I am working on the os161 project. I create a file which include the array.h provide in src/kern/include. When I compile, I had the error like this: ./../include/array.h:85: error: expected '=', ',', ';', 'asm' or 'attribute' before 'unsigned' ../../include/array.h:91: error: expected '=', ',', ';', 'asm' or 'attribute' before 'void'

the code is like:

#ifndef ARRAYINLINE
#define ARRAYINLINE INLINE
#endif

ARRAYINLINE unsigned    --------------line 85 error
array_num(const struct array *a)
{
    return a->num;
}

ARRAYINLINE void *     --------------line 91 error
array_get(const struct array *a, unsigned index)
{
    ARRAYASSERT(index < a->num);
    return a->v[index];
}

and this kind of error happened at every line has something like INLINE or ARRAYINLINE. This array.h file is provided and I made no change to it. Really cannot figure out why.

  • Error says that the compiler is not able to understand what `INLINE` is. Maybe `#define ARRAYINLINE INLINE` is `define ARRAYINLINE inline` requesting the compiler to `inline` the functions? If not, is `INLINE` defined while compiling? – another.anon.coward Mar 26 '12 at 09:22

    Try to get program text after preprocessor and show it. E.g. for gcc it's option "-E". The most probable variant is no definition of INLINE or strange one. – Netch Mar 26 '12 at 09:30
  • Can you add the const struct array please? And a bit more code as well. What is your command to compile? – Patapoom Mar 26 '12 at 09:22

I'm working on os161, too. INLINE is not defined, try using #define ARRAYINLINE inline instead.

[EDIT]

I checked my os161 revision. I found this line before the #define ARRAYINLINE INLINE

#define INLINE extern inline

So please check if your array.h also contains this line (115 in my case)

I'm working on OS161 as well, this error could be generated if you have a random character outside of your function. Example:

#include <...>
...
e //<-this random character that could have been mistyped.

sys_fork(...){
...
}
