Intel c++ compiler error with pybind11 using -std=c++17

[Soprana__Arthur]

Hello,

I am getting a compile error when using the Intel c++ compiler (ICC - 19.0.0.046 20180317) when compiling a simple code, basically importing pybind11 with the option -std=c++17. The error log is very large, but starts as follows

The command line call was

icpc -std=c++17 test.cpp -I/pybind11/include/path -I/python/include/path

However, if I change the option to -std=c++14 or c++11, it works fine. g++ also compiles with no problems when using the c++17 option. It seems like a compiler bug. The code used is presented below.

// test.cpp
#include <pybind11/pybind11.h>

int main(){
    return 0;
}

Does anyone have any idea of what this might be?

Best regards,

Arthur Besen Soprana

I think this issue has been fixed. Please wait for 19.0 beta update. it should be available soon. Please check back on the beta thread. It should be updated when the beta update is available.

Can you please create a preprocess file for us? 

$icpc test.cpp -E -std=c++17-I/home/soprano/work/pybind11/include -I/home/soprano/miniconda3/include/python3.6m

Thanks,

Viet

Sure, here it goes (see attached file).

[pfahler__lukas]

Any updates on this one?

[Viet_H_Intel]

Have you tried 19.0 Update 5?

[Soprana__Arthur]

No sorry. My intel license has expired and therefore I am not able to check if it works on this version.

The error still persists.

[Viet_H_Intel]

For some reasons, I couldn't be able to download your preprocessed file. Can you upload it again.

[Soprana__Arthur]

Here it goes

[Viet_H_Intel]

Thanks for the preprocessed file. I've reported to our Developer. Internal tracking number is "CMPLRIL0-32248"
