Hi David,
Error src\common\fastmem.c 160: Ambiguous member name 'flags' in function
restart_header
I could reproduce this with Turbo C 3.00 running in DOSBox. It's not a
compiler bug.
If you read the help page of the error message, it applies to
_assembly_code_, in the body of the SET_WORD macro. If multiple structs
have a member with the same name, you have to qualify the member name
with the struct name - but only in assembly code.
Assemblers don't know much about types. They cannot deduce from the
expression "z_header.flags" that to the right of the dot is the "flags"
member specifically of the type of the "z_header" variable (on the left),
"z_header_t", they rather translate this to a general expression like
"address(z_header) + member_offset(flags)" for which the member's offset
must be unambigious.
You can narrow down the problem by inserting this line just below line
160:
asm mov ax, z_header.flags;
and you'll get the same error for this line, too.
Actually, I think, the help page is wrong about the qualification syntax.
You have to change line 160 like this:
SET_WORD(H_FLAGS, z_header.(z_header_t)flags);
or
SET_WORD(H_FLAGS, z_header.(struct zcode_header_struct)flags);
That is, there is no dot between the type qualifier and the member name.
Have fun,
Joe
