Failed to inline fprintf into *** (Callee is varargs)

While I'm using intel hls 21.2 to compile my *.c file, which have function "fprintf" in it, the hls compiler will report this error "Compiler Error: Failed to inline fprintf into ***(a function name in my design) (Callee is varargs) " .

I'm using Visual Studio 2017 Developer Command Prompt v15.9.42, and I have quartus 18 with hls in my PC too, can someone helps me, thanks.

PS: the same *.c file worked OK on my workmate's PC, and he has the same versions of intel hls

    Hi @zuige,

    Thank you for posting in Intel community forum and hope all is well.
    I believe you are having a windows OS on your machine, and based on the situation explained it more toward setup issues as similar .c code are working in another machine.


    Might suggest the following 1)check on the version of Visual Studio installed as only list here is supported 2)Are you colleague having the same version of quartus and VS installed? if yes probably check on the directory of the HLS and quartus are installed in same directory 3)running the init_hls.bat to ensure setup are correct.
    Hope that clarify, please do let us know if that helps.
