Missing symbols on Windows when using queue properties

SYCL development
1

Hi,

there seems to be symbols (yet again) missing from the ComputeCpp libraries on Windows using ComputeCpp-CE 1.1.1 and 1.1.2. The following simple program results in linker errors, but compiles fine on Linux.

#include <CL/sycl.hpp>
int main()
{
    cl::sycl::queue q{ cl::sycl::device{}, cl::sycl::property::queue::enable_profiling {} };
}

Results in

How are you creating the project? If we use the templates to generate a project, copy in the source and build it works fine, but maybe you are creating it on the command line?

I am using FindComputeCpp.cmake and it happens with both the cutting edge VS 16 2019 (MSVC 19.20) and with the supported VS 15 2017 (MSVC 19.16). For the sake of simplicity and pedantry, this is how it plays out on the command line with MSVC 19.16:

How are the compilers not invoked the way they are intended? I’d be glad to patch FindComputeCpp.cmake and send a PR if need be.

We think it’s something to do with this toolchain file that you are using and the way this is setting up the build arguments:

This is the standard build argument set

<CommandLineTemplate>"[ComputeCppRootDir]\bin\compute++.exe" -D_SIZE_T_DEFINED -Wno-ignored-attributes -fdiagnostics-format=msvc -sycl -O2 -nobuiltininc [DeviceAdditionalIncludeDirectories] [DeviceOutputFileName] -c [Inputs] [DeviceAdditionalOptions]</CommandLineTemplate>

I may be wrong here, but how are the arguments to compute++ relevant here? No code gen is supposed to happen inside compute++ in relation to the command queue construction, it is just a template machinery that forwards the properties after type check to the underlyling OpenCL runtime. Linker errors and symbols missing originating from cl::sycl::queue CTOR invocation should have nothing to do with compute++ flags.

Am I misunderstanding something from the compilation model?

The way I see from the linker error is that ComputeCpp is using a non-header-only implementation for the queue_properties class and would require STL internals to be instantiated. The ComputeCpp extension to Visual Studio would very much like to use the v140 toolset. (I just gave the code a spin on Dániels machine, who also doesn’t have v140 installed. After retartgeting the solution to v141, he gets the same linker errors.) My guess is that Codeplay only tests releases using v140 (in VS2015) which is becoming highly outdated. VS 2017 (v141) and VS 2019 (v142) are binary compatible with VS 2015 and most applications do work. However, in this case, something seems to have gone wrong, some internals of the queue_properties class is referring to implementation functions that no longer exist.

MSVC having just recently reached C++14 conformance, using libraries like Boost::Hana et al. require pretty much latest v142 toolset. v142 supposedly being link compatible with all the way back to v140, it would be nice if ComputeCpp could play along.

We’ve now been able to reproduce it and it is indeed to do with using v141. I’m just talking with the team to find out more.

In order to resolve this we will need to produce separate binaries for v141/142. I’ll update when we have information about this.

Any updates on this?

May I add, the other solution is to use a header-only approach to implement cl::sycl::property_list{}. I’m not sure how much IP can be there. It’s a tricky class, but by no means is it black magic.

This will be resolved in the next release v1.1.5. There has been a slight delay in getting this out unfortunately.

1.1.5 is available to download. Apologies for the delay. Can you let me know if this doesn’t resolve your issue?

It resolved the issue, thanks.
