SDSoc HLS

I encountered a problem when using SDSoc. My project can compile successfully with only software functions. However, after I specified the hardware function, there was a problem with the compilation.

The pthread.h file is in the following directory and I can find it. Please help me!3.png

Re: SDSoc HLS

I expect that it's because HLS doesn't support the standard C headers - anything that you're moving to hardware will have to be stripped of anything that relies on system calls.

Re: SDSoc HLS

Thank you for your reply:
I should write the hardware function in a single .c file, and the .c file does not contain the system call.
Do you think so?

Re: SDSoc HLS

Hi @zxbzsb 

You need to do dynamic linking of the pthread library. Navigate to C/C++ build settings->C/C++ Build-> Settings->SDS++ Linker->Miscellaneous->Linker Flags

add, 

-rpath-link=<library path> and retry

 

Best Regards,
