Invalid use of incomplete type

[jiake]

A structure including a zero element array can be compiled by Pelles C 7.00.355 (x64):

Code Select Expand

typedef struct {
    int dummy;
    int data[];
} DUMMY_STRUCT;
But a structure with a union including zero element array can't be compiled by Pelles C 7.00.355 (x64):

Code Select Expand

typedef struct {
    int dummy;
    union {
        int padding;
        int data[];
    };
} DUMMY_STRUCT;
Got an error message:

error #2065: Invalid use of incomplete type 'int []'.

I only found one such structure named WNODE_ALL_DATA in "wmistr.h" header until now.

Use -Ze option for that.

[jiake]

-Ze -Zx are all set by default.

It works.
The error should be not in the declaration, but in the usage of the struct.
Post a compilable short piece of code to check.

Upgrade to PellesC V.8.00 RC6
It will solve also SQLITE compiling problem.
