仍然是“错误：在'*'标记之前出现预期的'='，'，'，';'，'asm'或'__attribute__'”

Question

This is a small pure C program illustrative of the problem. The program doesn't do anything; it's a stripped-down version of a larger program that exhibits the same problem.

Here is the scenario:

Mac OS X Lion;

gcc version i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00);

Sample code:

#include <stdlib.h>
#include <stdio.h>

char huge *pbA;
char huge *pbB;

int main(int argc,char *argv[])
{
    pbA = (char huge *)farmalloc(2);
    pbB = pbA;
    *(pbB++) = 'A';
    return( 0 );
}

Compile command:

gcc -c -Wall -O -g -pipe  -D_SDL myTest.c

Errors messages:

myTest.c:4: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token
myTest.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token
myTest.c: In function ‘main’:
myTest.c:10: error: ‘pbA’ undeclared (first use in this function)
myTest.c:10: error: (Each undeclared identifier is reported only once
myTest.c:10: error: for each function it appears in.)
myTest.c:10: error: expected ‘)’ before ‘huge’
myTest.c:10: warning: implicit declaration of function ‘farmalloc’
myTest.c:11: error: ‘pbB’ undeclared (first use in this function)

So, what am I missing?

Answer 1

I'm not sure what/where huge is, but the compiler can't find it in what you've given it (ie you're missing a header probably). As for farmalloc , that looks to be in <alloc.h> . Now about using these, there is an answer on another site for huge :

Keywords like near/far/huge were once used as memory models in the old MSDOS 
days when computers had a max of 640K memory.

Any machine built in the last 15 years does not have that restriction so 
unless you have a real issue where you have to use really obsolete hardware, 
I would not spend time with segmented memory model syntax.

huge , and probably farmalloc as well, seem to be deprecated by today's standards (just like far vs near pointers). Using just char * and malloc should be all you need; no strange, old headers.
