svrng compilation fails

[SGold21]

I am trying to compile a project on Linux with oneAPI using Eclipse.

The include to svrng.h fails because:

/opt/intel/oneapi/compiler/2021.1.1/linux/bin/../compiler/include/svrng.h:350:28: error: expected parameter declarator
typedef struct _ALIGN_ { __m256i r1; __m256i r2; } svrng_uint16_t;
^
/opt/intel/oneapi/compiler/2021.1.1/linux/bin/../compiler/include/svrng.h:338:51: note: expanded from macro '_ALIGN_'
#define _ALIGN_ __declspec(align(32))

What might be the problem?

Thank you

[Alex_Y_Intel]

Can you please supply reproducer?

[SGold21]

just include "svrng.h" 

I included it (just #include "svrng.h" line)  to a working project - and it fails.

[Alex_Y_Intel]

Can you please tell me which compiler you tried to use? Is it a DPC++ or C++ application?

[SGold21]

It's a pure C++ application that compiles fine with the OneAPI compiler up to the point where I include "svrng.h"

[Alex_Y_Intel]

Can you please provide a screen shot of project settings/compiler settings in Eclipse, and a copy of your verbose build log?

[SGold21]

These are the settings I change:

[Alex_Y_Intel · Accepted solution]

From the pictures and log you've supplied, you're using Intel oneAPI DPC++ compiler. Since you mentioned that it's a pure C++ application, you should use icx compiler instead and this problem should go away.

[SGold21]

I have the option of Intel Compiler Classic.

Is it the one you refer to?

If not,  which one is it?

Thanks.

[Alex_Y_Intel]

An Intel Classic compiler should be able to compile your application. You can also use new Intel oneAPI C++ compiler. Please refer to this article:

https://software.intel.com/content/www/us/en/develop/documentation/oneapi-dpcpp-cpp-compiler-dev-guide-and-reference/top/compiler-setup/using-eclipse/adding-the-compiler-to-eclipse.html

Adding the Compiler to Eclipse*

This step is needed only if you are manually installing the Intel® oneAPI DPC++/C++ Compiler plug-in for Eclipse*.

To add the Intel oneAPI DPC++/C++ Compiler product extension to your Eclipse configuration:

1. Start Eclipse.
2. Select Help > Install New Software.
3. Next to the Work with field, click the Add button. The Add Repository dialog box opens.
4. Click the Archive button and browse to the <install_dir>/compiler/<version>/linux/ide_support directory. Select the .zip file that starts with com.intel.compiler for C++ or com.intel.dpcpp.compiler for DPC++, then click OK.
5. Select Intel® Software Development ToolsIntel® C++ Compiler for C++ or Intel® oneAPI DPC++ CompilerIntel® oneAPI DPC++ Compiler for DPC++, then click OK.
6. Follow the installation instructions.
7. When asked if you want to restart Eclipse, select Yes.

When Eclipse restarts, you can create and work with CDT projects that use the Intel oneAPI DPC++/C++ Compiler.

I am going to close this case for now as a solution has been provided.
