processor and Mac OS X (maverick) using the clang 5.0 compiler.<br>
I am not sure that<br>
a) the problem is correctly solved by undefining VC_IMPL_XOP<br>
b) there is not a more elegant solution<br>
Any help is very much appreciated.<br>

I never can remember the mapping of Apples clang version to the actual clang <br>
version. The latest released version of clang is 3.4 <br>
(http://llvm.org/releases/download.html). I think clang --version should print <br>
the actual version somewhere.<br>
<br>
In any case, you are right that your system doesn't need the XOP stuff. The <br>
XOP code is compiled because the libVc library is supposed to work for any <br>
target system. Thus you can build build applications for different hosts on <br>
your machine without having to recompile libVc. But if your compiler doesn't <br>
do XOP anyway then this feature is moot. So disabling XOP support is the right <br>
way to go.<br>
<br>
We have two options to fix this:<br>
a) quick: call set(Vc_XOP_INTRINSICS_BROKEN true) in cmake/VcMacros.cmake for <br>
depending on the clang version on Apple systems<br>
b) more generic: make the -mxop compiler flag check more thorough. Right now <br>
it only tests whether the compiler barfs with the flag. But it doesn't check <br>
that with -mxop it also supports the XOP intrinsics. There's a similar check <br>
in cmake/AddCompilerFlag.cmake for -mfma already. Should be easy to copy and <br>
adjust.<br>
<br>
Cheers,<br>

I have a feeling Khouri and I fixed this before. What Vc branch did you check <br>
out? Could you try 0.8 please? 0.8 is mostly 0.7 but with a bit more freedom <br>
for MacOS and Windows fixes.<br>
<br>
Cheers,<br>
