Could icpx 2023.2 be used by Visual Studio 2022 for Windows APP development?

[barry-waves]

Hi,
Now, we use icx-cl in Visual Studio 2022 to compile Windows applications. However, we find there is icpx in the same folder. We also find a table for this (https://www.intel.com/content/www/us/en/docs/dpcpp-cpp-compiler/developer-guide-reference/2023-1/invoke-the-compiler.html)

Does it mean the icpx is only for Linux development?

Could icpx be used by Visual Studio 2022 for Windows APP development? (Not using CMake. Only use solution and vcxproj files.)

If icpx could be used by Visual Studio 2022 for Windows APP development, how to select it as default compiler in Visual Studio 2022?

Note: the version of icpx and icx-cl are both 2023.2

           the version of Visual Studio 2022 is 17.5.1

Thank you in advance.

Hello,

Thanks for being patient and understanding. 

>>Can Visual Studio 2022 for making Windows apps use "icpx"?

No, Visual Studio 2022 doesn’t have the option to select "icpx."

It's recommended to use "icx" as the default driver for Windows. Some specific settings for Windows only work with "icx" and not with "icpx." For instance, using the option "-Od" to turn off all optimizations works with "icx" on Windows, but it causes an error with "icpx."

"icpx" can be used for specifying options that are only for Linux, such as "O0" and "-fasynchronous-unwind-tables."

Certain flags for separating data items into their own sections are used differently for Linux and Windows:

- For Linux: "-fdata-sections"

- For Windows: "/Gw"

icx:

icx.exe /c /fdata-sections HelloWorld.cpp

icx: warning: unknown argument ignored in clang-cl: '-fdata-sections' [-Wunknown-argument]

icx.exe /c /Gw HelloWorld.cpp

icpx:

icpx.exe /c /fdata-sections HelloWorld.cpp

icpx.exe /c /Gw HelloWorld.cpp

icpx: warning: argument unused during compilation: '-G w' [-Wunused-command-line-argument]

Hi,
Thank you for the information.
Does the cl from icx-cl mean Clang or classic? Does icx mean Intel Compiler?

Hi,

>>Does the cl from icx-cl mean Clang or classic?

icx-cl is the Microsoft-compatible variant of icx and cl in icx-cl is nothing significant. It is the carry over from Microsoft command line compiler.

>>Does icx mean Intel Compiler?

Yes, icx is an Intel compiler. icx compiler is recommended for windows and icpx compiler is for linux.
