SCO Xenix (286) build error

[Randrianasulu]

Basically in tok_io.c compiler barfs at
lines 220 and 564 - "error 1: newline in constant

"

varargs also give me another error, but other object files seems to be OK

[Randrianasulu]

ah, modern gcc 11.2.0 output those as warnings too:

token.h:42:41: предупреждение: assignment to «int» from «char *» makes integer from pointer without a cast [-Wint-conversion]
   42 | #define put_ch(c)       putchar(last_ch = c)
      |                                         ^
tok_io.c:220:13: замечание: в расширении макроса «put_ch»
  220 |             put_ch(" ");
      |             ^~~~~~

tok_io.c: В функции «fix_line_control»:
tok_io.c:564:17: предупреждение: assignment to «int» from «char *» makes integer from pointer without a cast [-Wint-conversion]
  564 |         last_ch = "\n";
      |                 ^

I initially thought error was due to `` instead of "" but it was not the case ...

If you change a character constant 'c' to a string pointer "string" you'll get warnings from almost any compiler, because that is not what you want and very likely it won't work.

[Randrianasulu]

:( yeah, I already changed ot back. Also, it seems second error screen is irrelevant bevause make does not compile this file :)

Can I preprocess this file with gcc's cpp and pass result to Xenix's cc ? (random idea)

[udo-munk]

Sure, you can try that, might help to locate the problem because the compiler error about a newline in the character constant is nonsense.
