tcc version 0.9.28rc 2023-11-27 mob@0655fd9 (x86_64 Linux)
Given this straightforward file named foo.c:
#include <stdio.h>#include <string.h>int main(int argc, char *argv[]){
for (int i = 0; i < argc; ++i) printf("argv[%d]=%s", i, argv[i]);
printf("\n"); if (argc == 2 && !strcmp(argv[1], "-")) {
char buf[1024] = {}; printf("enter a line: "); if
(fgets(buf, sizeof buf, stdin)) printf("[%s]\n", buf);
else printf("fgets failed"); } return 0;}
The following command does what I would expect (it allows me to type
in a line of input):
$ tcc -run foo.c -
But if I try to read foo.c from stdin then foo.c itself is unable to
read, b.c. stdin is already closed:
$ cat foo.c | tcc -run - -
I tried duplicating fd 0 in _tcc_open() but that didn't work.
Suggestions welcome.
if (strcmp(filename, "-") == 0) { fd = dup(0), filename =
"<stdin>"; ...
Thanks - Eric
