honggfuzz does not support file as input?

[fr0zenrain]

my host is WSL2,I found file input seems not work.thanks!

#include "stdio.h"

int main(int argc, char* argv[]){
        char buf[1024]={0};
        FILE* fp = fopen(argv[1],"rb");
        if(fp == 0) return -1
        fread(buf,1,1024,fp);
        fclose(fp);
        return 0;
}

honggfuzz -i seed -x -- ./test FILE [2022-10-19T16:20:38+0800][E][32377] cmdlineVerify():243 You must specify 'FILE' if the -s (stdin fuzzing) or --persistent options are not set

my target is complex, so i don't want change my target to stdin as input.

Are you using ___FILE___, with three underscores (_)?

$ cat a.c 
#include "stdio.h"

int main(int argc, char* argv[]){
        char buf[1024]={0};
        FILE* fp = fopen(argv[1],"rb");
        if(fp == 0) return -1;
        fread(buf,1,1024,fp);
        fclose(fp);
        return 0;
}

$ honggfuzz -i corpus/ -x -- ./a ___FILE___
