i have come across a bit of code that isn't compiling properly, and was wondering if it is just written wrong. The file that it is in is a C program, not a C++, so if any one knows if its wrong and can tell me how to fix it please do:

uint64_t al_ffblk_get_size(struct al_ffblk *info)
{
   ASSERT(info);
   struct FF_DATA *ff_data = (struct FF_DATA *) info->ff_data;

   return ff_data->data.ff_fsize;
}

Posting compiler error messages would probably help you avoid answering lots of questions

it has told me that there is a parse error before 'struct' and then says that ff_data is undeclared

EDIT:

there are several places in the original file that this works, but the code i wrote at the beggining of this poste is at the end of the file and is the only thing not compiling

would flipping the first and second lines of the function fix the problem?

as for:

its not my code. It is dfile.c of allegro's source code.

when compiling allegro for djgpp i get this error:

src/dos/dfile.c: In function `al_ffblk_get_size':
src/dos/dfile.c:340: parse error before `struct'
src/dos/dfile.c:342: `ff_data' undeclared (first use in this function)
src/dos/dfile.c:342: (Each undeclared identifier is reported only once
src/dos/dfile.c:342: for each function it appears in.)
src/dos/dfile.c:343: warning: control reaches end of non-void function
make.exe: *** [obj/djgpp/alleg/dfile.o] Error 1

this is the same for optimized, debugging and Profiling modes, and the install forum couldn't tell me why.

ive used versions 4.10 and 2.9.5.3 and i get the same error.

EDIT:
this is the original post to the install forum.

i had started having this problem with watcom and was told to use djgpp and ended up with some of the same problems.
